Fuel Flashcards
Specific Range Formula
( TAS / Fuel Flow )
OR
( Cruise NAM / Fuel Consumption )
NAM formulas
( TAS / Groundspeed ) = ( NAM / NGM )
OR
( NAM / TAS ) = ( NGM / Groundspeed )
Explain the Point of Equal Time/Critical Point
The point at which it will take just as long to return to the point of departure as it will to carry on to the destination
PET Formula
( Total Distance x Return Groundspeed ) / ( Onward Groundspeed + Return Groundspeed )
Explain what the Point of Safe Return is
The furthest point you can fly to and then return to a landing point behind you, based on a given amount of fuel.
The PSR is a ___ problem
endurance/fuel
The CP/PET is not a ___ problem
fuel
PSR Formula
( Safe Endurance / Return Groundspeed ) / ( Onward Groundspeed + Return Groundspeed )
