WARNING
On helicopters with BUCS activated,
automatic flight control motion occurs when
on command DASE FD/LS is initiated. Make
sure all personnel keep clear of flight
controls immediately after pressing and
releasing keys ()/0 and DEF/2 on the DEK
(ADC) or 0 and 2 on the CDU (ADD).
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 shear
pin activated decoupler (SPAD) shear pins.
NOTE
Begin DASE FD/LS with cyclic stick (fig.2–8
or 2–35) and collective stick (fig. 2–24 or
2–46) centered and do not apply foot
pressure on the directional control pedals.
Special purpose one (SP1) present position
(PPOS) data, magnetic variance (MV), and
spheroid (SPH) data can be obtained from:
Maintenance Officer, S–3 or
Department of Defense (DOD) flight
information publication (FLIP) (e.g.
visual flight rules (VFR) Supplement,
instrument flight rules (IFR)
Supplement, Airport Directory VFR
Sectional) and universal transverse
mercator (UTM) Map.
SP1 data must be within 500 to 750 meters of
present location.
If SP1 data greater than 360 degrees is
entered for magnetic heading or 179.9 is
entered for magnetic variation, the message
ERROR is displayed near the upper left
corner of the display (ACZ).
