Alternate aerodrome types
Alternate aerodrome: aerodrome you may proceed to when proceeding to, or landing at, the aerodrome of intended landing is impossible or inadvisable.
| Kind | Purpose |
|---|---|
| Takeoff alternate | Landing shortly after takeoff, when departure aerodrome can't be used |
| En-route alternate | Abnormal or emergency condition arising while en route |
| Destination alternate | Named in flight plan; intended destination impossible or inadvisable |
- Departure aerodrome can be its own flight's en-route or destination alternate, not automatically: must meet landing conditions at the time.
Trap: treating departure aerodrome as automatic alternate for its own flight.
