Brake temperature indications on Multifunction Display are also shown.
The hottest brake indication 10 to 15 minutes after the airplane has come
to a complete stop, or inflight with gear retracted, may be used to
determine recommended cooling schedule by entering at the bottom of the
chart. An EICAS advisory message, BRAKE TEMP, will appear when any
brake registers 5.0 or higher on the EICAS indication and disappear as the
hottest brake cools with an EICAS indication of 3.5. Note that even
without an EICAS advisory message, brake cooling is recommended.
Landing Climb Limit Weight
In the event an overweight landing is necessary and the fuel dump system
is unavailable, landing climb limits should be checked if a Flaps 25 or 30
landing is planned. Enter the table with airport OAT and pressure altitude
to read landing climb limit weight. Apply the noted adjustments as
required. At weights exceeding those shown, plan a Flaps 20 landing.
Fuel Heating Schedule
To Be Supplied.
Engine Inoperative
Initial Max Continuous TPR
The Initial Max Continuous TPR setting for use following an engine failure
is shown. The table is based on the typical all engine cruise Mach number
of .85 to provide a target TPR setting at the start of driftdown. Once
driftdown is established, the Max Continuous TPR table should be used to
determine TPR for the given conditions.
Max Continuous TPR
Power setting is based on one engine operating with anti-ice on or off.
Enter the table with pressure altitude and IAS or Mach to read TPR.
It is desirable to maintain engine thrust level within the limits of the Max
Cruise thrust rating. However, where thrust level in excess of Max Cruise
rating is required, such as for meeting terrain clearance, ATC altitude
assignments, or to attain maximum range capability, it is permissible to use
the thrust needed up to the Max Continuous thrust rating. The Max
Continuous thrust rating is intended primarily for emergency use at the
discretion of the pilot and is the maximum thrust that may be used
continuously.
