TM 55-1510-221-10
Section IV. LOADING LIMITS
5-17. CENTER OF GRAVITY LIMITATIONS.
Center of gravity limits and instructions for
computation of the center of gravity are contained
in Chapter 6. The center of gravity range will remain
within limits, providing the aircraft loading is
accomplished according to instructions in Chapter 6.
The ability to sustain loss of engine power
and successfully stop, continue the take-
off, or climb before or after gear retrac-
tion is not assured for all conditions.
Thorough mission planning must be
accomplished prior to takeoff by analysis
of maximum takeoff weight permitted by
takeoff distance, accelerate-stop, positive
one-engine-inoperative climb at lift off,
accelerate-go, takeoff climb gradient, and
climb performance. These data will
describe performance capabilities for crit-
ical mission decisions.
5-18. WEIGHT LIMITATIONS.
Maximum takeoff gross weight is 15,000
pounds. Maximum landing weight is 15,000 pounds.
Maximum ramp weight is 15,090 pounds. Maxi-
mum zero fuel weight is 11,500 pounds.
Section V.
AIRSPEED LIMITS, MAXIMUM AND MINIMUM
5-19. AIRSPEED LIMITATIONS.
5-23. WING FLAP EXTENSION SPEEDS.
Airspeed indicator readings contained in proce-
dures, text, and illustrations throughout this Opera-
tor’s Manual are given as indicated airspeed (IAS).
Airspeed indicator markings (fig. 5-1) and placarded
airspeeds, located on the cockpit overhead control
panel (fig. 2- 12), are also indicated airspeeds.
The airspeed limit for APPROACH extension
(40%) of the wing flaps is 198 KIAS. The airspeed
limit for full DOWN extension (100%) of the wing
flaps is 153 KIAS. If wing flaps are extended above
these speeds, the flaps or their operating mecha-
nisms may be damaged.
5-20. MAXIMUM ALLOWABLE AIRSPEED.
The maximum allowable airspeed is 243 KIAS/
0.42 Mach.
5-24. MINIMUM SINGLE-ENGINE CONTROL AIR-
SPEED (Vmc ).
5-21. LANDING GEAR EXTENSION SPEED.
The airspeed limit for extending the landing gear
and for flight with the landing gear extended is 180
KIAS.
Chapter 7, Section X describes minimum single-
engine control airspeeds. The minimum single-
engine control airspeed (Vmc ) at sea level standard
conditions is 91 KIAS.
5-22. LANDING GEAR RETRACTION SPEED.
5-25. MAXIMUM
DESIGN
MANEUVERING
SPEED.
The airspeed limit for retracting the landing gear
is 162 KIAS.
The maximum design maneuvering speed is 168
KIAS.
