Vmeto, whichever is greater unless obstacles are a factor. WARNING: Max effort
operations at high altitude, gross weight, and temperatures are critical; climb angles as
low as 2.5 degrees may prevent the aircraft from accelerating. Any further climb angle
increase may result in the loss of airspeed and the onset of a pre-stall buffet.
5.18.8. Anti-icing fluid. AMS 1428, Type II and IV anti-icing fluid is authorized for use in
extreme climatic conditions. Due to the shearing properties of Type II/IV anti-icing fluid, it
may be necessary to increase takeoff speed. When Type II/IV anti-icing fluid is used,
increase takeoff speed to a minimum of 110 KIAS and make necessary distance corrections
to performance data. Also reference paragraph 6.21.2
5.19. Aircraft Taxi and Taxi Obstruction Clearance Criteria and Foreign Object Damage
(FOD) Avoidance.
5.19.1. Do not taxi an aircraft within 25 feet of obstructions without wing walkers
monitoring the clearance between aircraft and obstruction. With wing walkers, avoid taxi
obstructions by at least 10 feet. EXCEPTION: IAW AFI 11-218, aircraft may taxi without
marshallers/wing walkers at home station along fixed taxi lines which have been measured to
ensure a minimum of 10 feet clearance from any obstruction and the obstruction is
permanent. Adjacent aircraft are also considered a permanent obstruction, provided the
aircraft is parked properly in its designated spot and is not moving. Aerospace Ground
Equipment (AGE) and vehicles are considered a permanent obstruction, provided it is parked
entirely within a designated area. Areas will be designated by permanent markings such as
painted boxes or lines on the ramp or another suitable means.
5.19.2. When taxi clearance is doubtful, use one or more wing walkers. If wing walkers are
unavailable, deplane one or more crewmembers to maintain obstruction clearance and
provide marshalling using AFI 11-218 signals. Use wing walkers, deplaned crewmembers,
or a crewmember on interphone positioned at the paratroop door(s) to act as an observer
while maneuvering on narrow taxiways. During night taxi operations, marshallers will have
an illuminated wand in each hand. Wing walkers are only required to have one illuminated
wand. Observers will be in a position to see wing walkers at all times (through door or
windows) and communicate with the pilot.
5.19.3. FOD Avoidance. Make every effort to minimize the potential for engine FOD.
Crews should:
5.19.3.1. Carefully review airfield layout paying particular attention to taxi routes, turn
requirements, and areas for potential FOD.
5.19.3.2. Minimize power settings during all taxi operations.
5.19.3.3. Use low speed ground idle whenever possible.
5.19.3.4. Where possible, avoid 180° turns. If it becomes necessary to accomplish a
180° turn on a narrow runway, the turn should be accomplished at an intersection of a
link taxiway or at a designated turn around pad.
5.19.3.5. Where possible, avoid taxi operations that position an engine over an
unprepared or un-swept surface. If unavoidable, leave the engine in idle (to the
maximum extent possible) until the engine is over an improved surface.
