Panthera

Project story:

Years ago, people said it is impossible to produce an aircraft light and streamlined enough to be safe and efficient. We did it. People said it is impossible to fly around the World in a small aeroplane without assistance. We did it. People also said it is impossible to produce an aircraft fast enough and efficient enough to be successful at the NASA Centennial Challenges. We went ahead and did what nobody did before – we won the NASA Challenges twice. Now they say it is impossible to make a practical electric-powered aircraft presently. We did it already back in 2007 with the first electric two-seater in the World. Clearly we see and do things differently and have a pioneering vision.

It is important to highlight Panthera’s key outstanding characteristics:

Innovation:

Panthera is designed by applying the most modern design and construction techniques, on top of 30 years of knowledge, experience and excellence in building aircraft. Panthera’s organic curves are a product of optimization through advanced, in-house developed computer tools, where each detail is designed to ensure minimum drag and maximum efficiency.

It is specially optimized to ensure minimum noise and maximum performance, reducing the aircraft’s environmental footprint and increasing cabin comfort. Panthera also features all-electric systems for component actuation. Its titanium trailing-link undercarriage, flaps and trim are all electrically operated, resulting in low weight and maximum reliability by removing the need for complex and heavy hydraulic systems. All internal and external lighting is realized using state-of-the-art LED technology, providing for better clarity, recognition and feel.

Performance:

Panthera achieves unprecedented efficiency through careful aerodynamic shaping, retractable titanium undercarriage, lightweight advanced composite structure, a tailor-made propeller and a dedicated performance exhaust system. Efficiency is translated directly into more speed for the same power. No other four-seat aircraft exists that flies this fast on the same engine! For the owner/operator this represents significantly lower operating costs and simplified maintenance.

The maximal range is available with any payload, something which pilots of four-seat airplanes have been wishing for. The robust design of the undercarriage and low overall weight allows for operations from short grass strips, taking you as close as possible to your desired destination. The engine is ready for the future, able to accept unleaded fuels and meeting the future environmental requirements. Hybrid and electric models further reduce the take-off noise footprint by taking advantage of the pure-electric take-off.

Configurations:

Panthera

The first choice of engine was the Lycoming IO-390, but we received the news that it will never be certified for Mogas. Due to this and the fact that Pipistrel had made the decision to use Mogas (automotive gasoline) as it is lower prices and pollutes less (no lead), we were forced to switch to IO-540-V, which is already certified also for the Mogas, even though the Panthera does not need a stronger engine. Since it doesn't need this additional power, it will fly at very low power settings and consumption will consequentially stay more or less the same as with the IO-390 model, but the IO-540 260 hp option will provide a significant performance improvement. See all the data below.

Panthera Hybrid

The 145 kW hybrid-electric powertrain, supported by the state-of-the-art battery system and range-extender generator unit, which is a special in-house development for the Panthera is a true revolution in aviation! The ability of noiseless, pure-electric take-offs and landings is coupled with uncompromised range characteristics. Short-field, powerful climb, extreme aeroefficiency and long-range, which are signature to Panthera are further enhanced with the revolutionary hybrid powertrain. Panthera Hybrid represents a quantum leap forward in thinking and will pave the way for the future of aviation!

Panthera Electro

This version of Panthera with its pure-electric 145 kW powertrain is a treat for the high-tech enthusiasts and those to whom the environment matters. The goal is to demonstrate the ability of covering 400 km (215 NM), quietly, efficiently, with absolutely zero emissions and for a fraction of cost. The platform is open and ready to accept future generations of battery technologies, which will increase the operating range. Electric flight is ready and Panthera Electro will hopefully shift the authorities to rightfully accept electric flight and enable clean, quiet and cheap flight.

Cabin Comfort:

One of the major design points of Panthera is the state-of-the-art ergonomic cabin. All features provide superior comfort and usability for people of all sizes. Access is easy via three large gull-wing style doors, two in the front for pilot and co-pilot and one for the back row of seats. Pilot and co-pilot seats are adjustable. The central stick is ergonomic and provides the sporty feel signature to Panthera. The two back seats are very wide and convenient. There is a supersized – standard cabin luggage sized – cargo door, but the cargo can also be accessed from the cockpit during the flight! The interior is furnished with the highest quality leather and LED lighting for exclusive feel and functionality. Climate is controlled thanks to the on-board air-condition with automatic ventilation (optional). It will keep you cool during the summer and warm during the winter. Also special is the solar-powered ventilation which keeps the cabin cool when Panthera is parked outside in the sun.

