• if there is no trans level for the DESTINATION airport in the NDB for
the conditions defined above, then the default transition level will
default to the transition altitude from the NDB stored for the
DESTINATION airport.
• if the transition level is not available from any of the sources above,
then the FMC will default the transition level to 18000 feet or the value
contained in a loaded custom performance defaults data base.
Manual entry allowed and takes priority.
Data may be up-linked via ACARS message. The up-linked value will appear in
small font until EXECuted at which time it will be displayed in large font.

CABIN RATE
Displays the predicted cabin rate of descent required by the active flight plan
descent profile.
3
Descent Wind (ALT – – – – – WIND – – – – DIR/SPD)

values.
Entries may be made in any altitude sequence and will be automatically ordered
by altitude from highest to lowest.
Data may be up-linked via ACARS message. The up-linked value will appear in

Data may be up-linked via ACARS message. The up-linked value will appear in
small font until EXECuted at which time it will be displayed in large font.
5

Enter the destination QNH altimeter setting (IN. HG. or MB). Do not enter a QFE
altimeter setting.
Data may be up-linked via ACARS message. The up-linked value will appear in
small font until EXECuted at which time it will be displayed in large font.
