Alternate Aerodrome

[Ref Jeppesen]

What’s Alternate?

Alternate aerodrome is/are somewhere an aircraft may proceed when the aerodrome of intended landing (planned destination) becomes either impossible or inadvisable to proceed to or to land at.

(4) main types of alternate aerodromes:

  1. Take-Off Alternate — An alternate aerodrome at which an aircraft can land should this become necessary shortly after take-off and it is not possible to use the aerodrome of departure.
  2. En Route Alternate—An aerodrome at which an aircraft would be able to land after experiencing an abnormal or emergency condition while en route.
  3. Destination Alternate—An alternate aerodrome to which an aircraft may proceed should it become
    impossible or inadvisable to land at the aerodrome of intended landing.
    NOTE: The aerodrome from which a flight departs may also be an en route or a destination alternate aerodrome for that flight.
  4. ETOPS En Route Alternate — A suitable and appropriate alternate aerodrome at which an aeroplane would be able to land after experiencing an engine shutdown or other abnormal or emergency condition while en route in an ETOPS operation.
