Fuel system includes

• fuel lines and pump

• fuel tank, fuel lines and fuel pump etc .

• Electrical spark, fuel pump and bonding cable

What is airworthiness limitations (AWL);

• a. All Weather Landing systems

• Any component which limits the airworthiness of the aircraft

• Directives mandated maintenance and inspection requirements to ensure unsafe conditions do not occur

AWL’s are divided into;

• Critical Design Configuration Control Limitations (CDCCL), Airworthiness Limitation Items (ALI)

  
  

• Airworthiness limitations (AWL), Critical Design Configuration Control Limitations (CDCCL)

• All Weather Landing (AWL), Critical Design Configuration Cable Limitations (CDCCL)

TWA Flight 800 crashed IN?

• 17 july 1997

• 17 july1996

• 17 june 1995

Ullage is

• Free space above the water and fuel

• Free space above the liquid contained in a barrel, drum or tank, provided to accommodate expansion of the liquid

• Free space above the fuel

In order for fire to occur which 3 elements must be present;

• combustible material, air, friction

• . oxygen, paper, heat source

• fuel, ignition, oxygen

If altitude increases

• flash point will increase, and less energy (heat) is needed to ignite the mixture

• flash point will increase, and more energy (heat) is needed to ignite the mixture

• flash point will decrease, and less energy (heat) is needed to ignite the mixture

The purpose of Critical Design Configuration Control Limitations (CDCCL) is:

• to make sure dual inspection carried out

• to upgrade aircraft critical features to modern technologies

• to provide instructions to ensure aircraft critical features are present throughout the life of the airplane

1. Sources of ignition that could cause fuel vapours in aircraft fuel tanks to ignite:

• Friction sparks or heat, hot surface ignition

• Hot surface ignition, fuel pump

• Electrical spark, bonding cable

OBIGGS

• on board inter gas generating system

• on bord inner group generator system

• on board inter gas generating ship
