What irritates you the most when dealing with PPL holders?
What of CPL holders?
What of FI holders?
What of Examiners?
Students?
Nothing, much.
Maybe the occasional tendency to make long winded transmissions, especially on first contact.
Anyone can do this, sometimes.
Regarding students/low time pilots, we all had to learn sometime.
What's the point in getting irritated? 'S all part of the job.
