What are the risks when fueling on the airport?
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.
Personnel engaged in refuelling shall not carry lighters or other means of ignition, and shall not wear footwear with exposed iron or steel studs. Ground power units must be positioned at least 6 metres from the aircraft fuel coupling and venting points, hydrant valves and other refuelling equipment.
The main threat during refuelling operation is the fire threat. The general safety precautions for refuelling/defuelling are available in: the A220 AMP SERVICING – REPLENISHING AND DEPLETING - FUEL REPLENISHING AND DEPLETING.
- Get your plane close enough to the pumps (carefully). ...
- Make sure magnetos and master switch are off. ...
- Ground the plane. ...
- If needed, get out the ladder. ...
- Pay with your credit card. ...
- Pull out the hose. ...
- Remove the gas cap (and don't set it down).
3m radius Fuel Safety Zone, during fueling operations: – This zone extends from aircraft fuel tank vents and refuel adaptor points. – No ignition sources are allowed in this zone. – This zone extends down to the ground during fueling operations. – Driving restrictions apply during fueling operations.
Aerial refueling, also known as air-to-air refueling, in-flight refueling, and tanking, is the process of transferring aviation fuel between two aircraft mid-flight. The aircraft loading the fuel is known as the “tanker,” with the recipient being the “receiver.”
5. All fueling operations must be conducted outside of hangars or enclosed buildings. 6. After the fueling vehicle is in position, fire extinguishers must be readily available in accordance with NFPA standards.
There are two types of refueling systems, and they are the probe-and-drogue and the flying boom. There is also a combination of the two available as well. The main two are described below: The probe-and-drogue is an easier method to adapt to existing aircraft.
We ground an aircraft during the refueling process to ensure that the plane and the refueling apparatus are at the same electrical potential and to dissipate the electrical charge that is generated by the fuel transfer process.
Off course the most commonly recognized hazard is the jet fuel itself which is a flammable liquid and will ignite if the temperature of the fuel is such that vapour is created. (The temperature at which the vapours of a flammable liquid can ignite is known as the "flash point".)
What is the importance of conducting a fuel contamination check before flight?
Contaminated fuel can cause significant damage to the aircraft and engine. Damage can range from fuel system corrosion, clogging of fuel filtration components, failure of aircraft fuel system instrumentation, and even stopping the fuel supply to the engines during flight.
Large aircraft use a system known as "single point fueling," which means both tanks are filled using a single port. This refueling point is located under the right wing of plane. There are many reasons for why the port is below the wing, which we'll explore further.
What flight safety-related advantage does a pressure fueling system provide? Reduces the chances for fuel contamination. What is used in many aircraft to prevent bubbles in the fuel after it leaves the tank when atmospheric pressure is lower than fuel vapor pressure? Boost pumps.