Materials and technology:

Each detail of Panthera’s graceful lines has been thoroughly aerodynamically optimized using customized, state of the art computational fluid dynamics software, resulting in a smooth and clean shape. The specially designed wing airfoils are optimized for cruise efficiency and therefore speed, while at the same time ensuring high maximum lift and docile stall characteristics. Its instantly recognizable T-tail ensures low interference drag and helps improve spin characteristics by preventing the horizontal stabilizer from shadowing the rudder at high angles of attack.

Realizing Panthera’s aerodynamic shape while still ensuring maximum safety and keeping the weight low would be impossible without the use of advanced next-gen materials. The majority of the structure of the aircraft is made from carbon-fibre composites, with antistatic materials and Kevlar used in areas where it matters. The retractable trailing-link undercarriage is built from titanium, giving it superior strength and energy absorption properties at minimum system weight. All actuation systems on the aircraft are fully electric, avoiding the need for complex and heavy hydraulics.

Safety:

Panthera is your personal high performance bubble of safety! As part of the rich serial equipment, Panthera features a full-airframe parachute rescue system, which was specially developed, so it can be deployed at both low- and high speeds as well as low altitudes.

The cabin has been engineered as a safety cell/roll bar with built-in energy absorption zones, providing superior safety to the occupants in the event of an accident. The seats and safety belts are engineered to the latest +26G CS/FAR-23 certification standards. Immediately noticeable is the incredible view from the cockpit. By having just one central pillar, the pilot’s view forward and sideward is virtually unobstructed, thus greatly improving the safety of flight. The ergonomic cockpit comes with special annunciation panels, improving situational awareness when it comes to different audio and visual alarms (terrain, stall, overspeed, engine issues, etc.).

Panthera’s performance also contributes to safety – the lightweight structure, powered by powerful engines means that you will reach safe speeds and altitudes much quicker than usual, reducing time spent in the »critical zones«. Special attention has been paid to realize the aerodynamic shape, which gives Panthera excellent handling at low speeds and superior stall/post-stall characteristics. Also important are tailored solutions to simplify maintenance, thus reducing the probability of mistakes occurring during the check-ups.

Pipistrel Panthera

The Pipistrel Panthera is a lightweight, all-composite, highly efficient four-seat aircraft under development by Pipistrel of Slovenia.[3][6][7][8][9]

The gasoline-powered version of the Panthera is intended to cruise at 198 KTAS (366.7 km/h) at FL 080 for over 1,000 nmi (1,852 km) with a 14.8 gph (56 L/h) fuel burn. There are two other versions planned, one with a 145 kW hybrid-electric power system, and the other with a 145 kW pure electric system. These two latter variants will only seat two people to accommodate the electric systems.[3][6][7][8][9]

The company is offering the Panthera as an experimental aircraft, either factory-built or as a kit for amateur construction, with the type certified variant expected in 2022.[4]

Design and development[edit]

Pipistrel Panthera roll-out

In May 2011, Pipistrel was working on constructing the prototype, powered by the Lycoming engine, with all of the aircraft molds already completed. The first flight was planned for autumn of the same year, with the aircraft being tested the following summer with the electric technologies derived from the Green Flight Challengeelectric Taurus project. It will be initially offered in kit form, and Pipistrel indicated that construction will take place in Italy.[10]

Features of the aircraft will include an airframe ballistic parachute designed for use at high speeds and low altitudes[11] and a glass cockpit.[3] The Pipistrel Panthera has an all-composite airframe, made from carbon fiber, glass fiber, and kevlar, and it sports trailing-link electrically-retractible landing gear made of titanium and aluminum alloys,[12] which will be of benefit for operations from grass runways.[13] The composite materials used for the exterior of the aircraft were selected in part based on their ability to withstand lightning strikes,[14][15] which merit increased consideration when employing composite materials instead of a traditional aluminum airframe.[16]

In March 2014 it was announced that the intended Lycoming IO-390 powerplant will be replaced by a six-cylinder Lycoming IO-540. The change was made due to Lycoming Engines not planning to certify the IO-390 for automotive fuel as an option. The IO-540 will provide the same cruise performance and fuel economy, but weighs 41 kg (90 lb) more. However, it will allow the Panthera's gross weight to be increased by 95.25 kg (210 lb) to make up for the extra weight. The aircraft will use the existing cowling, which was originally designed to accommodate a six-cylinder engine anyway.[17]

Operational history[edit]

