IGNITION PREVENTION - DESCRIPTION AND OPERATION

** ON A/C NOT FOR ALL

1. General
The fuel system for this aircraft includes design properties that prevent ignition of fuel in the fuel tank. These design properties prevent:

sparks caused by lightning strike, electrical faults or by mechanical friction.
increases in fuel temperature from heat sources adjacent to the fuel tank.
increases in fuel vapour density caused by leaks.
fuel leakage on hot surfaces.

This section includes a group of procedures that make sure the condition of these design properties stays at their best:
