8. MODE ANNUNCIATORS -
The mode symbol located above
each mode button will illuminate when the mode is engaged
except for the NAV and APR modes. When either the NAV, APR or
BC mode button is pressed the appropriate ARM annunciator
above
either the NAV or APR mode button will illuminate until the
automatic beam capture sequence is initiated. At beam capture
NAV or APR will be annunciated above either the NAV or APR
mode button. Normally the NAV or APR coupled conditions follows
an ARM
condition but the coupled condition may be entered into directly
if the beam capture criteria are met when NAV, APR or BC is
selected.
9. PREFLIGHT TEST (TEST) -
Initiates preflight test sequence which
automatically turns on all annunciator lights, tests the roll and pitch
rate monitors, tests the auto trim fault monitor, checks the manual
trim drive voltage and tests all autopilot valid and dump logic. If
the preflight test is successfully passed, the AP annunciator light
will flash for approximately 6 seconds (an aural tone will also
sound for 2 seconds while the annunciator flashes). The autopilot
can not be engaged until the autopilot preflight tests are
successfully passed.

command wings level and pitch attitude hold.
