Solo
I'm not an instructor and I'm sure some will be along here soon with sage advice but here's my 2p's worth.
Have you spoken to your FI,you are after all the customer and paying a lot for the privilege?
Ref the emergency procedures (remember I'm not a FI),during you circuits presumably you would have practised EFATO,glide approach and flapless which can be typical circuit 'emergencies',also how to get to the nearest alternative airfield in case someone else had a probelm when you are alone in the air.
Have you passed Air Law-not mandatory but most FTO's insist on it?
Do you have a current medical-you can train dual without one?
Hope things work out for you-I didn't solo until 21hrs and passed at 48hrs.
Do talk to your FI ( or even CFI if getting nowhere)
Good luck
MM
