Reading a few of these posts, has been a frightening experience.
Try flying around parts of Africa with those sort of reserves and you may come unstuck very quickly indeed.
It amuses me when an alternate is chosen depending on weather. What if an a/c lands, burst the tires and the runway is closed. Then where will you go?
One outfit used to fly into Khartoum years ago the closest alternate then was Jeddah, so commercial pressure took over and they amended the arrival fuel to "Island" hold!! What a lot of BS.
The legal minimum fuel quiet often is not enough, in the 3rd world, very often it is not enough.
