Hi there,
First post so please dont shoot me down for what is a stupid question!
So my shiny new PPL license arrived (finally) this week and tomorrow i am going on my first flight as a PPL holder!
Whilst i have been waiting for my license i have been filling my time thinking about what i am now going to do with it and how i can slowly improve my flying technique.
Something that didnt come up much in training was leaning the engine. When i did ask my instructor he was very unsure of the proper process and kinda bumbled through it - and then said but i fly fully rich all the time and as such he wasnt 100% sure!
So i then looked at the POH which gives a clear explanation (which incidentally is different to what the instructor showed me!). The POH says that leaning should be done below 75% power. So here is the silly question.....
What is 75% power??? I was taught to fly a lot of things by engine RPM..... so would 75% power be 75% of maximum revs? If so 75% seems to be a lot less than the RPM i was also told for cruise (i was taught 2300 - 2400 for cruise). Or is 75% power something else that i am missing.
See told you it was a stupid question!!
You will be please to know i dont intend playing with this on my first PPL flight - i am going to keep it simple..... but this has been bugging for a while so thought i would sign up to flyer and ask the question!
Oh and one last totally unrelated point - thank you to the people on here who have also done the blogs (and Leia Airborne in particular). I read through the them before and during in training. Before hand a lot of it bamboozled me but it was nice reading about the exciting times that were coming up! During training I could totally relate to what was written…. Including the days after a bad flight where you have messed up, you feel really down about the flight and then you remember you now have to hand over a small fortune for the privilege of feeling so down about it!!!! It was nice to know I was not the only one with those feelings!!
