Electronic Flight Instrument System (EFIS)
EFIS Preflight Self--Test
To run the EFIS self--test, push and hold the TEST button on the DC and
verify the following:
NOTES:
1. The EFIS test is only functional when the aircraft is on
the ground. The test is functional at all times except
during GS CAP/TRK.
2. A localizer frequency must be tuned on both NAV
receivers to annunciate ILS.
3. Self--test is limited to radio altimeter test only in the air
and is inhibited after glideslope capture.
4. FD FAIL annunciation is not displayed during a
pilot--initiated test.
5. If the aircraft is on the ground and the DC TEST button
is pushed longer than 5 or 6 seconds, the system enters
the initiated test mode. Refer to Section 9,
Troubleshooting, for information about initiated testing.