Pipistrel Panthera public presentation at AERO Friedrichshafen 2012

A test article was introduced at AERO Friedrichshafen 2012 in April 2012. On March 29, 2013, the Panthera had its first successful engine start, using a 210 hp (157 kW) Lycoming engine,[18] and subsequently began taxi tests[18][19] in preparation for the "complete flight test programme".[18] The Pipistrel Panthera made its 54-minute maiden flight less than one week later on April 4, starting the evaluations of performance, handling and systems in flight.[1][2] Less than one month later, the Panthera flew over the Alps to the Aero fair at the Friedrichshafen Airport.[20]

The EU funded the Hypstair program over three years till 2016: a Panthera mockup received a serial hybrid-electric powertrain, ground testing a 200-kW motor driven by batteries only, by a 100-kW generator-only and by both combined. It is followed by Mahepa project from 2017, EU-funded over four years. The Panthera drivetrain will be divided in modules: electric motorthrust generator and internal combustionpower generator in the nose, human-machine interface and computing, fuel and batteries in the wing. Ground testing is planned for 2019 before flight tests in 2020.[21]

Pipistrel Panthera - Spin recovery after 10 rotations
Avatar for Michael Maya CharlesByMichael Maya Charles | July 5, 2021

Estimated reading time 12 minutes, 28 seconds.

It sits low to the ground: nose high, tail low, as if about to pounce — fitting of an aircraft named after a wild cat. Low frontal area, with long, tinted canopies opening upward like a classic Mercedes 300SL Gullwing; sexy-smooth, mostly carbon-fiber and Kevlar skin; tapered wings with short, graceful swept tips; and a tiny ballerina waist aft of the cabin connecting T-tail and tail feathers. All of this whispers: “Eat my dust.” This is not your father’s Suburban. Or Bonanza. A Cirrus looks like a Studebaker, by comparison.

This brand new airplane, the only one in the wilds of North America when it visited my Colorado airport in mid-December, is called a Pipistrel Panthera, and it’s made in Slovenia. Andrew Chan and Shavonna Reid of Florida’s Right Rudder Aviation — the exclusive Americas dealer for the new type — were kind enough to accommodate Skies on short notice during their tightly-choreographed American tour. We wiggled a quick look and short flight into the mix, between two scheduled demos (to people who potentially wanted to spend real money to own one). Though we didn’t get as much time as we would have liked for an in-depth pilot report, and didn’t see a pilot’s operating handbook, we wanted to share our brief experience with this alluring machine.

Walkaround and Climbing Aboard

My first impression of this sleek plane is that the fit and finish are very good. A few notes: There are no cowl flaps; LED strobes and nav lights hide elegantly in the swept wing tips; there are 11 gear doors on this critter; and the tail feathers seem small. A familiar Lycoming IO-540 engine, rated at 260 horsepower, swings a broad-chord composite MT propeller. The Lycoming will be certified to run on avgas or auto fuel. On the Panthera, standard fuel is only 27 gallons (102 liters) per side, or 54 gallons total, which seems light for an IO-540-powered airplane. Long range fuel is an available option for an extra $50,000; those additional tanks are installed aft of the spar, bringing the total fuel to 39 gallons per side. I can’t imagine any serious IFR cruiser not opting for the extra fuel. 

There’s no handhold on the side of the cabin for boarding. But you can grab the doorframe (if the canopy’s open) to help you up onto the wing. You step in and sit down in the Panthera — not on top of it like a Bonanza or Cirrus. The semi-supine, stitched leather seating is comfortable, and offers firm, sports car-like support. Settling in, you reach up and pull the big, tinted canopy closed quite easily (no need to slam). I noted a couple of inches of clearance between my headset and the canopy.

With short center control sticks between your knees, and engine controls and fuel selector in the center console, the cockpit layout is at once familiar. Visibility above and to the sides is great, but the broad, centerline structure restricts the view forward — like some tailwheel airplanes I’ve flown. Think: European. Maserati.

The panel offers familiar Garmin avionics, with dual G3Xs, a GTN 750Xi and 650Xi in the center stack, coupled with a Garmin GMC 307 autopilot on this experimental-exhibition version; a GFC 500 will be available on the certified model. The gear selector, flap switch, and a Mid-Continent Standby Attitude Module (SAM) backup instrument sit prominently in the upper center of the panel.

Before starting up, you arm the full-airframe parachute, much like the drill on a Cirrus. Lighting up the Lycoming is conventional. But taxiing the Panthera takes a little getting used to, partly because of the high glareshield and the forward view limitations; from my seating position (I’m around five-foot-10), the bottom of the windshield intersects with the ramp quite far ahead. Pipistrel will offer another seat option for taller pilots.

