1. A localizer frequency must be tuned on both
NAV receivers to annunciate ILS.
2. Self–test is limited to radio altimeter test only in
the air and is inhibited after glideslope or
glidepath capture.
3. If the display controller TEST button is held
longer than 5 to 6 seconds and the aircraft is on
the ground, the system enters an initiated test
mode. Refer to Section 7, Troubleshooting, for
a complete description of the initiated tests.
4. The EFIS test functions only on the ground. The
radio altimeter test functions at all times except
during glideslope capture/track.
5. FD FAIL is not displayed during a pilot–initiated
test.
6. When the display controller fails, MENU INOP
displays in the menu section of the MFD.
7. To ensure that the proper source is being used
with the selected flight director modes when
sources are changed, the EFIS resets flight
director modes as listed in Table 3–2.
