Probably one rational behind keeping engine warm is that if you go to
idle and glide a long time the engine will cool down. You then slap on
full power and the cylinders are hit with a high temperature all of a
sudden.

By keeping 1500 rpm and putting down partial flaps you simulate
aircraft performance with engine out for practice (and MAY reduce your
possibility of engine problems???)

However from posts on NG you see a number who just pull back to idle
to sim engine out practice with no problems.

Of course idle engine will not duplicate aircraft performance with
dead engine. 1500 rpm and the appropriate amount of flaps will give
you very close to actual performance if you lose the engine so you are
practicing like you will fly (a good thing) with dead engine.

I'm assuming you shoot for the middle of the field (landing area)
until you see you have it made and then slip off the excess altitude?

An ADVANCED method to lose the excess altitude is to slow the bird
down (behind the power curve) and pick up a high sink rate leaving
enough altitude to dump the nose to pick airspeed back up so you can
flare? Don't try this unless you know what you are doing.

So, youse kind of pays ur money and takes ur chances )

In small high wing planes (Ie 172, 152, 150) do you do/teach pulling
throttle all the back to idel? I've been told bring it to 1500 RPM, 1
notch of flaps. Not as hard on the engine
