SPO.OP.105Specification of isolated aerodromes – aeroplanes

For the selection of alternate aerodromes and the fuel/energy planning and in-flight re-planning policy, the operator shall not consider an aerodrome as an isolated aerodrome unless the flying time to the nearest weather-permissible destination alternate aerodrome is more than:

(a)for aeroplanes with reciprocating engines, 60 minutes; or

(b)for turbine-engined aeroplanes, 90 minutes.

Show the text

USE OF AN AERODROME AS AN ISOLATED AERODROME The concept of an isolated aerodrome allows the operator to use aerodromes that would otherwise be impossible or impractical to use with sufficient fuel to fly to the destination aerodrome and then to a destination alternate aerodrome, provided that operational criteria are used to ensure a safelanding option, for example by specifying a point of no return (PNR). If alternate fuel is carried, the operator is not required to consider the aerodrome as isolated and use the aforementioned operational criteria.