As we taxied, I was also aware of the tall taxiway lights at Erie Airport (KEIK); we cleared them all, but the airplane’s low stance requires mindfulness.

Toe brakes feel tight, with very little travel or feel. Right Rudder Aviation’s Chan requested I hold brakes and bring up the power before takeoff, and I found it challenging to keep the airplane from creeping forward.

Let’s Fly!

Fifty-three degrees Fahrenheit (12 C) and 5,100 feet field elevation gave us a density altitude of just under 6,000 feet for the day’s performance.

Holding slight aft stick resulted in a surprising pitch up as the tail became effective, resulting in over-rotation on my first takeoff. But Chan was ready for it; I’m sure he’d seen it before on other demos. With that new awareness, my second takeoff was smooth with no pitch excursion.

The best rate of climb is 100 knots, but visibility over the nose at that speed is not good; I flattened to 130 knots, and rate of climb bounced between 1,000 to 1,300 feet per minute with two of us and half fuel on board.

Here are my initial impressions of the Panthera’s handling qualities: Pushrods in both the elevator and ailerons provide a positive feel; a little light in the pitch, perhaps (surprising for the size of the tail feathers), and a little thick in the roll. The rudder is the only cable-actuated surface, and yaw response is what the aero guys call “deadbeat.” All good traveling machine traits, actually.

We leveled at 7,500 feet to stay below our Class B airspace, and accelerated easily to about 185 knots true airspeed (TAS), on 13 gallons per hour. From what I saw in my short taste, I suspect the Panthera is not quite a 200-knot airplane, though it certainly could make it into the 190s if you poured enough fuel through the pipes.

Chan assures me he plans cross-countries at 185 knots TAS on 10.8 gallons per hour, lean of peak, and estimates a range of 800 nautical miles with no wind. Pipistrel’s marketing claims “1,000 nm, four passengers at 200 knots,” but from my small sample, it doesn’t appear that it can do all three at once. The empty weight of the test airplane was about 1,800 pounds, leaving 1,100 lbs. for fuel, people, and bags. Again, it’s a sports car, not an SUV.

Stalls were not exciting (which is how we like them), with plenty of warning, a pretty definite break, and ample rudder, aileron, and pitch control throughout the stall.

The Cabin

There’s a third cabin door behind the pilot seat for the passengers, but I didn’t sit in the back because, well… who cares in an airplane like this? Ever sit in the back of a Porsche? (Actually, I didn’t want to overstay our welcome because real, prospective buyers were waiting patiently at the ramp when we parked after our flight.)

The baggage compartment — which is accessed from the outside, aft of the passenger door — seemed a bit on the small side. Chan calls it “medium size” — which depends on what you compare it to. I would say, it’s smaller than Cirrus’s offering.

Descending back into Erie at a gradual 200 to 300 feet per minute, the slippery-smooth, low-drag airframe inadvertently lured me well into the yellow airspeed caution range — almost to the never exceed speed (Vne) red line of 205 knots. Chan quietly called my attention to the speed (I’m guessing he’d seen that before, too), and I reduced the power significantly.

Leveling at pattern altitude, I set 10 inches of manifold  pressure and waited for the slippery bird to slow to the low 106-knot speed limit for flaps and gear. Though Pipistrel insists you don’t need speed brakes — and doesn’t plan to offer them — I would posit that we don’t always have the luxury of “planning” descents in the busy air traffic control world; or when descending from high cruise altitudes (especially in the U.S.’s mountainous west) when it’s often bumpy.

Once the wheels and flaps are down, drag rise is high; it takes a substantial amount of power (18 to 19 inches manifold) to stay on speed — even after Chan had removed one door in front of the nose landing gear when we flew.

Chan recommended an approach speed of 70 to 75 knots, and that seemed to work well. There’s not much to see over the nose as you transition to flare, so you naturally drop your view to the sides of the cowling to keep the runway in sight. My first landing looked about right to me, but resulted in touching down only slightly above a three-point attitude. The trailing link landing gear made me look like a hero, anyhow.

On my second landing, I raised the nose higher, which pretty much eliminated all forward view. Chan called for “left rudder…” in the flare to align with the centerline, though I couldn’t detect the need. He says many who fly the Panthera have a hard time seeing that subtle alignment.

