propellers and mixture?

[juanca]

Can you please tell me what is prop and mixter used for and when do I use it

Mixture is the ratio of fuel to air.  At higher altitudes (I usually don't mess with the mixture until about 20,000 feet) you need to add more air to compensate for the thinner air at altitude.  I add air until the performance starts to decline then back off a little.

Prop trim is like changing gears in a car.  After you get to cruising altitude you should trim the prop to get better fuel efficiency.  Watch the fuel flow gauge and trim until performance starts to decline, then back off a little.

[juanca]

then why put mixture controls on a cessna 182 (for example) if its maximum altidude is much lower than 20,000ft

[WebbPA]

I don't mess with mixture until 20,000 feet.  Proper procedure would be to start messing with it at about 5,000 feet.

Juanca if you are playing with quite high realism settings then remember the following;
Fine pitch on the prop on take-off/landing, coarse pitch for cruisin' This is for better performance without thrashing the engine to death.
The mixture has to be adjusted or you'll flood the engine with more fuel than air and it stalls, which is NOT good Also by thinning the mixture you can get greater range

I start weakening my mixture once above 2000 ft ASL.
(My real flight instructor does the same thing).
Once the trim, throttle, prop control and mixture settings are correctly set, the aircraft will fly faster and more efficiently... ...!

Cheers...!

Note: If your airfield is above 5000 ft ASL the mixture will need to be weakened for a quick, successful take-off... ...!

I'm sorry but I still dont understand this prop and mixture  issue

If I lean the prop, the rpm descend!! and if I lean the mixture rpm go up!

also when I lean the mixture so that the fuel flow gauge needle marks the green, the engines killed!

?

Can you please explain me what is the misterious rtelation b/w the throttle and mixture and prop?

and how to use them a correctly and as realistic as can.


thanks again

Pick the default Cessna 182, and practice with the throttle prop and mixture controls.

Pushing the black throttle knob in speeds the engine up.
Pulling the blue prop knob out coarsens the prop pitch.
Pulling the red mixture knob out weakens the mixture, (fully out will stop the engine).

Cheers ....!

Paul.

P.S. ..practice the "Flying Lessons" with the instructor in the simulator... ...!

[juanca]

Yes I know that! thank you for all that good information,

BUT!, What I want to know is, like I've said before, Is what is the relation b/w throttle, prop and mixture.

And most importantly, what is the proper procedure, or even better;  what configuration should I target (relationshp) with these three levers, during the three stages of flight?

Thanks

Pick the deafault Cessna 182 Skylane, (the fixed wheel version!), as shown here...>>>



Locate these gauges and remember them:

[juanca]

right on fozzer!
Just the information I needed
Thank you very much

Now.... here comes the obligated question

How do you get to see people and buses and cars and all, in that gr8t picture?????

Hi Juan...!
When you have fully mastered the controls on the Cessna 182 Skylane, can fly it to the satisfaction of your Instructor, and have obtained your Private Pilot Licence, come back again and I will let you into that little secret.... ... ... ... ...!
Tee-Hee...
LOL...!

Cheers... ...!
