Yes, I get frustrated here . My gripe list:
[gripe mode on]
Students just want to do loops and rolls. Never practice turns and approaches. Yes "flying in the pattern" is boring, but you need to get smooth with the controls.

Those stupid trainer buttons, My thumb falls asleep. A switch is better even as you can keep your thumbs on the sticks. Real annoying when student takes off toward the pits and you have to find the left stick.

Test flying. I have crashed too many planes. These guys slap something together. Ignore my doubts and still expect me to fly it.

Last weekend I had a student that needed verly little input. He has spent MUCH time on a simulator. His second flight he landed.

If I get a decent laptop, I'll set up a simulator and bring it to the field.

Our club has 3 instructors. Some others will help. If one wants to fly, another will help a student. Maybe you need to get more pilots to volunteer. We can "offload" students to 5 different instructors as needed.

It takes training to be a good instructor. A buddy an I worked out what was "good practice" and a general lesson plan. But once a student learns the basics and just needs someone to "backup." Most decent pilots could do.

Then again there are a few that I would NOT want for them to help.

Burnout is a problem. There is a new club in Stone Mountain. I'm one of the few that will work as an instructor. Whenever I show up I can guarantee someone will want help.

Yes, do just say no. In our club instruction is "as available" unless you reserve a specifc time.

Maybe you should try to get more instructors. Bring it up at the next meeting.

I'm considering and "Instructor training" program to get "2nd-level" instructors that can help if we are busy or out of town.

I know the frustration. A student called me and said they wanted help. I said I would be out of town this weekend. They showed up at the field and some "unknown" instructor crashed his plane. I asked all the instructors and noone knew what happened. They were there, but apparently they left before the student arrived.
