TRANS ALT [1L]:
When a modification is made to the origin airport or associated departure procedure, this
field will be updated to show the navigation database extracted value, if one exists, otherwise the FMS default
value will be displayed.
The valid enterable range for this field is 0 to 450 or 1000 to 45000.
NOTE: if a value between 0 and 450, inclusive, is entered, it will be converted and shown as a transition
altitude in feet.
Entering DELETE on this field, when a manually entered value had previously been entered, will restore this
field to the navigation database extracted value or to the FMS default. Deletion of the default value or navigation
database values is inhibited.
Crew entries will not be erased by a new value extracted from the navigation database as a result of the latest
flight plan modifications. However, if this new extracted value is different from the crew entered value, the FMS
will generate the TRANS ALT/LVL MISMATCH message.
The FMS will also generate the CHECK TRANS/ALT LVL status advisory message if there is no value in the
navigation database for the selected origin and/or associated departure procedure(s) and no manual crew entry
exists to the TRANS ALT field at the moment the flight plan is executed.
NOTE: The TRANS ALT value defines the altitude at which the crew should change from local pressure
altimeter setting to standard pressure altimeter setting. The TRANS ALT value is used in triggering the
SET QNH message.
TRANS LVL [2L]:
When a modification is made to the destination airport or associated arrival procedure, this
field will be update to show the navigation database extracted value, if one exists, otherwise the FMS default
value (as configured) will be displayed.
The valid enterable range for this field is 0 to 450 or 1000 to 45000.
NOTE: If a value between 1000 and 45000, inclusive, is entered, it will be converted and shown as a transition
level in Flight Level units.
Entering DELETE on this field, when a manually entered value had previously been entered, will restore this
field to the navigation database extracted value or to the FMS default. Deletion of the default value or navigation
database values is prohibited.
Crew entries will not be erased by a new value extracted from the navigation database as a result of the latest
flight plan modifications. However, if this new extracted value is different from the crew entered value, the FMS
will generate the TRANS ALT/LVL MISMATCH message.
The FMS will also generate the CHECK TRANS/ALT LVL status advisory message if there is no value in the
navigation database for the selected destination and/or associated arrival/approach procedure(s) and no manual
crew entry exists to the TRANS LVL at the moment the flight plan is executed.
If tactical approach is configured, the CHECK TRANS/ALT LVL status advisory message is generated when
making the inactive route containing a tactical approach into the now active route.
Also, if tactical approach is configured, this field is identical and shared with the TRANS LVL field seen on the
TACTICAL APPR page.
NOTE: The TRANS LVL value defines the altitude at which the crew should change from standard pressure
altimeter setting to local pressure altimeter setting. The TRANS LVL value is used in triggering the SET
QNH message.
