Sid....no matter you used a fourth name....the concept is the same.
Using your figure of 90 Kgs "Minimum Landing Allowance"....is it safe to say had that mandate to Land upon reaching the MLA Fuel level been complied with, we would not be having this discussion extant?
How far into the Supply Tanks would that be?
Did the aircraft over fly or fly by locations a safe landing could have been made, and should have been made respective to the MLA Fuel Requirement?
Does NPAS take disciplinary action when Pilots land with less than MLA Fuel?
Better question is does NPAS take Disciplinary Action (even unofficial action) if a Pilot makes a precautionary landing due to lack of fuel?
