Definition
A flight planning procedure used by air carriers on long-range flights in which the airplane is initially dispatched to a planned intermediate point with required fuel reserves, then re-released (redispatched) in flight to continue to the original destination once fuel state and conditions are confirmed adequate. This allows the flight to depart with less total fuel than would otherwise be required by regulations for the full route.
Plain English
A method where a long flight is officially planned to a closer point first, then given a new clearance in the air to continue all the way to the real destination. It lets the airline carry less fuel at takeoff while still meeting safety rules.
Context Anchor
Seen in airline and commercial flight planning, especially on longer flights where fuel planning and destination weather must be checked again after departure.
Derivation
From 'dispatch' (to send off on official business, from Italian 'dispacciare,' to send away) with the prefix 're-' meaning 'again.' So redispatch literally means 'sent off again' — the flight is released a second time, in the air, to its final destination.
Why Pilots Care
It gives crews and dispatchers the flexibility to select a better destination for safety or efficiency without creating a new regulatory violation.
Intuition Check
Redispatch does not mean the airplane lands and starts over. It means the flight’s official release is reviewed and changed while the airplane is already en route.
Example Sentence 1
The crew confirmed they had the required fuel at the redispatch point and received clearance to continue to their original destination.
Example Sentence 2
After the weather improved at the alternate, ATC approved the redispatch and the crew continued to the new airport.
