I turn it on right after wheels up...
I too, turn the Damage List ( Ctrl D ) on right as I am taking off......
what would be better is if it could be tied to each individual aircraft's settings like your hps , gunsight, convergence, etc......
this way one could turn it on or off for each individual aircraft / GV / Boat etc ... what ever their desire might be for that particular platform they are using to play ( fly, drive etc... )
just a suggestion added to the original request
I am for it
