Thanks for that ST. Just to clarify, I have no problem if it goes quiet - the only way is down. The problem would be if it goes a bit (or a lot) lumpy. Taking the original post as an example, if I am climbing away but speed is decaying, climb rate is reducing or reversing slightly and the engine is still running, perhaps roughly, what would I do? I'd like to think that I would do what I was taught - pick the landing spot and trim etc to go down towards it before dealing with the problem. However, and from my experience, if I can keep the aircraft roughly level and above the stall, that becomes more of a difficult decision to make and I think that there is a natural temptation to keep going as long as you can. One to practice in your head perhaps and have some sort of QR flow chart in there to fall back on?
