Checking if cargo is empty?

[Guest]

I have a chopper which inserts some units via fast rope. I want the chopper to fly away once all units are on the ground. For that, I want to check if cargo is empty but I can't seem to find a command to do it. Can anyone help?

Cheers, Ace.

Never mind, using a different method. Check if group is in chopper and then domove chopper to marker position.
