2. Lateral revisions that lead to a temporary flight plan (TMPY) before they take effect:
The flight crew creates a temporary flight plan then inserts it as a revision to the active flight plan.
The flight crew does this when selecting, deleting, or modifying several waypoints of an airway or
procedure at once (SID, STAR, HOLD, TAKEOFF or LANDING RWY). This modification is made
on specific “LAT REV” pages from the flight plan page.
Possible revisions are:
Insert or modify departure procedure‐
Insert or modify arrival procedure‐
Insert a waypoint‐
Change the destination‐
Insert an airway‐
Insert an offset‐
Insert a holding pattern‐
Select or enable an alternate flight plan‐
Fix information.‐
The purpose of the temporary flight plan is to allow the flight crew to review the revision on the
MCDU and on the ND before inserting it into the active flight plan.
It is a copy of the active flight plan that has been changed according to the flight crew revision.
While it is displayed, the aircraft will continue to follow the original active flight plan.
No predictions are computed or displayed on the pages of the temporary flight plan.

FMS LEGACY
GENERAL
Applicable to: ,
The lateral revision function allows the pilot to create or modify the following parts of the flight plan :
airway‐
waypoint‐
new destination‐
holding pattern‐
offset‐
alternate‐
Fix information‐
Each time the pilot activates one of the revisions listed above, he accesses to a temporary flight
plan that allows to check the modification before inserting it in the active flight plan. The crew
selects these functions by pressing the left keys on F-PLN A or B.
Direct to and overfly functions are accessed through MCDU keys. No temporary flight plan is‐
created with these functions.
“Update at” capability is a specific function that manually updates the FM position. It does not use‐
a temporary flight plan, but the pilot must confirm the insertion before it is activated.
TEMPORARY F-PLN (TMPY)
Applicable to: ,
When a pilot makes a lateral revision to the F-PLN, the FMGS creates a temporary flight plan. This is
a copy of the active F-PLN, but is corrected by the lateral revision in progress.
The aircraft continues to follow the active F-PLN until the temporary revision is inserted.
The revision appears in yellow characters on both MCDUs and NDs.
Lateral and vertical revisions cannot be made to a temporary F‐-PLN.
Only one temporary F‐-PLN may be accessed at a time.
The “DIRECT TO” function, when used, erases a temporary F‐-PLN.
When a DIR TO is in process, a temporary revision cannot be displ‐ayed on the other MCDU.
A TMPY F‐-PLN changes the title of the flight plan pages. (TMPY appears in all titles).
No predictions are computed for a temporary flight plan (Dashes are displayed).‐
