HH - thanks for that! I've actually started a thread on another forum, about this very subject. I've come to the conclusion that I'm happy enough with myself to take a passenger up now, providing my hour with a FI is alright. However, only in good weather and well within my limits. And the flight will be a local route - around the area which I trained in.
Just about flying near mountains - I'm very keen to go to the lake district at some point, but think I'll be going either under instruction or with someone more experience in those circumstances for that very reason - I wouldn't like to be solo in a situation which mazzy described!
Thanks all, hopefully my first passenger(s) will enjoy the flight! (As well as me!!)
