Sorry about all these biginner's queries.
Wheel chocks are fine, from cold (on/off, no problem)
After I have done my engine checks (26"-2000RPM) and I reduce to 1000RPM, wheels chocks won't disengage, by that I mean, I have lost the spot for the mouse click. I can't imagine it's because the plane has moved squarely against the chocks (it happens in real life, mind you...)
So no flight !
This has now happened twice, after having restarted the sim.
Has anyone experienced this before ?
EDIT: OK, since this post, I notice that releasing the handbrake will make the chocks disappear ... so !
