Maiden Flight

Pipistrel’s new Panthera completed its maiden flight on 4 April, 2013.
The very successful first flight lasted 54 minutes!

Having completed ground functional and taxi tests at Pipistrel’s Headquarters at Ajdovscina, Slovenia, the Panthera relocated to the Airport of Cerklje ob Krki, where Slovenian Armed Forces are providing us invaluable logistics support.

Following high-speed taxi runs and jumps above the runway, test pilot Mirko Anžel and co-pilot Sašo Knez lifted off the runway at 14:15 local time and spent 54 minutes in the air, evaluating Panthera’s behavior and performing system checks.

Both pilots agreed the handling was straight-forward and pilot friendly, with parameters exactly as predicted – a true statement to skill of the development team and reassurance that all target performance goals will be met. Panthera so far completed several hours of flying with undercarriage both out and retracted.

Performance

Pantera

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 does not only reflect itself in a low fuel consumption of just 10 gallons per hour at 200 kts, but 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 1000 NM range is available with any payload, something which pilots of four seat aeroplanes have been wishing for. 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.

Instruments

Pantera
The instrument panel is designed to embrace the pilot and provide ultimate sensation and outside visibility. The view from the cockpit is completely redefined by a using a single pillar between the pilots – in this way the visibility forward and sideward is free of obstacles, greatly increasing the safety of flight.

There are three functional areas on the full IFR panel, 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. The ease of use and reliability of Garmin avionics is second to none, but the cockpit environment of the Panthera further enhances the experience. The GTN 750 and 635 dual COM/NAV feature full touch screen controls, which maximise screen size and allow for simplified navigation and graphical flight planning. Draw a path on the navigation screen with your finger and Panthera’s full featured autopilot can follow it. It’s magic! In addition, the fully integrated modular cockpit provides all terrain, traffic and weather alerts (in areas where applicable). Transponder and 3D audio-panel are integrated and courtesy of the Garmin GTN 750.

Frequently Asked Question

EQUIPMENT

Will there be air brakes available?
Airbrakes (speed brakes) will not be offered initially, but there is space to integrate them later in the process of development.

Is there an option for more advanced G2000 and Garmin autopilot?
Garmin G2000 is only available to Cessna at the moment, they apparently paid for part of the development and will be using the system in light jets and turboprops. We are talking to Garmin but currently it does not look like we will get it. Anyhow, the G500 and GTN750 series combination has very similar capability than the G2000 with similar level of integration and even offers touch-screen programing which is really simple and easy to learn.

Will Garmin GTN 635 have to be upgraded to a GTN 650 if so required by CAA for IFR traffic? (same box but with VOR/ILS/GP)
You have the VOR, ILS and GP capability already in the GTN750. The 635 is envisioned as a COM/GPS complement to the 750. The 650 would only be necessary if you needed two VOR/ILS receivers which is a bit of an overkill in these days. With the standard 750+635 setup (for both experimental and certified versions), you get 2x COM, 1x NAV, 1x ILS, 2 x IFR GPS, full integrated 3D intercom and ADS-B mode S transponder.

Why the Trutrak Autopilot?
The trutrak is only there for the Experimental version. The certified one will use the S-tec or Garmin digital autopilot.
Avidyne R9 have been considered as well, but are not competitive with their pricing.
When going for the experimental, the Avidyne could be installed at a surcharge, of course.

Is TKS de-icing available?
TKS (de-icing with glycol) will be available later, the wing is prepared for the installation of it.

Have you looked at the FADEC i.e.2 option from Lycoming?
The IE2 Lycoming is not available for the power range we are looking for the Panthera. It is only available as the turbocharged 300+ HP 6 cyl engine. The IO-390 was actually chosen as the engine because Lycoming says it will be the engine which they will use to make it the first IE-2 4 cylinder engine.

Are there any plans to add a turbo-charged engine?
Not at the moment, no.

In some places there is still ADF and DME required for IFR flying. Can you add this (at additional cost) if required ? Is there space reserved for this in the panel?
There is only one vendor that still makes ADFs, Bendix King. In worst case, there is still space on the Panel, but EASA does not require the ADF any more.
The G500 display can be configured to show DME calculated data and this is accepted by EASA for IFR primary.

What are the size of tyres? Are they suitable to use on grass-strips?
Tyre size on main wheels is 5.00×5, nose wheel is 5.00×4. The undercarriage itself was designed to be used on grass strips, hence the use of titanium and each landing gear strut
(nose, main left and main right) have ole-pneumatic dampers. Panthera will definitely have THE undercarriage to be used on grass, light and robust with full shock absorption.
In some places, they have snow and and winter debris on the runways in the winter. Are you open for input to have brake discs rather high up as well gear doors in order to handle winterflying?
The wheel doors are higher than half of the wheel, so it is as high as any design can be made. The wheel brake discs are unproblematic, we believe, as they are of floating type (Beringer high performance)

Is it possible to install additional fuel tanks above 250 litres ?
It is possible but what would be the desired fuel tanks? 1000 NM range is enough for most cases, however there is space in the wing for more fuel.
Then of course full fuel payload will be less as MTOW would stay at 1200 kg.

PERFORMANCES

What altitude gives fastest cruise speeds?
Fastest cruise speeds are between 8000 and 14000 ft (large laminar bucket on airfoil), but actual top TAS will occur at 11500 ft.

You claim the speed of 202 knots. At which altitude?
At FL95. The exact figure will be determined through testing.
What would be the fuel consumption at 50% power?
At 50% power the Panthera is flying slower, but closer to aerodynamically best cruise regime (less drag at lower speeds), so the
mileage is slightly improved at 21.7 versus 20.6 at 75% regime. At FULL power, the speed is 208 kts, while burning 13 gph at 10000 ft, coming
to a millage of 16.5 NM per gallon of fuel traveled.

CABIN COMFORT

Is the aircraft equipped with the electric pitot heating?
Of course! If you look carefully there is a dedicated switch on left side of instrument panel, where the main power
