APPROACH page may be accessed from line 6R.
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 Vstall. If the slats are retracted prior to reaching
the ACCEL altitude, the Vmin marker will be a function of 1.25
Vstall. Once the ACCEL altitude has been achieved, the Vmin
marker will be a function of 1.3 Vstall.
THRUST LIMITS PAGE
Access to the THRUST LIMITS page is available from the TAKEOFF page,
active PERF page, and the GO AROUND page.
The THRUST LIMITS page allows selection of maximum as well as preselected
derated thrust limits. The THRUST LIMITS function allows for two THRUST
LIMIT modes: AUTO and MANUAL. In AUTO mode, the FMC performs all
automatic thrust limit transitions based on the aircraft state in the vertical flight
plan. In MANUAL mode, the flight crew causes thrust limit transitions by manual
selection on the THRUST LIMITS page and the only automatic transitions
performed by the FMCs are aircraft safety related.
AUTO is the default selection mode at power up or in preflight. MANUAL mode
is activated by selecting any thrust limit displayed in large font.
NOTE: The thrusts selected on this page merely set thrust limits; they do
not control the thrust required.
Through the course of a flight one thrust limit is always ACTIVE while all others
are either AVAILABLE FOR ACTIVATION, ARMED, or AVAILABLE FOR
ARMING. The ACTIVE thrust limit is sent to the FCC for throttle control. This
is the limit displayed on the left side of the page in large font, preceded by a right
arrow.
NOTE: The pilot can change the ACTIVE thrust limit any time prior to
takeoff by pushing the line select key (LSK) corresponding to an
AVAILABLE FOR ACTIVATION takeoff thrust limit (one with an
asterisk).
