- ATPL Principles of Flight - Class 18: Propellers.
---------------------------------------------------------------------------------------------------------------------------
Welcome to Class 18 in the ATPL Principles of Flight series.
A spinning propeller is used to generate thrust and drive us through the air. They share a lot of the same concepts as regular wings with a few key differences. Although not too hard to understand there can be a few tricky questions in the exams regarding propellers so it is worth giving them a bit of study so you don't get caught out.

Aiming to assist with ATPL theory exams and the ground school aspect of ATPL training. Including helpful tips for studying and to use in the exam.
LIKE and SUB so you don't miss future videos.
Great video! I've always confused prop theory and get the questions wrong frequently (for POF). This has clarified things considerably! Thank you
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.
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.
Loved the explanations. And change of AOA based on speed and rpm make sense now with the diagrams, thanks. (Nice tube too!)
WOW... CLEAR AND STRAIGHTFORWARD
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!!!!
Great to hear!
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
Great video and explaination has helped me lot! thank you! :-)
Looking forward to more videos!!!
It helps me a lot with great explainations, Thanks!
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.
It’s Amazing , Thanks a million
Great work 👍.
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!
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!
great video thank you
2:30 at positive AoA the greatest thrust is produced at 75% of the tip radius, that's why this is the reference point
Thank you a lot! so clear explanation :)
You are welcome!
This saved me for PPL GATK 😂
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.
You're right!
Content is amazing but the music is distracting
please do met videos
working on them just now
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.
Why but why that background music! I was searching for all tabs and all my windows minimized area to see source of the audio. Please remove the background noise.
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
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.
@@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!=)
