When you instruct an EFATO and that occurs above 500ft... *
That old chestnut. Been done to death here and everywhere else. You could argue that if you're above 500' AGL, you've already turned crosswind so it's not strictly EFATO (unless you're going to argue that the t/o isn't complete until you've levelled off in the cruise). In any event, low-time pilots, students or new PPLs will survive much better going for 30 deg rather than attempt anything more extreme. (In my view)
when you insctruct for engine failure, you (a)follow the traffic pattern(b)you dont teach sideslip
don't understand the first part of the question. If it's PFLs, then these are usually taught away from the airfield to give field choice a prominent part of the lesson. We do a few in the overhead once the basics of field choice and circuit planning are mastered, in which case, yes OF COURSE you follow the circuit pattern!
Sideslip. You're only going to be doing this if you've already deployed flap. Our Cessna is placarded 'no slips with flap' so that's a no-no. PA28, sure, good technique.
when you land on short final as a normal weather conditions
you use maximum 20º of flap in a cessna 152
you use full flap
none of above
don't understand the question. May be something's lost in the translation???
Anyhow, normal landings in my book should be 'full flap', except where 40 deg is available, then only use 30.
