Hi,
I'm learning to fly in Robin HR200's, and anyone who has flown/ flies the HR200 will know how small it is inside when you are sat next to a passenger / instructor.
Well, on one of my lessons, It was a relatively chilly day so decided to wear my jacket, and didn't thing about body heat inside a small stuffy cockpit....
During the flight I became very hot, and just couldn't seem to concentrate very well on the job in hand.
When we were returning back to the aerodrome, turning finals, I was boiling hot and just could not concentrate again..... Anyway the approach wasn't good and the landing was the worst I've ever done, I bounced.....
Although...... It was only my 3rd time landing an aircraft!
A lesson learnt - always thing about your clothing, are you going to be too hot or cold?! I'll never forget that one...
