Going to start working on my high performance endorsement today. This really helped de-mystify the prop control and made me feel a lot more confident going into the 182 for the first time. Thanks!

Amazing video, I have been so puzzled by this knob for sometime and been having difficulty wrapping my head around it. This video was absolutely amazing, I now have a much much better understanding. Awesome job lad👍🏼

You can think of a fixed piched propeller as a car that is stuck in Second or third gear. Second is great for circuits and climbing, but lower top speed. Third gear is sliwer to accelerate and climb, but great for cruising.

This video helps so much, yk I’m kinda glad I’m a DA40 student pilot 😂

Great video... got my endorsement last week. Feels awesome to feel like I am evolving as a pilot,

On a complex airplane, full throttle is not full power unless the prop is turning at maximum RPM. The formula for shaft horsepower is; Torque x Prop RPM x .00019=Shaft Horsepower. From the formula, it can be seen that if max RPM is not set, max power will not be achieved. Also, with the prop turning at high rpm, the blades are at a finer angle and produce more thrust.

Great video, really helped crystallize it for me.

i would like to add you can also have round pitch propellers. i am taking my FAA powerplant written exam.

Question - on the dual engine, talking about feathering - for the failed engine - do you set the propeller for a fine or coarse pitch for the reduced drag?

[rexschlagenhauf]

Thank you for the video. Just for purposes of demonstration I think that having the "camera" focused on the levers rather than the outside view of the landscape would be more beneficial. If you want to demonstrate how the levers work...show the levers and the resulting reaction by the rpm and manifold pressure. Graphics are crisp but there's a little bit of jumping around as you are preparing for takeoff. Good luck in future videos.

[MAGApepe]

nice, , , i know to keep engine pressure lower than prop speed, , , , what happens in a turbo engine when the pressure will likely always be higher than prop speed ?

[joe-nn]

When decreasing power after take off, at 1100' elevation, you reduce prop pitch RPM before manifold pressure. Isn't this the reverse of what you recommended earlier in the video?

Jesus fucking christ I finally understand this shit!!!! Thank you! Do one on supercharger gears for the love of god

Getting ready to fly the 181, 200s and 201s😩

[bitcinlightningrules]

The part i had trouble with (exam question) is that you increase the pitch when descending, this is counter intuïtieve because you want to fly slow.

[joseignaciobejar]

Amazing video, captain ! What simulator program is that ? Thank you very much

[aruhtaz]

great explanations, thanks! liked and subbed, it was a given seeing you spent 400$ an hour for that bird. Good credits.

[karimnahle]

Great video, getting ready to write my TC PPL written, this was very helpful

[yourpilotjoe]

My question becomes. When you set your prop rpm’s how do you know what to set your manifold pressure as? Like how do you know if your manifold pressure is set too low or too high in either cruise, a T/O or Landing config?

[LSC]

On your climb out shouldn’t you have reduced throttle prior to reducing RPM with pitch to avoid high cylinder pressures?
