4–16 ETE – INTERACTIVE FD/LS CHECK (cont)
4–16
TASK
RESULT
CAUTION
During on command DASE FD/LS, cyclic
sticks, collective sticks, and directional
pedals will move. Any restriction of flight
controls may result in damage to the
SPAD shear pins.
Degradation of HARS navigational
accuracy occurs if HARS switch (fig.
2–15) is placed in the OPR position for an
extended length of time and aircraft
remains stationary.
When outside air temperature is above
25C (77F), do not perform rotor blades
de–ice checks for periods longer than
10–minute intervals. Failure to comply
with this precaution could result in
damage to aircraft components.
Do not turn PNVS power on immediately
after power was turned off. This may
damage the PEU.
Make sure the stabilator is clear of all
obstructions before proceeding with the
FD/LS check. Failure to comply could
result in damage to aircraft components.
NOTE
Periodically during the ETE check, the test is
interrupted by advisory messages and prompts
which require operator interaction.
e. On DEK, press and
release ABC/1 and
PQR/6 keys (ADC).
On CDU, press and
release 1 and 6 keys
(ADD).
All FD/LS maintenance tests
(FD/LS checks) for all
systems with the exception of
FD/LS menu addresses 4
(ACZ), 7 through 19 (ACY)
and 33 through 36 (ADD) are
automatically initiated
sequentially. A complete list
of the current NO–GO
messages is displayed upon
completion of the ETE check.
