Which has a higher flash point?

Jet A has a higher flash point than avgas. The flash point of a fuel is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Jet A typically has a flash point of around 100-150°F (37-65°C), making it less volatile compared to avgas, which has a lower flash point, typically ranging from 70-100°F (21-38°C).

This means that Jet A is less likely to ignite at lower temperatures than avgas, leading to a safer handling profile in aviation applications. The higher flash point of Jet A is a critical factor in aviation safety, especially in environments where fuel can be exposed to heat and ignition sources. Understanding the flash points of different aviation fuels is key in assessing their flammability and ensuring safe handling practices in aviation operations.
