      The next thing is to see if you can play a tune with the blue knob and blades.
      Like the clip of formula 1 engine doing it with flybywire throttle hooked up to a PC.
      More lag to deal with on a prop so you might be limited to playing a slow Air or similar (scuse the pun)

    Before ETPs (Electronic Tuning and Pitch), we used to have to verify pitch using a set of tuning forks. Hold the fork for your desired pitch up to your ear, then pull the knob until the prop pitch matches the tuning fork. I liked flying a little sharp of pitch, but there are those that prefer flat of pitch.

      oh damn a tuning fork is genius. On this side of the word we used saxophones for pitching the prop. The annual A&P tuning of the sax alone was a pain in the ass.

    The video of the prop changing pitch was legitimately cool. The little winglets on your prop make it much easier to see what it's doing. You might consider releasing a clip of just that with a voiceover for educational purposes. Also the bit about the "left end of the bell curve or the FAA".....bravo

      That's actually what prompted the video. I have a goPro that will do 240 FPS and I wondered if I could slow it down enough to catch the rotation. I am going to need a much faster camera to get a clean shot of it. I am looking at high speed cameras and if I can justify the expense, I will try to get cleaner footage of it and upload it stand alone.

    I don't think you mentioned, so I will. Many two engine propeller aircraft have a propeller synchronization doohickey that will detect if one engine is out of key and help the pilot tune the pitch to maximize passenger comfort.

  • @johnopalko5223

    The pitches you have available depend on the temperament of the prop. Equal temperament flies differently than well temperament which flies differently than, say, quarter-comma meantone. This is why, when you're getting your complex airplane endorsement, you should make sure your CFI is well grounded in music theory.

    I understand that you should use the key of B for Bravo airspace, C for Charlie, etc. but I'm still unfamiliar on when to use a major vs a minor scale. Are majors for departures and minors for landings or is it the other way round? What about if you are just staying in the pattern and doing touch-and-goes? Help me Bryan with a Y!

    You are scary, BrYan, but funny. Thanks for the disclaimer, especially the FAA part of it, I was dying when you said that. I DO appreciate the slo-mo on the angle of the blade for climb versus cruise. This has never made sense to me, in that in climb you seem to have a lower angle, versus in cruise when you have a larger angle, but slower speed. But, that's okay, I just trust those people who are talking about it that they know what they're talking about and would never pet the spinner or stand 18" in front of the prop. :D

Question from someone with no professional aviation experience, what is the difference between the variable pitch you showed here and the constant speed props that are actuated be weights and centrifugal force? I always assumed those were "constant speed" and the one you showed was "Variable Pitch" with the old school props beinf "Fixed Pitch".