Regardless, the second touchdown was a satisfying mains-first, nose-high arrival. I held the nose wheel off until about 50 knots, being careful not to drag the low tail. That was more elevator authority than I expected, but as I noticed in my first takeoff pitch excursion, the clean airflow across the T-tail is quite effective.

Step Right Up!

Right Rudder Aviation is currently offering both experimental-exhibition and certified Panthera aircraft delivery positions. Once certified, the experimental-exhibition version will no longer be available. At press time, Pipistrel had deposits for more than 150 aircraft worldwide, with about 50 planes scheduled for delivery in the U.S. The OEM is shooting for European Union Aviation Safety Agency (EASA) certification first, followed immediately by U.S. Federal Aviation Administration (FAA) certification. Realistically, with all the worldwide challenges due to the coronavirus, Chan admits FAA certification probably won’t happen until sometime in 2023.

Pricing of the Panthera is preliminary, but expect about US$650,000 for the experimental-exhibition version, and $750,000 for the certified aircraft. Most people are adding air conditioning, a 50-pound option, and “some” are opting for the long-range tanks, according to Chan.

Can Pipistrel support a fleet of these aircraft from Slovenia? That remains to be seen; though as any offshore OEM will tell you, support for a product after the sale takes a monster commitment of funds, parts, and training.

With style, speed, and efficiency, this beauty aspires to be the “perfect personal airplane.” When you pull up to the FBO in your Panthera, you are certain to attract more eyeballs than a pack of pedigree dogs. Or a sleek, wild cat.

DESCRIPTION

PANTHERA:

Unique 4-seater with an attractive design and efficient performance!

The sky has opened-up like never before and borders are falling every day. The need for travelling long distances quickly and efficiently has never been greater. Imagine an airplane, that can fully take advantage of small, short-runway airfields that bring you closer than ever to your destination or fly around the world and open a whole new world of opportunities. Panthera is an airplane that is carefully designed to keep you safe, comfortable, being at the same time quiet and friendly to the environment. It is an innovative airplane, which instantly catches attention.

Panthera has been designed from the very beginning to be available with either electric engine, hybrid propulsion or petrol engine – in this case, Pipistrel decided for Mogas fuel due to lower price and better availability in several parts of the world comparing to Avgas.

It is important to highlight Panthera’s key outstanding characteristics:

Panthera is designed by applying the most modern design and construction techniques, on top of 30 years of knowledge, experience and excellence in building aircraft. Panthera’s organic curves are a product of optimization through advanced, in-house developed computer tools, where each detail is designed to ensure minimum drag and maximum efficiency.
It is specially optimized to ensure minimum noise and maximum performance, reducing the aircraft’s environmental footprint and increasing cabin comfort. Panthera also features all-electric systems for component actuation. Its titanium trailing-link undercarriage, flaps and trim are all electrically operated, resulting in low weight and maximum reliability by removing the need for complex and heavy hydraulic systems.  All internal and external lighting is realized using state-of-the-art LED technology, providing for better clarity, recognition and feel.

Panthera achieves unprecedented efficiency through careful aerodynamic shaping, retractable titanium undercarriage, lightweight advanced composite structure, a tailor-made propeller and a dedicated performance exhaust system. Efficiency is translated directly into more speed for the same power. No other four-seat aircraft exists that flies this fast on the same engine! For the owner/operator this represents significantly lower operating costs and simplified maintenance.
The maximal range is available with any payload, something which pilots of four-seat airplanes have been wishing for. The robust design of the undercarriage and low overall weight allows for operations from short grass strips, taking you as close as possible to your desired destination. The engine is ready for the future, able to accept unleaded fuels and meeting the future environmental requirements. Hybrid and electric models further reduce the take-off noise footprint by taking advantage of the pure-electric take-off.

One of the major design points of Panthera is the state-of-the-art ergonomic cabin. All features provide superior comfort and usability for people of all sizes. Access is easy via three large gull-wing style doors, two in the front for pilot and co-pilot and one for the back row of seats. Pilot and co-pilot seats are adjustable. The central stick is ergonomic and provides the sporty feel signature to Panthera. The two back seats are very wide and convenient. There is a supersized – standard cabin luggage sized – cargo door, but the cargo can also be accessed from the cockpit during the flight!  The interior is furnished with the highest quality leather and LED lighting for exclusive feel and functionality. Climate is controlled thanks to the on-board air-condition with automatic ventilation (optional). It will keep you cool during the summer and warm during the winter. Also special is the solar-powered ventilation which keeps the cabin cool when Panthera is parked outside in the sun.

