What if an Assault Marine do not pass a pilot personal test to charge an enemy?

Are you talking about the special ability Wings of Angels? If you are, then I would run it under these conditions. Remember, using a jump pack means that they have to land at the end of their Turn unless they're using it at maximal thrust to gain the Fly Trait.

1) If the opponent was within range of his regular charge and the assault marine did not pass the Pilot (Personal) Test: he still charges the foe but does not gain the benefit of Wings of Angels.

2) If the opponent was beyond the range of his regular charge and the assault marine did not pass the Pilot (Personal) Test: he would logically stop short before the enemy and miss the rest of his turn since a charge is a full action.

3) If the opponent was beyond the range of his regular charge and the assault marine scores several Degrees of Failure on the Pilot (Personal) Test: GM's choice of having several...interesting things happen.

Charging an enemy with a jump-pack, in most circumstances, isn't something that would require a piloting test. Generally, if its not something that would require an agility test to do it with ones feet, its simple enough to not require a test to do with a jump pack.

Difficult maneuvers (flying through a small opening while flying through rubble from a collapsing building for instance, or landing on a 2ft. ledge) would be things that would warrant a piloting test. Simple movement, even charging, not so much.

Jump packs double a Space Marines agility bonus for movement (Ag 40 = half move of 10 using the pack, [4 +1 for hulking] X2) if you choose to move with the jump pack. (Which I think warrants increasing the packs flying speed, its fairly easy for a space marine to get more than 12 move rate with normal movement. Who needs to use the flying mode when you're faster out of it.

thanks you for the tips

You use flying mode for the same reason birds fly instead of just run fast.

Yeah, it'll let you fly, which is really neat. My point was, a space marine with agi 50+ is as fast or faster than the fly speed using jumps. It just seems the fly speed might could be a little faster since its putting out more power flying than hopping (hence the cooldown time) but you're still going slower than hopping which you can do indefinately.

Maybe its drag, or the marine is giving it a bit more speed from his jumps off the ground, I don't know, but even these are a bit week of a rationalization.
