Take Off Alternates Rules
 

Take Off Alternates Rules: Anyone know off the top of their heads what the JAR Ops rules are for 3/4 engine aircraft are in respect of Dist./Time? Or I'd be grateful for a link; I'm stuck in a hotel room down route.

JAR-OPS 1.295:

(b) An operator must select and specify in the operational flight plan a take-off alternate if it would not be possible to return to the aerodrome of departure for meteorological or performance reasons. The take-off alternate shall be located within:

(1) For two-engined aeroplanes, either:

(i) [snip]

(ii) [snip]

(2) Two hours flight time at a one engine-inoperative cruising speed according to the AFM in still air standard conditions based on the actual take-off mass for three and four engined aeroplanes; and

(3) If the AFM does not contain a one engine-inoperative cruising speed, the speed to be used for calculation must be that which is
achieved with the remaining engine(s) set at maximum continuous power.

Hope that's what you wanted.

Thanks Dexter, a thousand blessings on all your goats/camels/wives, whatever applies!
