Aircraft Fuel Storage and Refilling or Recharging System

Fuel Storage System

Each fuel tank must be able to withstand, without failure, the loads the loads under likely operating conditions. Each tank must be isolated from personnel personnel compartments and protected from hazards due to unintended temperature influences. The fuel storage system must provide fuel for at least one-half hour of operation at maximum continuous power or thrust and be capable of jettisoning fuel safely if required for landing. [Figure 1] Fuel jettisoning systems are also referred to as fuel dump systems. [Figure 2]

Aircraft fuel tanks must be designed to prevent significant loss of stored fuel from any vent system due to fuel transfer between fuel storage or supply systems, or under likely operating conditions.

Fuel Storage Refilling or Recharging System

Each fuel storage refilling or recharging system must be designed to prevent improper refilling or recharging; prevent contamination of the fuel stored during likely operating conditions; and prevent the occurrence of any hazard to the airplane or to persons during refilling or recharging.
