Several issues there but to focus on one. It seems like there is a slightly confusing situation with the airspace classes around YMAV depending on whether the tower is open or not. The details are in the ERSA and the Terminal chart directs one to the ERSA for the info.
Now this may be a stupid question but do any airlines carry ERSA on the flight deck?
If not, where does one find this information as I don't see it on the Jepp plates (though I don't have the Terminal chart).
I'm not suggesting at all that this is any excuse for the situation, just curious how you would know what class of airspace you are in at 2500' without ERSA?
