“An aircraft's fuel system has a more
profound effect on aircraft performance than
any other airframe system. Without fuel, the
mission inevitably comes to an abrupt stop
and, unless the flight crew is very, very lucky,
the ensuing forced landing will cause severe
or catastrophic aircraft damage.” ~ Fred

4. Typical Fuel Tanks
Integral
Rigid Removable
Bladder
Rule of Thumb for max. fuel volume: 85% for wing
tanks and 92% for fuselage tanks, measured to the
external skin surface (exception: bladder tanks, 77%
and 83%, respectively)
External
5. Components
Main Tanks
Header Tank (separate from main tanks, holds
enough fuel for engines to run during
complicated maneuvers)
Gravity Feed (small aircraft only)
Electric/Engine-driven Fuel Pumps
7. Fuel Dumping Systems
Needed to meet landing weight limits of
landing gear or runway length
System of fuel pumps and valves
Usually ejected from wingtips
Sometimes from aft-most point of fuselage
Usually designed to allow the plane to go
from max take-off weight to max landing
weight in 15 minutes or less.
10. In-Flight Refueling
Original motivation: endurance records
Currently used only in the military sector
Two main types:
Boom and Receptacle
Probe and Drogue
