(1) (d) ~ The Descent Phase
The flight phase changes to descent once ASEL ARM towards a
lower preselector altitude is detected, unless a
cruise-descent is flown.
After leveling off, while in
descent, the flight phase will change back to cruise, if the
level segment is predicted to be at least 100 NM (see
Figures 270.5 and 270.6).
Typically, the level segments are
shorter, and the flight phase stays in descent all the way
down.
Once in descent, the flight phase can go back to climb if a
climb is initiated (see Figure 270.7).
If
a missed approach is executed (see Figure 270.8), the
flight phase transitions to climb. A new cruise altitude is
defined at the preselector altitude, and a short
cruise-segment will be flown before flight phase transitions
to descent.
~ The Auto EPR Rating Transitions
The auto EPR rating is set to TO on the ground. FLEX is
also boxed if selected on the TAKEOFF INIT pages.
As long
as the flight guidance computer (FGC) mode is TO the auto
EPR rating will remain TO as well. The TO rating will be
kept until passing 400 ft. above the field elevation under
all circumstances.
