How to activate trigger

[eisa01]

I need a trigger to activate when any unit enters a chopper.
And if possible a trigger to activate when a chopper lands on a LSD ship.

trigger when someone entered vehicle named heli:
condition : (count crew heli)>1
if heli is empty type 0 instead of 1
if there are pilot and gunner in heli type 2
