flyboy6876 - your thread didn't work.
All, thanks for the input. Have to say that I am amazed at how many of you were seemingly taught mixture adjustment at PPL. I was definitely given the impression it was outside the syllabus.
Sultan, I have to say that you will naturally think that knowledge of using the mixture is a necessity if you learn to fly in places like Jo'burg
. I would venture it is not one when your PPL aerodrome is at 72' and there's Class A from 3000' or so.
Still it's now on the agenda, I've been reading up:
* Don't do it at 100%, wait till you've settled into 65-75% RPM
* Lean till either the tacho peaks out, or the engine roughens, then enrich till the engine's smooth.
* Relean every altitude change
* Enrich on downwind checks (so that's what the M stands for in BUMFFICHH
)
Thanks all!
