P1/s
Yes there is alot of that about.
For club checkouts, there is no reason why they cannot log it P1 as long as you (FI) do not touch the controls.
I made the P1S mistake when I started instructing (check-outs). AS someone above stated, Its just for auth. examiner stuff.
LASORS can be a bit confusing sometimes. Whenever I had a question about licence stuff and got a headache trying to readtheabove document, I called the CAA. Generally really helpful and if theyculdnot give you an answer staright away, I got an e-mail.
