The best volume for the music would be no volume. I can't understand why anyone would add music to a lecture. Rhetorical question: When you go to school/university, does the instructor have music playing during the lecture? And for those that do need to have music playing during a lecture, well, they can easily put on their own music, of their choosing, at home.
Grant, thanks a lot. I really appreciate what you are doing, the way you explain everything seems nice and easy which really helps to deal with that continuous overwhelming stress before exams. Keep to up!!!!
I've watched 20 of these videos, and no one has mentioned that the blade you are drawing at 2:57 is cut in half and I'm looking at it from a side view. I could be the odd one out on not seeing it correctly, but everything makes sense now. I now notice the nose cone as well. Wow, I'm not sure why I didn't realize this.
Thanks for the excellent video! I have a small remark though, I think you made a small mistake on 6:39. You meant to say higher tangential velocity instead of RPM. RPM, which is an angular velocity, is always constant throughout the whole propeller blade, compared to the tangential velocity which varies depending on where you are on the blade just like you said.
amazing video bro, just subscribed so that i do not miss any more of these. Got some officials coming up and this was by far the best explanation I have had. Are you planning on doing any videos for flight planning? By the way, I liked the music in the background!
Am i mistaken in stating that the tip does not actually have a higher RPM as the root. But a higher (absolute) velocity (as opposed to angular velocity).
@@atplclass Yeah thanks :) I just asked to verify i understood you correctly because you seemed to have misspoken on 6:32. (Compliments on your presentation BTW, lovely stuff. 1st time viewer, new PPL student, i'll be watching you ;) )
I don’t get why the relative wind comes from behind the propeller, and not right in front of the plane of rotation, like a normal wing Thanks for the videos !
It's not coming from behind the propeller. We have twisted the propeller blades so that the angle of attack is now negative rather than positive which creates a force the other way. So instead of normal thrust we get reverse thrust.
Got zero takeaway for my ppl for this, not to mention the torture background music. Seems like youtube is full of people who can talk nonsense for hours and make videos to lock folks for hours
@@atplclass hope you will find the inner strength to keep up the good work in spite of these people like him. these are amazing vids thanks for everything..
@@atplclass My dear, I thank you so much fo the ATP video, so you doing a great job, please forgive this guy his strange behaviour. If he keeps flying I belive he once come back to your videos and appreciate it very much as we do! Thank you again!=)
The music in the back ground is so distracting, try to lower it little bit more, beautiful and easy to understand video thank you, i needed it
I have done so in recent videos.

Great video! I've always confused prop theory and get the questions wrong frequently (for POF). This has clarified things considerably! Thank you

Great to hear!
Loved the explanations. And change of AOA based on speed and rpm make sense now with the diagrams, thanks. (Nice tube too!)

Because everyone copies whatever written in the book,only few try to understand.
WOW... CLEAR AND STRAIGHTFORWARD
Awesome video, well explained, loved it. Just a request, do not put background music .❤
I know about the music more recent videos have the music removed
It helps me a lot with great explainations, Thanks!
Great work 👍.
Great video and explaination has helped me lot! thank you! :-)
Looking forward to more videos!!!
2:30 at positive AoA the greatest thrust is produced at 75% of the tip radius, that's why this is the reference point

You're right!
It’s Amazing , Thanks a million
Content is amazing but the music is distracting

Flight planning is probably going to be after performance and radio navigation. I will put a poll up and see which is the most requested though!

yeah the rpm would remain the same but the velocity is higher as it is travelling through more air each time it goes round the propeller hub
@@atplclass Yeah thanks :) I just asked to verify i understood you correctly because you seemed to have misspoken on 6:32.

great video thank you
Thank you a lot! so clear explanation :)
You are welcome!
This saved me for PPL GATK 😂

please do met videos
working on them just now
Please remove the background music

I hope you come back when you're ready for the ATPL's then mate. This is meant for people who want to become professional pilots.
