Compass (PAI-700 flat card type). This compass is used because the standard ball type
compasses tend to pick up on rotor vibration and oscillate to an extent that is unreadable.
The compass may be panel mounted or remote mounted as required to suit aircraft
magnetic fields. Normal fitment is above the instrument panel.
Materials used
See AutoGyro manual parts list
Assembly methods
All instruments in the panel are fitted with M4 stainless steel dome head screws, with plain
nuts loctited on with 243 – unless specifically supplied with the instruments.
The radio antenna is mounted behind the instrument panel, opposing the transponder
antenna.
Special setup instructions
ASI should be calibrated as an installed instrument with suitable equipment.
Transponder. Follow the Funkwerk instructions for unit setup. Aircraft hex codes are
available from the CAA G-INFO website. After initial setup the unit function must be
confirmed using calibrated, proper equipment – transmitting incorrect codes is an offence.
A transponder is also a radio transmitter, so should be included on the aircraft radio
licence. It is required that the transponder is verified biennially (i.e. every two years) to
ensure what the pilot thinks it is doing it actually is, and that the codes transmitted are
correct.
Transponder installation verification.
On initial aircraft approval the transponder installation and function was verified in
accordance with TGL13. The functional test undertaken is a transponder verification to
confirm a) System operation, b) ICAO 24bit address in transmission response and c)
Function of system fault detectors (where applicable). Each follow on aircraft has the
transponder function verified as part of the release to service for the same features.
Transponder field verification test procedure.
1. Ensure that the correct hexadecimal code has been input by cross checking the code
assigned to the aircraft on the CAA G-INFO website to that in the aircraft – follow the
Funkwerk setup instructions contained in the Funkwerk handbook 03.2121.010.71e.
2. Ensure the aircraft type code is input (1C) and the aircraft registration without gaps.
There are normally three blank spaces at the end of the line. So as an example, the code
for G-CLDS is ‘405F461CGCLDS___’
3. The aircraft has no trigger ‘ground’ switch for indicating that the wheels are off the
ground, so this setup option is left de-activated.
4. Follow the instructions of the verification equipment with regard to setup, and of siting of
the equipment antenna with respect to the aircraft antenna.
5. The verification must check and verify items a), b) and c) above together with the
reported parameter “Pressure altitude” which must be satisfactorily compared with the
aircraft altimeter set at 1013mb. It is preferable to print the test data for evidence of test
completion.
6. Aircraft condition during test – Engine off, ignition on, transponder on and in ‘ACS’
mode. No other equipment is required to be on.
7. Follow the verification equipment instructions for test process.
