I am a aviation student. I haven't been able to fly in a while because Arizona is windy a lot. However, the last two days him and I were briefing on VORS and he didn't tell me if we were going to fly today and I felt bad to cancel last minute because I wasn't feeling well because I'm not used to this extreme warm weather I felt dehydrated if I was briefing only I would have stayed. I am wondering if any of you think that he has the misconception that I am not taking my flying seriously.
