The other day at altitude in a lear the outside temp was in the minus 70's.Yes we have fuel heaters to avoid fuel system ice,however am wondering in the tanks is there a temp jet fuel (with no additive)tends toward freezing ?
Also how long does it take all the pressurized air to be completly replaced at altitude in a lear 31 or 35 or comprable corporate jet.
