A lot depends on whether the pilots are on overtime.
I have found you need to get down and dirty and just soak everything - this is obviously not recommended when it's really blazing, but if you're doing jumpspots and chicoes, it's very effective (one tip - when hover-dropping in the Astar, get the target centrally in the last inch of the floor window - 100% every time - the higher oyu get the more you need to come forward)
