Lateral Revisions

The flight crew may revise the lateral flight in 3 ways:

Insert or delete a waypoint

Use a Direct To

Create a temporary flight plan

Inserting/Deleting a waypoint

The flight crew may select the DIRECT TO MCDU page using the MCDU direct page keys. This DIRECT TO page allows the flight crew to select a waypoint (from the flight plan or otherwise ) to be used as the TO waypoint.

Direct To

The fight crew may modify/enter/delete several waypoints of an airway at once. The resulting modification is a temporary flight plan which is shown in dashed amber color on the ND. The temporary flight plan may then be inserted or deleted. Insertion makes the temporary modification permanent for the flight.
