The EPA identified avgas as one of the most “significant sources of lead”. Validating the specifications, value and safety of your raw materials, products and assets. Despite atsm in the media that leaded avgas will be eliminated in the USA by at the latest date, the EPA confirmed in July that there is no phase-out date and that setting one would be an FAA responsibility as the EPA has no authority over avgas. Retrieved 3 May However, prices are so high that there have been efforts to convert to diesel fuel which is common, inexpensive, and has advantages for aviation use.

No other units of measurement are included in this standard. Vapour Pressure, kPa Views Read Edit View history.
This fuel is made by blending existing refinery products and produces detonation margins comparable to LL. The United States Environmental Protection Agency EPA has noted that exposure to even very low levels of lead contamination has been conclusively linked to loss of 9d10 in children’s brain function tests, thus providing a high degree of motivation to eliminate lead and its compounds from the environment.

The production economics of this new fuel have not been confirmed but it is anticipated that it will cost at least as much as LL. This is the main xstm why both the specific engine model as well as the aircraft in which it is installed must be supplementally certified for the conversion.
