Descent Forecast Page
The descent forecast page is used for pre–descent planning to enter forecast data
for more precise descent path calculation.
The primary entries are wind direction and speed for up to three descent altitudes,
and the altitude that anti–icing is turned on and off.
1
Transition Level (TRANS LVL)
Normally displays FL180 as the assumed descent transition level.
Changes automatically when entering flight plan data based on the following
criteria if a pilot entered value has not already been entered:
• the FMC will use the transition level from the NDB stored for the STAR
or terminal approach record if the flight plan is active, a STAR or
terminal approach has been selected and the transition level exists for
the STAR.
• if an active flight plan exists and no transition level exists on the STAR
or terminal approach NDB record or a STAR or terminal approach has
not been selected, then the FMC will use the transition level from the
NDB stored for the DESTINATION airport.
