The stangest thing......
Can someone answer my query?
I was flying down to Devon today in my PA2-160.
I decided to fly at 6500ft because it was smoother and the trip was going to be at least an hour and I just wanted to get away from gliders etc etc.
The air was smooth and I trimmed the a/c perfectly. So perfectly that I had flown hands off for at least 5 minutes and something possessed me (in boredom) to open the DV window.
As I did this the a/c started to climb at about 300fpm. Why? What caused this? I spent ages trying to fathom it out but couldn't explain it.
Any ideas?
