What are the different systems found in aircraft?
This chapter covers the primary systems found on most aircraft. These include the engine, propeller, induction, ignition, as well as the fuel, lubrication, cooling, electrical, landing gear, and environmental control systems.
What are the primary hazards and potential errors associated with Refuelling an aircraft?
The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. A sufficient quantity of fuel vapour to create a high risk of ignition may result from spillage arising from procedural errors, leaks, aircraft tank venting or failure of pressurized fuel lines or their couplings.
What aircraft systems should not be operated during refueling?
It is absolutely necessary to prevent a source of ignition anywhere near the aircraft during fueling or refueling. Any open flame, such as a lit cigarette, must be extinguished. Operation of any electrical devices must be avoided. Radio and radar use is prohibited.
What is the safety precautions during refueling?
check the correct grade of fuel is used. Also, ensure there is a proper bonding and groundings between aircraft and tanker, aircraft and ground, tanker and ground, and nozzle and filler port. Do not smoke and no use of naked flame or equipment that can cause spark and ignite fuel.
How many systems are there in aircraft?
All aircraft have a requirement for essential systems such as the engine, propeller, induction, ignition systems as well as the fuel, lubrication, cooling, electrical, landing gear, and environmental control systems to support flight.
What is the disadvantage of using aromatic aviation fuel?
What is one disadvantage of using aromatic aviation fuels? (1) If avgas vaporizes too rapidly, fuel lines may become filled with vapor and cause increased fuel flow. (2) A measure of a gasoline’s tendency to vapor lock is obtained from the Reid vapor pressure test.
What are the aircraft Fuelling hazards?
Chemicals, including jet fuel, may also present toxic or irritant hazards. At high concentrations, jet fuel and other hydrocarbons can affect the nervous system, causing headache, dizziness, and lack of coordination. Chemicals may also cause chronic health problems, such as liver and kidney damage.
How can you minimize the dangers when Refuelling an aircraft?
Sparks like this can be dangerous, potentially igniting a fire. A build-up of static charge is a potential danger when refuelling aircraft or vehicles. Fuel running through the pipes can provide the friction needed to create a static charge. To prevent this, aircraft are earthed with a conductor during re-fuelling.
What precaution must be observed to reduce the possibility of fire when refueling a vehicle?
Do not allow smoking, flames, sparks or other sources of ignition near the fuel storage and handling areas. Gas vapours are heavier than air and will drift downward from the source. It is the vapour, not the liquid, which burns.
Which are the types of fuel supply systems used in jet engine aircraft?
In general aviation, there are two main aircraft fuel types, which are AVGAS and Jet Fuel.
