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
max manual braking and reverse thrust.
Recommended Brake Cooling Schedule
Advisory information is provided to assist in avoiding problems associated
with hot brakes. For normal operation, most landings are at weights below
the quick turnaround limit weight. Application of the recommended
cooling procedures shown will avoid brake overheat and fuse plug
problems that could result from repeated landings at short time intervals or
a rejected takeoff.
Engine Inoperative
Initial Max Continuous %N1
The Initial Max Continuous %N1 setting for use following an engine
failure is shown. The table is based on the typical all engine cruise speed
of .74M to provide a target %N1 setting at the start of driftdown. Once
driftdown is established, the Max Continuous %N1 Table should be used
to determine %N1 for the given conditions.
Max Continuous %N1
Power setting is based on one engine operating with one A/C pack
operating and all anti-ice bleeds off. Enter the table with pressure altitude
and IAS or Mach to read %N1.
