Str8: Get it all the time on Hangliders (lots of hours) but not on Helicopters (a huge 68 hours!).
Last time it happened, a wise and 3000 hour HG pilot walked me round my rigged glider and pointed out the relative strengths of the tubes and components, he pointed out the conditions and that I had flown in such before, he asked me about my flight plan, landing options, soaring pattern and what I would do in various emergencies. He asked me to talk through what my take-off/overshoot technique would be and why.
I realised that half way through he had a look in his eye that said 'You'll be safe, you will enjoy it, you will think through any problems - you big nancy'.
And of course he was right. Talk through your next flight with someone you trust, remember to bring up those small stupid things which worry the cr*p out of use but are a breeze to the high timers, and you'll have a very enjoyable flight.
Best regards
Cron.
