2015年1月30日 · 87UL/E0 (similar fuels are called 82UL or 85UL) -- This is a tightly specified form of motor gasoline (mogas) -- without any ethanol or oxygenates in it, as many aircraft fuel systems aren't compatible with ethanol -- that is used in low-compression aviation piston engines mounted in airframes certified or STCed for operation on motor gasoline ...
How much water should there be in Jet fuel for it to be considered …
2024年11月13日 · The Current Regulatory Provisions on Aviation Fuel Safety: There are no SARPs yet on the aviation fuel. Following an accident met by A330 aircraft of Cathay Pacific Airlines in Hong Kong in 2010, the International Air Transport Association (IATA) had developed a manual on Civil Aviation Jet Fuel Supply which was later on circulated by ICAO as ...
What is the measurement system used in the aviation industry?
Pounds for the fuel quantity on the aircraft (read by the fuel gauges) Pounds/hour for fuel flow; Gallons to order/purchase fuel; These are pretty standard in most of the Americas (North/Central/South), but in certain parts of the world some of the units are different: Meters for height; Kilometers or meters for distance and weather
refueling - How do you know which fuel an aircraft uses?
2017年7月11日 · They can also often burn aviation gasoline or avgas/jet mixes but under operating restrictions that will be mentioned in the AFM. Large turbine engines will require jet fuel, and kerosene-based jet fuel at that -- they cannot run on wide-cut jet fuels such as Jet-B or JP-4, likely due to boiloff issues. These aircraft take enough fuel, though ...
What is the history of "Joker" and "Bingo" fuel terms?
2018年2月14日 · Aircraft is considered to be in an emergency/fuel critical situation. Bearing, distance, and destination shall be provided." CV NATOPS MANUAL. If the aircraft carrier was operating in an area that had a land based alternate airport, it would be called "Bingo Ops". "Bingo Fuel" was the amount of fuel remaining to safely reach the "Bingo Field".
fuel - What is the Difference between mogas and avgas?
2019年11月6日 · Another minor issue is leaded aviation fuel doesn't like synthetic oil. Synthetic oil's chemistry can't keep the lead is suspension so it forms "lead paint" inside the engine. This was a problem when Mobil AV1 aviation oil was introduced (there was a big class action lawsuit).
fuel - Why do jet engines use kerosene rather than gasoline?
2015年3月4日 · natural gas is commonly used as a turbine fuel in pumping stations: it's already there and thus is "free". The required pressure vessels make it impractical to use as an aircraft fuel. So kerosene basically became the standard turbine fuel because it's: cheap: kerosene makes up a rather large fraction of crude oil.
How do aircraft keep fuel from freezing while in flight?
Initial fuel temperature. If you fuel in the middle east during the middle of summer, the fuel will be a lot warmer than when you fuel in Siberia in the middle of winter. Warmer fuel will take longer to freeze. Outside air temperature. Much like trying to freeze water to form an ice cube, the colder the air around it, the faster that it will ...
What are the ICAO fuel reserve requirements? - Aviation Stack …
Additional fuel (if needed to guarantee ability to reach an alternate with an engine failure or at lower altitude due to a pressurization loss) Discretionary fuel (if the pilot in command wants it) General Aviation. For general aviation, ICAO Annex 6 …
general aviation - How is engine fuel kept from freezing?
All aviation fuels contain some (small) amount of water, which cannot be extracted. At (high) flight altitudes, the fuel cools and its capacity to retain dissolved water is reduced. Some of the dissolved water separates out as discrete water that can form into ice crystals, blocking filters or form supercooled liquid which can crystallize and ...
