Change 8
6. ASE panel switches – As desired.
7. EXT LT switches – As desired.
8. PARK BRAKE – Release.
9. TAIL WHEEL switch – UNLOCK. Note that
green advisory light illuminates.
NOTE
If the advisory light fails to illuminate, taxi
forward a short distance while making light
pedal inputs.
*8.22. TAXI CHECK.
1. Wheel brakes – Check.
2. Engine/rotor instruments – Check.
3. Flight instruments – Check.
8.23 TAXI.
CAUTION
Excessive cyclic displacement with
low power settings may result in
droop stop pounding.
Excessive forward cyclic displace-
ment with low power settings may re-
sult in high strap pack loads.
Initiate taxi by increasing collective to 20 to 24% torque
and applying slight forward cyclic pressure as required to
begin aircraft movement. To maintain forward movement
or taxi speed, do not reduce torque below 20%. Control
aircraft heading with pedals and speed with a combination
of collective, cyclic and brakes. Deceleration may be con-
trolled by using collective, aft cyclic, and if required,
brakes. Forward cyclic should be limited to the position
used to initiate taxi. Use slight lateral cyclic into turns to
maintain a level fuselage attitude. Taxiing on soft, rough or
sloping terrain may require the use of more collective than
on smooth, level surfaces.
*8.24. BEFORE TAKEOFF CHECK.
1. HARS switch – Verify OPR.
2. Weapons systems – Safe.
a. Pilot MASTER ARM switch – OFF or SAFE.
b. CPG ARM/SAFE switch – OFF or SAFE.
c. PLT and CPG weapons select switches – As
desired.
d. Ensure weapons not actioned.
3. TAIL WHEEL switch – LOCK.
4. PARK BRAKE – As desired
5. Systems check as follows:
a. FUEL panel switches.
b. Fuel quantity.
c. Engine instruments.
d. Caution/warning panel.
6. PWR levers – FLY.
7. If the DTC overwrites the active fly-to or target, it
is necessary to de-select and re-select the ac-
tive fly-to or target.
8. Power check – Perform. The power check is
done by comparing indicated torque required to
hover with the predicted values from perfor-
mance charts in Chapter 7
or Chapter 7A
.
8.25 BEFORE LANDING CHECK.
NOTE
Prior to landing, external stores may be
placed in the ground stow position by plac-
ing the rocket select switch on either fire
control panel in the GND STOW position.
1. Weapons systems – Safe.
a. Pilot MASTER ARM/SAFE switch – OFF or
SAFE.
b. CPG ARM/SAFE switch – OFF or SAFE.
c. PLT and CPG weapon select switches – As
desired.
d. Ensure weapons are not actioned.
2. ATTD/HOVER HOLD switch – OFF.
3. TAIL WHEEL switch – LOCK.
4. PARK BRAKE – As required.
