All system functions that cannot be adequately tested on the ground will require a flight test. Even if all
functions can be verified on the ground, a flight test is recommended as a final installation verification.
Verify system operation as described in the following sections.
3.3.3.1 Com Flight Test Check
1.
Verify the com performance by contacting a ground station at a range of at least 50nm while
maintaining an appropriate altitude, and over all normal flight attitudes. Performance should be
checked using low, high, and mid band frequencies.
3.3.3.2 VOR Flight Test Check
1.
Tune a local VOR station within 50 miles.
2.
Verify the audio ident/voice quality.
3.
Verify the Morse code decoder IDs the station (95% probability).
4.
Fly to and from the station.
5.
Verify NAV flag, TO/FROM flag, and CDI are operational.
6.
Record accuracy in System Log (see manual).
3.3.3.3 ILS Flight Test Check
1.
Tune an ILS at the local airport.
2.
Verify the audio ident/voice quality.
3.
Verify the Morse code decoder IDs the station (95% probability).
4.
Fly the approach.
5.
Verify NAV flag, GS flag, and CDI and VDI are operational.
6.
Verify BC annunciator.
3.3.3.4 GPS Flight Test Check
1.
Verify that GPS position is not lost during normal aircraft maneuvering (e.g. bank angles of up to 30
degrees and pitch angles associated with take-off, departures, approaches, landing and missed
approaches as applicable). If GPS position is lost, a “
WARNING Loss of Navigation
” message will
be displayed.
2.
Enter and activate a flight plan on the CNX80. Fly the flight plan and verify that the display of flight
plan data is consistent with the CDI indication (deviation, TO/FROM…) in the pilot’s primary field of
view.
3.3.3.5 Autopilot Flight Test Check
1.
Enter and activate a flight plan on the CNX80. Engage the autopilot in the GPSS mode. Verify that
the autopilot flies the course.
2.
Disengage the autopilot and fly off course. Re-engage the autopilot (in GPSS mode) and verify that it
correctly intercepts the course and continues to fly it.
3.
Turn off the autopilot GPSS but leave the autopilot engaged in Nav mode. Verify that it maintains the
current course.
