Study Notes
Fuel Tank Vent System Purpose
- Prevents overpressure and underpressure in fuel tanks.
- Allows air to escape during refueling.
- Allows air to enter during flight as fuel is consumed.
Vent Surge Tanks
- All fuel tanks are connected by vent lines to vent surge tanks.
- Vent surge tanks are open to the atmosphere.
Ram Air
- Ram air is used in flight to reduce fuel vaporization at high altitudes.
- Ram air creates a small positive air pressure on the fuel surface within the tank.
