Flight Test

Perform a Function Check Flight (FCF) at the end of maintenance as required by the DA 40 Airplane
Maintenance Manual. Refer to the DA 40 Airplane Maintenance Manual for check flight procedures and
guidance. Always be thoroughly familiar with the G1000/DA40 Airplane Flight Manual Supplement and
Cockpit Reference Guide before performing a flight test.
8.5.1 VHF COM Tests
To check the communications transceivers, maintain an appropriate altitude and contact a ground station
facility at a range of at least 50 nautical miles. Contact a ground station that is in close proximity. Press
the squelch disable button to defeat the automatic squelch feature and listen for any unusual electrical
noise that would increase the squelch threshold. If possible, verify the communications capability on both
the high and low ends of the VFH COM spectrum. It may be required by the governing regulatory
agency to verify operation of the COM transmitter and receiver at the extents of the ground facility's
service volume. (FAA AC 23-8A)
8.5.2 VOR/ILS Tests
Select a VOR channel within a 40 nautical mile range. Listen to the VOR audio and verify that no
electrical interference such as magneto noise is present. Check the tone identifier filter operation. Fly
inbound or outbound on a selected VOR radial and check for proper LEFT/RIGHT, TO/FROM flag
indications on the CDI. Check the VOR accuracy. It may be required by the governing regulatory
agency to verify operation of the VOR receiver at the extents of a ground facility's service volume.
