LAT REV AND NEW DEST: DIVERSION FROM A DEFINED REVISE POINT
NEW DEST changes the primary destination from a selected revise point. It is different from entering an alternate airport and different again from activating a prepared secondary route. In the source standard, the original legs after the revise point are removed and a new route to the replacement destination must be established. The chosen revise point is therefore a major part of the command. [66, PDF pp. 308-311,328,279-284]
1. Choose the operational branch. If the intended diversion already exists as a reviewed alternate route or secondary plan, inspect that prepared option first. If the route is being built afresh, identify where the clearance leaves the current route. Use that actual fix for LAT REV. A present-position diversion requires a present-position/direct or appropriate intercept solution, not a future fix selected merely because it is visible. [66, PDF pp. 308-311,328,279-284]
2. Enter the new destination. In LAT REV, use NEW DEST and enter the verified airport identifier. EGKK can illustrate the alternate-destination branch of our teaching case only when that is the intended exercise. Read the temporary plan's new destination and the retained route up to the revise point. Then inspect what has disappeared after that point. [66, PDF pp. 308-311,328,279-284]
3. Construct the new route. Enter the cleared connecting fixes, airways and arrival as appropriate, resolving intentional gaps and vectors. A destination identifier alone does not create the route clearance. Review the resulting geometry from the actual aircraft position through the retained segment and new continuation. Check that no convenient direct connection has silently replaced a required route. [66, PDF pp. 308-311,328,279-284]
4. Rebuild destination-dependent preparation. Reconcile approach/radio selection, destination weather, minima, landing configuration, performance and predicted fuel. Read the cruise/phase reference after the change instead of accepting a default as the desired clearance. Some destination-dependent wind information can be removed or altered in the source standard. The revised flight needs a complete current arrival context. [66, PDF pp. 308-311,328,279-284]
5. Insert and inspect the working flight. Verify the active FROM/TO, destination and first intended leg, then read the FMA and selected targets. Review the new time/fuel picture against the actual route and remaining fuel. Company notification, ATC coordination and route modification are separate tasks; completing a NEW DEST entry does not establish that either external party has received or approved the change.
