There are several types of aviation fuels, but the flash point is below minus 40 degrees Celsius if aviation gasoline, and above plus 38 degrees Celsius for JET A-1. In the case of aviation gasoline, it seems that there is not much meaning because it is less than 0 ° C, it does not appear in the property table. Although the ignition point of aviation fuel seems to have been tried in past various ways, it seems that sufficient reproducibility is not obtained and it is not included in the fuel standard. Therefore, although it is only an example, there are records of AVG about 450 ° C and JET about 250 ° C. It is strange that aviation gasoline has higher ignition point than kerosene type JET, but it seems to be because the number of carbon atoms is larger than that of JET.
