Hi Fireflybob,
How did your student feel about the flight when you de-briefed him ?
Also, I'm wondering about his motives for the IMC ? When I started my IMC training earlier this year one of my main reasons was to raise the standard of my flying. I had never flown a plane with a fuel pump before, for example, nor used an ADF, VOR, etc etc. In fact, the weakest part of my piloting skills was lousy radio technique. The IMC has helped with all that.
So I'm wondering, is your student anxious to get flying, solo, in rubbish weather, in 15 hours time - or is he perhaps embarking on a longer term relationship with his club, to be nurtured into a competant and careful pilot from his possibly rather poor current level ?
In the former case, to answer your question of where to start?, then imho, start with some honest straight talking about where you think he is right now, and how you can help. In the latter, well again imho, I think you both already have made a start.
Regards, GT.
