Funny - what's that? Alco-Test for helicopter pilots?


saw this - he moved up and down the runway at EDMO more than 10 times …


Could be one of a number of things.
Fast taxi
wheel testing(if the helo has wheels)
Air transit
Practice engine failure on takeoff
Max power (sim high alt) takeoff - Sliding the skids along the runway is interesting
sim high alt landing (landing on the skids are a fairly decent speed) - again interesting.


your guessing about wheels is right - and obviously it’s not a too small heli:

found it interesting too. this is a very small airport just some miles away but they do there quite interesting things since very long time:
