I wonder if someone with experience of flying in France (or anywhere else in Europe) can explain how they calculate their safety altitude from a given MEF on a flight chart.
I am involved in a military project trying to define a SALT corridor within an FMS. The french civilian FTE reckons the French do not have a stepped margin eg RAF rules 0-3000ft, add 1000ft, 3001+ add 2000ft but rather they just have one value for all terrain. In true French-British fashion I don't believe him
as it seems weird that the UK (Mil and Civilian), US and Canadians all have stepped values and they (the French) don't.
Can anyone shed any light on this matter or point me in the direction of somewhere I can find the EASA (or national) regs for this?
Regards
