The main problem is to do it a "safe way". For a multirotor you can use amp-draw, but not all use current-sensor. For plane speed would be a fine trigger.
All in all, it's possible, but a bit difficult to make a good solution to all platforms. Especially due to the fact that the GPS is quite inaccurate in the beginning.
