I'm not positive, but I think the regs say something to the effect
that if you land with ANY JP4 on board, you have to be fully defueled.
If you have JP8, I think they'll allow a 50/50 mix with JP5 on a
refuel.

Four refuelings before an airplane that had taken JP4 on board could
be struck below to the hangar deck. Until then, it stayed on the
flight deck. No need to drain the tanks.
