I was petrified of my solo cross country. I can't even drive, so the thought of taking this plane 250 miles and landing twice was very, very worrying.
To make matters (a lot) worse, when I phoned the airport I was due to stop at first, they told me they were closed because an aircraft had just crashed there. You can imagine how I felt...
Still, my instructor knew I could do it, so we waited for the runway to re-open and I went for it. To be honest if it had been left to me I probably wouldn't have done it. But I did, and soon after take-off, after being switched from Prestwick to a friendly Glasgow controller, and permitted the route I wanted etc, I realised that I can do this!
Send him, don't take any crap. YOU know he can do it, and YOU are the instructor. My instructor who is normally a passive laid back guy just made me go for it. And although I was cursing him, I thanked him in the end!
I had about 6 hours solo, and a total of around 35 hours.
Pack him off with a bottle of water and a couple of chocolate bars (because it is a long way!) and as long as you think he'll be fine, he will. Make him.
Now before anyone starts! I know everyone is different, but I'm just saying what worked for me.
Happy flying.
