Fuel Gravity Feeding
Hi, i want to know why do I have to descent below an specific altitude when a gravity fuel feeding is to be performed, what happens to fuel at higher altutudes and how this afects the gravity feeding?

Depending on the fuel it might boil at altitude - some helicopters have fuel boost pumps for this reason to prevent cavitation. If they fail, most flight manuals state that you have to descend below 6 000 feet. Probably not so much a factor with modern fuels, but still something to be aware of.
