Throttle Mixture Tutorial

Postby tcco94 » Mon Aug 04, 2008 12:31 am

Im thinking about buying the Saitek Pro Flight System but before I do is there a tutorial youtube, website or anywhere where I can get a tutorial on how to use the mixtures and such.

Thanks ;)

As soon as I get caught up on some model projects.. I'm going to add some lessons re: complex (gear/flaps/constant-speed prop) planes.. and  instrument flight training...

Start using the mixture when at around 2000 feet or above in FS.

Lean (pull the mixture back) until the EGT (Exhaust Gas Temperature) peaks, then push it forward a little notch.

All depends on the aeroplane being used. :)

Where do I find the EGT?

There'll be a gauge, near the tachometer (RPM) and the like, that reads EGT.

On some planes, it'll be a combined gauge with two needles, one showing EGT, and another something else.

Manifold pressure. :) Ignore that, see below... ;D

I'll quote you on this one:

"All depends on the aeroplane being used."

I've seen oil temp more often....

NVM though :P

You're quite right. Oil temp/EGT are combined most often; I was thinking of a split MP/Fuel flow gauge.

But then again I haven't flown a piston aircraft for 18 months! ;D

A fair general rule of thumb, which works on any piston airplane with a tachometer, is to "lean for best power". In other words, back off the mixture until you see a slight increase in power, then stop when you see  the power level off.

That's the method I usually use in RL, as I don't always get a plane with an EGT. Seems to work OK.

Some engines may not really like that method, so if there is an EGT, it's best to use that (I guess), or in the absence of an EGT, use the tach but keep an eye on the engine temps (oil temp, cylinder head temp if available).

I rarely get single engine piston aircraft to an altitude where precise leaning is all that critical, as far as power goes. I'm alway shooting for that sweet-spot where fuel-econmomy meets not fouling a plug

Well my Grandpa is getting his yoke, throttle, and rudder pedals shipped to him right now. I wont have mine till Christmas but he said he would let me borrow them for a month so ill have them all October I might have to wait on a tutorial becuase im so off  ;D.
