FOKJOK – When flying in the bush, flying issues arise everyday. You do become complacent with your aircraft and locations.
At one point a company pilot advised me to use 20oflap (Normally 10o) for a very short takeoff runs. As there was no P-chart to cover this type of maneuver, I would have been on my own if I had an accident.
My point is, unless your have received proper training or at least know your stuff. I wouldn’t be advising any young pilot to do something not covered by the manufacture or Flight Manual.
An old employer once told me that a P-chart in my aircraft’s flight manual was wrong, I bet if something went wrong he wouldn’t be backing me up. What do you think?
P-charts have been put there for many good reasons, don’t start adding your own just because I sounds like a good idea.
Yes I do have a touching faith in the manufacturer; this level of disciple was explained to me early in my training.
Back to the original question, (In a small single engine aircraft (cessna 150/172 etc etc) and so on.
I have never seen a C150/172 use much more than 10o flap. I wouldn’t touch it at all, just concentrate on stopping.
Normal rotation would be between 45 to 60 kts give or take a few knots, it’s been some time since I have flown one. At this low airspeed it shouldn’t take much to bring the aircraft to a stop.
