Never had it at cruise, but at SNA I'll experience a sudden 50 degree bank angle on final about once a month. Luckily for me I know how to handle it if the wake finds me. My muscles act on their own.
First I slow down . Chances are by the time the conflict is gone they'll call my base at a reasonable time.
If it's apparent that I'll have to extend with distance as well I'll request a 360. If they reply "unable 360" I start a gradual climb. I think to myself "When I'm that much farther I'm...
Well, usually at 1,000 AGL we are either at a recent application of full power or significantly less power, depending if we are departing or approaching. If something were wrong with the engine I'd imagine it would most likely show up at either of those times rather than normal cruise.
But...
Sigh.
If I'm in the pattern I want to make the runway. If I'm not in the pattern I'll look elsewhere. Yes there are plenty of good spots around. El Toro, golf courses, blimp hangars, empty-ish toll roads etc. Stop suggesting that I'm looking at the runway with tunnel vision and never consider...
Agree to disagree. If I get an extension I'm either slowing to MCA or climbing. For me it's acceptable risk management especially at a class C airport. All I see below me is urban area and I'd rather not put it down there. Engine failures may not be common but so what? It happened a few days ago...
Plus in a low wing getting that angle of bank steeper (say 30 degrees or so) gives you a better view of what's underneath and ahead. Just keep that ball in the middle and a spin is impossible.
So then why did you inform me that my engine could quit somewhere besides an airport and ask me "then what?" as if I'd spring for a runway 8 miles away while at 3,000 AGL in the practice area?
