OAT - Outside air temperature is boxed indicating a mandatory entry for V-speed
computations. Entries may be preceded by a + or - for temperature, otherwise +
will be the default. Entries may be made in either degrees Centigrade or
Fahrenheit. C for Centigrade or F for Fahrenheit must follow the temperature
entered. After the temperature is entered, pushing 3R with no data in the SP will
cause the OAT entry to be converted between Centigrade and Fahrenheit values.
NOTE: Temperature for the FMS OAT must not be taken from the TAT
display on the EAD. Another source such as ATIS, ATC, weather
dispatch, etc., must be used.
Line 4R CLB THRUST, Line 5R ACCEL and Line 6R EO ACCEL are computed
by FMS and may be altered by the pilot during preflight. If the computed values
are not available, the pilot is allowed to enter values into the dashed fields.
NOTES: With the FCP altitude set lower than the ACCEL or CLB
THRUST altitude, the FMS values will be edited to the FCP altitude
during altitude capture. Provided all engines are operational, climb
speed (VCL), limited by constraints and placard speeds, will become
the FMS speed target and climb thrust (CLB THRUST) will become
the engine thrust setting when the aircraft levels off at the FCP
altitude (ALT HOLD).
If the aircraft has not climbed through the ACCEL altitude and flaps
and slats are extended, the Vmin marker on the airspeed display will
be a function of 1.2 Vs.
The takeoff speeds (V1, VR, V2) computed by the FMS are based on
Balanced Takeoff Performance as computed in the Airplane Flight
Manual (AFM)