  • Materials and technology:

Each detail of Panthera’s graceful lines has been thoroughly aerodynamically optimized using customized, state of the art computational fluid dynamics software, resulting in a smooth and clean shape. The specially designed wing airfoils are optimized for cruise efficiency and therefore speed, while at the same time ensuring high maximum lift and docile stall characteristics. Its instantly recognizable T-tail ensures low interference drag and helps improve spin characteristics by preventing the horizontal stabilizer from shadowing the rudder at high angles of attack.
Realizing Panthera’s aerodynamic shape while still ensuring maximum safety and keeping the weight low would be impossible without the use of advanced next-gen materials. The majority of the structure of the aircraft is made from carbon-fibre composites, with antistatic materials and Kevlar used in areas where it matters. The retractable trailing-link undercarriage is built from titanium, giving it superior strength and energy absorption properties at minimum system weight. All actuation systems on the aircraft are fully electric, avoiding the need for complex and heavy hydraulics.

Panthera is your personal high performance bubble of safety! As part of the rich serial equipment, Panthera features a full-airframe parachute rescue system, which was specially developed, so it can be deployed at both low- and high speeds as well as low altitudes.
The cabin has been engineered as a safety cell/roll bar with built-in energy absorption zones, providing superior safety to the occupants in the event of an accident. The seats and safety belts are engineered to the latest +26G CS/FAR-23 certification standards. Immediately noticeable is the incredible view from the cockpit. By having just one central pillar, the pilot’s view forward and sideward is virtually unobstructed, thus greatly improving the safety of flight. The ergonomic cockpit comes with special annunciation panels, improving situational awareness when it comes to different audio and visual alarms (terrain, stall, overspeed, engine issues, etc.).
Panthera’s performance also contributes to safety – the lightweight structure, powered by powerful engines means that you will reach safe speeds and altitudes much quicker than usual, reducing time spent in the »critical zones«. Special attention has been paid to realize the aerodynamic shape, which gives Panthera excellent handling at low speeds and superior stall/post-stall characteristics. Also important are tailored solutions to simplify maintenance, thus reducing the probability of mistakes occurring during the check-ups.

DISCOVER

[ Innovation ]

Special attention has been paid to engineer the aerodynamic shape, which gives Panthera excellent handling at low speeds and superior stall/post-stall characteristics. Panthera's organic curves are a product of optimization through advanced, in-house developed

computer tools, where each detail is designed to ensure minimum drag and maximum efficiency. This allowed for Panthera to be designed and flown in a virtual environment with a great degree of accuracy even before the first component was produced.

[ Configurations ]

The retractable landing gear features a full trailing link design with an oleo-pneumatic suspension element on all three wheels. The main undercarriage struts are innovatively built from grade five titanium for increased robustness, light weight and care free operation on standard and/or rugged runways.

[ Cabin comfort ]

The instrument panel is designed to embrace the pilot and provide ultimate sensation, while optimizing outside visibility. By having just one central pillar, the pilot's view forward and sideways is virtually unobstructed, thus greatly improving the safety of flight.

Exquisite and hand crafted leather shapes the interior of the Panthera. Seating comfort is guaranteed by a selection of materials with different softness. The result is a breathable, multi zone support seat, making those 1000NM flights your best travel experience.

[ Instruments ]

Years of research in human interface and ergonomics contributed to the superior design of the cabin and the pilot space. As soon as you grab the power lever, you feel the Panthera experience. The innovative and patented 3D trim interface allows the pilot to trim the aircraft in a quicker, more intuitive and precise way.

On the full IFR panel there are three functional areas: the upper back-up/annunciator area, the PFD/MFD area and the communication stack. The avionics are gathered around a Garmin G500 series PFD/MFD synthetic vision screen and the new state of the art Garmin GTN series touch-screen Flight Management Systems.

[ Safety ]

Panthera features a full-airframe parachute rescue system, which was specially developed to allow deployment at both low and high speeds, as well as at low altitudes. The cabin has been engineered as a safety cell/roll bar with built-in

energy absorption zones, providing superior safety to the occupants in the event of an accident. The seats and safety belts are engineered to meet the latest +26G CS/FAR-23 certification standards.

[ Materials & Technology ]

Realizing Panthera's aerodynamic shape while still ensuring maximum safety and keeping the weight low would be impossible without the use of advanced next-gen materials. The majority of the aircraft structure is made from carbon-fibre composites,

while antistatic materials and Kevlar™ strengthen the construction. The retractable trailing-link undercarriage is built from titanium, giving it superior strength and energy absorption properties at minimum system weight.
