Where did you obtain your performance figures for contaminated runways before attempting this ?
I didn,t
From the written statements at the beginning of your video it seems you were just guessing and trying various aircraft configurations without reference to the AFM
Absolutely Correct, I was just trying different things, the AFM is a guide only (usually a best case scenario for a new plane with a new engine/prop and with a hot shot factory test pilot) and can't give exact real world figures for distances due to individual aircraft of the exact same model having differences in engine and prop condition, pilot technique and many other factors. the numbers at the beginning of the vid came from my nephew pacing off the wheel marks in the snow after each TO and Landing.
To me you arsed up the take-off at the point were you attempted the whole exercise.
Perhaps, But i now know what the real landing distance are when both the plane and myself are pushed to the limits of our respective
current capabilities which for the type and location of flying i do is important to me, for example a lot of my flying is between the east to west coast of Scotland which is mostly hills and mountains with sheep farms where the upper areas are steep and impossible to land on without duffing up the plane or myself the lower areas around the farm houses are small non arable (usually grass) pastures and paddocks and rarely exceed 400 to 500 feet in length with drystone dykes at each end. I now have a better gauge of where I can and can not get into in an emergency which frames my options a little tighter and perhaps makes me a safer pilot for my passengers and myself, and that at the end of the day is the name of the game.
