The effect on aircraft Upset or latent failures may pass quality control testing programs or static damage may occur that cannot be felt, seen, or detected through normal procedures. The reason for using a bonding strap during refueling is that when an electrically, non-conductive fluid like Jet A or 100LL is transferred, these liquids build up static electricity that can arc and cause a fire if not dissipated. An earthing strap connects the pipe to the ground (the Earth). Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. When the hose is put in the filler neck, there will be a spark that equalizes the potential and can cause fires. You may apply lotion or moisturizer on your . conducted away. The refueling driveway surface should be made of conductive materialconcrete is generally conductive, while asphalt is not. When the aircraft charge is great enough, it discharges into the surrounding air.
Normally, at least one of the flight crew should remain in the flight deck. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality.

Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. How do you get rid of static electricity in your body? There is a risk that a PED (personal electronic device) may create or induce a spark of sufficient intensity to ignite fuel vapour released during fuelling but it is extremely remote under normal circumstances. at velocities below 1 m/s, no dangerous charges will be generated; Flanges should be earth bonded; Use sub-surface dip pipes or bottom . The fuel itself is an insulator (a hydrocarbon)
Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. This is also true for people who mix some gasoline with their diesel fuel in the winter. The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. Conductors and insulators Never jam the refueling latch on the nozzle open. Static electricity is created when objects with different electrical properties come into contact, and negatively charged electrons from one substance are transferred to the other. But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize How can Fuel Flowing

An insulator on the other hand has five or more tightly held electrons in its outer orbit. Give one reason why earthing reduces the risk of fire. Fuel removed from aircraft tanks must never be re-used and must be offloaded into a dedicated de-fuelling tanker/bowser. is the same as above. Procedures for Emergency Passenger Evacuation should take account of the availability or otherwise of airbridge access and in-position ground steps in the selection of exits to be used. Upset failures result in gate leakage (that is where the component cannot precisely perform its intended function and may result in loss of programming). When the aeroplanes are charged after travelling in the air and contact with air particle the potential difference between it and the Earth is very high so electrons try to jump from the craft to. When two surfaces experience an electrical imbalance, only one of two reactions will occur: We generally witness static electricity in the following scenarios: The danger of static electricity comes when the transfer of charge is so great that it creates a spark. . This is a form of ESD. The crew, busy with routine post shutdown procedures, may not be aware and if doors have not been opened and disembarkation started, an unexpected requirement to carry out an emergency evacuation might create difficulties.
