Which prop?
Well, if you have no oil pressure you won't be able to change a CS prop. If the engine is free wheeling in the wind you should have some oil pressure, pull the blue knob for course pitch. If your engine is seized don't bother pulling the blue knob. Fine pitch had more drag.
Educate me. I know my CS will go to fine pitch with loss of oil pressure. I'm not sure about the drag penalty of a fine pitch prop being worse IF the choices are:
a windmilling prop in coarse pitch or a stopped prop in fine pitch.
So my side-question is will the prop stop if the engine has lost oil pressure and the prop goes as flat as it can, or will it keep turning - because if so the coarse pitch is clearly the better option, but if not the fine pitch may well be less drag.
I know a seized engine won't windmill but I am speculating about situations where pressure is very low but not zero. Are there any such, that could last more than a few seconds?
However, it does take a bit to get the prop to stop wind milling and that is the time that is spent during an emergency. It does take some practice, at least for me, to do that with the calm head. I have shut down my engine, even though high and above an airport, the rush and nervousness is still there.
If the engine fails down low and theres no time to jack with it, then yes just pull the blue knob back and fly the airplane into the crash. If you're up higher at a decent cruise altitude, then you have time to pull up and stop rotation, to improve sink rate and pick a landing site.
WOW... Great job flying the plane to the ground. Beautiful Falco. Beautiful country to fly over. Glad you are OK.had an engine out experience a few years ago on a Falco equipped with a Lyco O-320 coupled to a Hartzell prop, Still thanking my guardian angels
Pretty deep for RV forum and a slight thread drift, but 1%, my estimate is that is correct divide that by infinity (indeterminate). The theoretical physicist say a lot of things, because it is "SCIENCE!" Scientist are humans and have ego at play. I'm of the mind that what we do know about creation of earth, life on it and all that surrounds from solid scientific standpoint (Observable Phenomenon, Mathematics, Data supported by repeatable experiments) is infinitesimal. We may never know, except for theories, which is fine as long as those theories are not "believed" on faith only. Big fan of general and specific theories, but to your point we know little about the universe.Zürich W, Switzerland, Europe, Earth, Milky Way, known Universe... well said. it is estimated that the known universe is only 1%, the rest is unknown. some hypothesize the the big bang is a recurring cycle and we could be on the billionth big bang cycle. knowing this, we should all be flying more. should I prime or not prime, that is the question.
