Re: What is the PEL of JP5, Jet Fuel?

Dear Friend,

IĄve heard from our Operations Department that Boeing recommends JP4 fuel
for civilian airplanes.  As long as I know JP5 is a special fuel with 
better
freezing resistace and lower density changes due to high level flight (high
altitude, above 40,000 ft.).  ItĄs for military aircrafts mostly.

Anyway, I didnĄt discover does PEL means.  Sorry not being helpful this
time.

Best Regards,

Fernando Grau
