Awaiting Flight Testing


With construction complete, we have been packing and organising while we wait for the issue of the requisite flight test permit. The plane now lives in a hangar at the grass airstrip along side our build supervisor Gary's Jabiru which has acted as a useful reference for control and avionics installation.

Our choice of interior colours has turned out well 'in the leather'. We were so pleased that we are now having a few additional memory foam cushions and arm rests made. We opted for a light silver roof lining, mid grey carpet and a deep purple with grey piping seating. Mmmm new aeroplane smell.

This shot shows the front foot wells before rudder pedal installation. The funky door pockets should be great for storing sunnies, maps and energy bars.



This is the black leather clad coaming that mounts to the firewall with the instrument panel (and throttle plungers as seen) in it.



The panel design and construction was one of the best parts of the build. After selecting and laying out the instruments, I cut the alloy sheet to shape, had it powder coated and engraved with each switch and botton's function, then installed the avionics and wired everything up. We took the opportunity to add navigation lights, stobes lights, landing lights and MP3 input. The 'glass cockpit' flight display integrates all primary flight data (airspeed, heading, altitude, engine parameters) with radio navigation and GPS moving map info. Snazzy. The 'steam guages' are backup. I have chosen to include an analogue electric turn coordinator with the two backup instruments required in the UK, airspeed indicator and altimeter. The turn coordinator is a whacky instrument if ever there was one - gyroscopically stabilized (old school, c.f. solid state accelerometer instruments), it indicates a combination of roll and yaw axis rotation which allows a fast response and a good indication of turn direction and rate without a visual reference outside the cockpit. Combining the two axis is a little impure and not much use for aerobatics. Good for its intended job of slothing around the sky at moderate bank angles I suppose so an ideal inertial reference backup for the Jabiru.
