Dry runway landing performance is shown for max manual braking
configuration and autobrake settings max, 3, 2, and 1. The autobrake
performance may be used to assist in the selection of the most desirable
autobrake setting for a given field length. Selection of an autobrake setting
results in a constant rate of deceleration. Maximum effort manual braking
should achieve shorter landing distance than the max autobrake setting.
The reference landing distance is a reference distance from 50 ft above the
threshold to stop based on a reference landing weight and normal approach
speed for the selected landing flap at sea level, zero wind, zero slope, and
two engine detent reverse thrust. Subsequent columns provide adjustments
for off-reference landing weight, altitude, wind, slope, temperature, speed,
and reverse thrust. Each adjustment is independently added to the
reference landing distance.
Non-normal Configuration Landing Distance
Advisory information is provided to support non-normal configurations
that affect the landing performance of the airplane. Landing distances and
adjustments are provided for dry runways and runways with good,
medium, and poor reported braking action.
Enter the table with the applicable non-normal configuration and read the
normal approach speed. The reference landing distance is a reference
distance from 50 ft above the threshold to stop based on a reference landing
weight and speed at sea level, zero wind, and zero slope. Subsequent
columns provide adjustments for off-reference landing weight, altitude,
wind, slope, and speed conditions. Each adjustment is independently added
to the reference landing distance. Landing distance includes the effect of
reverse thrust.
Recommended Brake Cooling Schedule
Advisory information is provided to assist in avoiding the problems
associated with hot brakes. For normal operation, most landings are at
weights below the AFM quick turnaround limit weight.
Use of the recommended cooling schedule will help avoid brake overheat
and fuse plug problems that could result from repeated landings at short
time intervals or a rejected takeoff.
