Desision making:
I had planned to ignore this subject of engine failure at night but decided to share my personal rules regarding flight safety considerations.
I have three rules I do not break.
( 1 ) I do not fly single engine aircraft beyond gliding distance of land.
( 2 ) I do not fly single engine aircraft in IMC nor do I fly single engine aircraft outside the aerodrome circuit at night.
( 3 ) I do not fly multi engine aircraft IMC single pilot.
Please note,, after fifty years flying many, many different aircraft fixed and rotary wing for about thirty thousand hours and having experienced just about every conceivable failure of engines and equipment both piston and turbine one could imagine I made these decisions years ago based on the math that if I keep flying in risk areas that I do not have to fly, eventually the odds would run out.
Please note:::
These rules are my own personal decision and I do not mean that others need adopt same.
Just thought I would post this for you to mull over.

The hardest thing about flying is knowing when to say no.
