established requirements for reporting any
system defects, unusual and excessive opera-

crew will also make entries on DA Form
2408-13 to indicate when limits in the Oper-

This aircraft is qualified for operation in instru-
ment meteorological conditions. Flight handling,
stability characteristics and range are approximately
the same during instrument flight conditions as
when under visual flight conditions.
tion the flight director pitch steering bar. Retract
flaps after attaining best single-engine rate-of-climb
speed (V yse), and re-adjust pitch as required. Control
bank attitude to maintain the desired heading. Sup-
port flight director indications throughout the
maneuver by crosschecking raw data information
displayed on supporting instruments.
8-55. INSTRUMENT FLIGHT PROCEDURES.
Refer to FM 1-5, FM 1-230; FLIP; AR 95-1; FC
1-2 18; or applicable foreign government regulations,
and procedures described in this manual.
8-56. INSTRUMENT TAKEOFF.
Complete the BEFORE TAKEOFF check.
Engage the heading (HDG) mode on the autopilot
computer/control (do not engage autopilot). Set
heading marker (HDG) to runway heading and align
the aircraft with the runway centerline, insuring that
nosewheel is straight before stopping aircraft. Hold
brakes and complete the LINEUP check. Insure that
the roll steering bar is centered. Power application
and copilot 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 refer-
ences. As the takeoff progresses, the crosscheck
should transition from outside references to the
flight director and airspeed indicator. The rate of
transition is directly proportional to the rate at
which the outside references deteriorate. Approach-
ing rotation speed (V,), the crosscheck should be
totally committed to the instruments so that errone-
ous sensory inputs can be ignored. At rotation
speed, establish takeoff attitude on the flight direc-
tor. Maintain this pitch attitude and wings-level atti-
tude 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 best rate-of-climb air-
speed (V,). Use PITCH-SYNC as required to reposi-
Due to possible precession error, the pitch
steering bar may lower slightly during
acceleration, causing the pitch attitude to
appear higher than actual pitch attitude.
To avoid lowering the nose prematurely,
crosscheck the vertical-velocity indicator
and altimeter to insure proper climb per-
formance. The erection system will auto-
matically remove the error after the accel-
8-57. INSTRUMENT CLIMB.
Instrument climb procedures are the same as
those for visual climb. Enroute instrument climbs
are normally performed at cruise climb airspeeds.
8-58. INSTRUMENT CRUISE.
There are no unusual flight characteristics dur-
ing cruise in instrument meteorological conditions.
8-59. INSTRUMENT DESCENT.
When a descent at slower than recommended
speed is desired, slow the aircraft to the desired
speed before initiating the descent. Normal descent
to approach altitude can be made using cruise air-
speed. Normally, descent will be made with the air-
craft in a cruise configuration, maintaining desired
speed as required.
