BOAC I'm not comcerned about contingency. But Does it work?
My concern is what happens after those 25 minutes and I shoot off to the alternate. Mind you I'm talking about a planning perspective here, in the air all that counts is landing with final reserve. So simply planning:
As you can see 2 of the 3FR aircraft diverted well above final reserve + alternate was reached. They didn't do a go-around so that saved some fuel as well. But they all had to declare a mayday to land with final reserve. Ergo to me it seems their alternate fuel was insufficient.
Or should it be expected to immediately declare a mayday once you elect to divert at final reserve + alternate?
Is it normal that any delay will lead to a mayday, or is our alternate fuel being planned too tight.
