State requirements for takeoff alternates on non-ETOPS and ETOPS flights
Non-ETOPS: takeoff alternate must be located within 407NM (60 min diversion distance at nominated nil wind single engine speed VMO) with forecast conditions above landing minima.
ETOPS: takeoff alternate above ETOPS dispatch weather minima must be within 1200nm (180 minute diversion distance established at 310kias, 210t)
State Destination alternate planning requirements
At least one alternate shall be planned unless the destination is an isolated airfield.
When is a destination considered an isolated airfield?
- if the fuel required (alternate + FFR) to the nearest destination alternate airfield is more than two hours at normal cruise consumption
- if forecast weather conditions at the isolated airfield are at or above alternate weather minimum from 30 mins before ETA to 2 hours after ETA. Inter and tempo deteriorations do not need to be considered.
State the En route alternate airfield requirements for Non-ETOPS and ETOPS flights
Non-ETOPS: must remain within 407nm (60min) of en route alternate airfields where forecast weather conditions are above applicable airfield landing minima.
ETOPS: must remain within 1200nm (180 mins) of adequate airfields that meet ETOPS dispatch weather minima as contained within SI(OPS) 03-156
