Tables for Non-Normal Configuration Landing Distance in this section are
similar in format and used in the same manner as tables for the Normal
Configuration Landing Distance previously described.
For an engine inoperative landing, check the rate of climb capability
shown in Gear Down Landing Rate of Climb Available tables to ensure
adequate climb performance.
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 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.
Enter the Reference Brake Energy table (Table 1) with the airplane weight
and brakes on speed, adjusted for wind, at the appropriate temperature and
altitude condition. Instructions for applying wind adjustments are included
below the table. Linear interpolation may be used to obtain intermediate
values. The resulting number is the reference brake energy per brake in
millions of foot-pounds, and represents the amount of energy absorbed by
each brake during a rejected takeoff.
To determine the energy per brake absorbed during landing, enter the Event
Adjusted Brake Energy table (Table 2) for no reverse thrust or 2 engine
reverse thrust with the reference brake energy per brake and the type of
braking used during landing (Max Manual, Max Auto, or Autobrake). The
resulting number is the adjusted brake energy per brake and represents the
energy absorbed in each brake during the landing. The recommended
cooling time is found in the final table (Table 3) by entering with the
adjusted brake energy per brake. Times are provided for ground cooling
and inflight gear down cooling.
Brake Temperature Monitor System (BTMS) indications are also shown. If
brake cooling is determined from the BTMS, use the hottest brake
indication 10 to 15 minutes after the airplane has come to a complete stop,
or inflight with gear retracted to determine recommended cooling
schedule.
