Trigger height activation

[sgtGunneryHighway]

How can i do to prevent the activation of a trigger until the unit was geting out of a chopper for example?

you can check if your not in chopper like this

!(player in choppername)

or like this

vehicle player == player

or you could check if the chopper is below a certain height

getpos choppername select 2 <= 5
