Climb Calculations
During performance initialization, the pilot is required to
accept the default climb mode or select the desired climb mode.
This is the mode
used
for the flight planning function.
However, each climb mode is available
for selection at any
time. For the active climb mode, the performance computer
calculates and displays the following climb parameters:
. Top-of-climb (TOC) altitude
Estimated time enroute (ETE) and estimated time-of-arrival
(ETA) at the TOC altitude
. Command speed
. Distance-to-go (DTG) to the TOC altitude
. Command engine pressure ratio (EPR) setting
. Current fuel remaining
(e) Cruise Calculations
While in the cruise mode, the performance function calculates
speed and recommended power settings. The autothrottle
controls speed of the aircraft. Altitude is flown by the
flight control system on the elevator. The following
parameters are calculated and/or displayed on the CDU cruise
pages for the active cruise modes: " -
. Cruise altitude*
c Optimum altitude
Step altitude (based on initialized step alt"
c Command speed
ETE and ETA to step climb point
. Command EPR setting
tude increment)
c DTG for step point
. Range to reserve
Time to reserve
. Current fuel remaining
* Cruise altitude is the higher of the entered cruise
altitude or the preselect-altitude until matched by actual
altitude.
