NOTE
Brakes should be released after chocks are
in place, ramp conditions permitting.
2. Parking brake – As required.
3. Flight controls – As required.
4. OVERHEAD FLOOD LIGHTS – OFF.
5. STANDBY PUMPS – OFF.
6. Windows C – As required. Do not leave
passenger windows in polarized (dark)
position.
7. Emergency exit lock – As required.
8. Galley power switches – OFF.
9. Aft cabin light – OFF.
10. Door light – OFF.
CAUTION
If strong winds are anticipated while the
aircraft is unattended, the propellers shall
be secured to prevent their windmilling
with zero engine oil pressure.
11. Walk-around
inspection
–
Complete.
Conduct
a
thorough
walk-around
inspection, checking for damage, fluid
leaks, and levels. Check that covers,
tiedowns, restraints, and chocks are
installed as required.
12. Aircraft forms – Complete. In addition to
established requirements for reporting any
system defects, unusual and excessive
operation such as hard landings, etc., the
flight crew will also make entries on DA
Form 2408-13 to indicate when limits in
the
Operator's
Manual
have
been
exceeded.
13. Aircraft secured – Check; lock cabin door
as required.
Section III. INSTRUMENT FLIGHT
8-47. GENERAL.
This aircraft is qualified for operation in
instrument meteorological conditions. Flight handling,
stability characteristics, and range are approximately
the same during instrument flight conditions as when
under visual flight conditions.
8-48. INSTRUMENT FLIGHT PROCEDURES.
Refer to FM 1-5, FM 1-230; FLIP; AR 95-1; TC
1-218; FAR 91 (sub parts A and B) or applicable
foreign government regulations and procedures
described in this manual.
8-49. INSTRUMENT TAKEOFF.
Complete the Before Takeoff check. Engage the
HDG mode on the FD. Do not engage autopilot. Set
HDG marker to runway heading. Align the aircraft with
the runway centerline, ensuring that the nose wheel is
straight before stopping aircraft. Hold brakes and
complete the lineup check. Ensure that the roll
steering bar is centered. Power application and PNF
duties are identical to those prescribed for a "visual"
takeoff. After the brakes are released, initial
directional
control
should
be
accomplished
predominantly with the aid of outside visual
references. As the takeoff progresses, the crosscheck
should transition from outside references to the FD
and airspeed indicator. The rate of transition is directly
proportional to the rate at which the outside references
deteriorate. At rotation speed, press the PITCH SYNC
& CWS switch and hold, establish takeoff attitude,
once the desired pitch attitude is attained release
PITCH SYNC & CWS switch. Maintain this pitch
attitude and wings-level attitude until the aircraft
becomes airborne. When both the vertical velocity
indicator and altimeter show positive climb indications,
retract the landing gear. After the landing gear is
retracted, adjust the pitch attitude as required to attain
V2 + 10 KIAS. Use PITCH SYNC & CWS as required
to reposition the FD pitch steering bar. Retract flaps
after attaining 105 KIAS
airspeed and readjust pitch as
required. Control the bank attitudes to maintain the
desired heading. Support FD indications throughout
the
maneuver
by
cross-checking
"raw
data"
information displayed on supporting instruments.
NOTE
Due to possible precession error, the pitch
steering bar may slightly lower during
acceleration, causing the pitch attitude to
appear higher than actual pitch attitude.
To avoid lowering the nose prematurely,
crosscheck the vertical velocity and
altimeter
to
ensure
proper
climb
performance. The erection system will
automatically remove the error after the
acceleration ceases.
