yr right
I’ll list a few of the (many) mistakes I’ve made and some of the (many) misconceptions under which I’ve laboured, during the 30 or so years I’ve been trusting my life to piston engines in aircraft that I operate (at least to the extent that I can remember them).
1. The leaner the mixture the hotter the engine.
2. Lead lubricates valves.
3. The vibration from an engine during the leaning process is ‘lean misfire’ due to very hot exhaust gas temperatures.
4. Setting 2500 RPM / 25 inches manifold pressure in the climb will make the engine cooler than 2700 RPM and wide open throttle (e.g. 28 inches after take off).
5. 25 degrees C rich of peak is a good place to run an engine.
6 to double digits. Innumerable imprudent operational decisions that were fortunately saved by other slices of the swiss cheese not having aligned holes. I think they call this one: Being human.
I’d be interested to know some of the mistakes you’ve made and the misconceptions under which you’ve discovered you were labouring, over your 34 years’ experience as a LAME.
What were the circumstances in which you took a step back and thought: “Hang on sec’, I have this all wrong.”
