PilotEdge has an exhaustive supply of YouTube videos on EVERYTHING. PilotEdge is an application / service that provides an ATC system and works with X-Plane and the MS sims. They employ real air traffic controllers and their coverage includes US airports in every airspace category. They have “ratings” for every VFR level and for every IFR level, suitable for GA planes all the way up to airliners.
The service is expensive (over $300 per year), so it is intended for real pilots to learn and practice or for serious sim pilots who wants the aviation experience to be “as real as it gets”.
BUT, the training videos, workshops, and demo rating flights are free to all. Go to their web site for more info.
