Keep on watching for a quiz about the subject at the end of this video. Would you like to support this channel and help us grow? Visit flight-club.com.au to find out how.
I must have looked at dozens of videos on this very subject, but yours is the only one that explained AOA with the level of clarity, necessary for someone who knew nothing about the subject until today. You have the right insight and intuition to be a genuinely informative teacher. Thank you!
Going to university this year and going to study Aerospace Engineering, watching this video helps me get a head start. Thank you!!! I'm gonna watch all your videos.
Informative video Thank you so much It becomes hard for me to get answer of question due to red-green colour blindness Please make it different way in future video
Wing loading is relevant to AOA and relative wind because a heavily loaded aircraft will fly with more AOA and the relative wind will also change the affect of this is a high stall speed and slower flight for the same amount of power. increasing the G force is another way to increase wing load and raising the stall speed.
Could you please elaborate on Question 3? I thought the answer was the one above the correct answer, but I am unsure to why the bottom one is the more correct answer.
Certainly, this is a tricky one. The third answer would be correct if it said: "relative airflow is opposite to the direction of movement of the aircraft relative to the atmosphere", not "flight path". Thank you!
Yes, and the relative airflow is the flow of the air while it is undisturbed. Airflow around the airfoil gets disturbed in the boundary layer, thus its not relative air flow anymore. See the video on Stalling.
Not necessarily as the angle of attack depends on the relative airflow which is related to the flightpath. I explain it further in this video: czcams.com/video/jo24pruCz4U/video.html
Shouldn’t the answer to Q6 be the “curved line...”? As the mean camber line cuts the wing directly in half and requires the curve, however the chord line is straight.
Hello Pilots, Do I understand it right that, Stall will happen when you have a large angle of attack at relative low speed? But if, with the Same Angle of Attack, the speed is much higher, then stall won't happen. Right? And the plane will climb up of course. Right? If not right, Then how come that fighter jets and other acrobatic planes can climb straight vertically? I suppose this is because of their high speed, which provides enough lift, no matter in what direction or angle they move. So why can't normal plans in a critical angle of attack give full thrust to gain more lift? The air is the same everywhere in the sky. Why behaves the air different if we want to fly in an angle which is not parallel to the horizon?

Thank you!
Wow, thanks!
Great video! The fact that there was a quiz to test our knowledge, makes us pay more attention! Great!
5:23 you may ask the chord line which is a straight line
Love the quiz section. Please have more of it in each video!
Eleven people flunked the test.
Going to university this year and going to study Aerospace Engineering, watching this video helps me get a head start. Thank you!!! I'm gonna watch all your videos.
Thank you for clarification of that matter I got confused whilst reading stick and rudder
Helped me in playing Microsoft flight simulator
Awesome. Thank you!
Thanks. Studying for the ASTB
Helped me to understand what AOA is
the relative airflow is the opposite to the aircrafts movement in an unobstructed atmosphere right?
Thanks a lot for this video..particularly, for the quiz round @ the end.....😍😍😍
Most welcome 😊
what happens when we lower the flaps why does the angle of attack decreases , shouldn't it increase since the trailing edge comes lower ?
Nice video! Appreciate your effort in making this great video! Make me more clear about the concept! Keep it up!
I like the question systems.
Informative video
Thank you so much
It becomes hard for me to get answer of question due to red-green colour blindness
Please make it different way in future video
Good info
Thank you I have a science text coming up soon and I was confused on this
Thank you.. This is helping me review in my PPL
Glad it was helpful!
In this video you showed some straight lines indicating relative airflow . Were those lines (relative airflow) parallel ?
0
Shouldn't the last question be the chord line?
brief and helpful, thanks
No worries!
what's the name of musical background you use in these videos?

Happy to help

AH!!! YES! Thank you so much!
Yes, and the relative airflow is the flow of the air while it is undisturbed. Airflow around the airfoil gets disturbed in the boundary layer, thus its not relative air flow anymore. See the video on Stalling.
so what's the difference between flight path and movement of the aircraft ?
Thank you I was caught up o that question as well.
When the nose is pitched down, does that always mean it has a lower angle of attack then when it it pitched up?
Not necessarily as the angle of attack depends on the relative airflow which is related to the flightpath. I explain it further in this video: czcams.com/video/jo24pruCz4U/video.html
5/6 not bad
small correction the question asks about mean camber line twice instead of one being about the mean camber line and the chord line.
Questions 5 & 6
If you look closely, the wing in question 5 is different shape to the wing in question 6.
Very nice video
Thank you very much.
Very nice. What is the software for the animation part ^^?
Hi Hung, mostly done in keynote on a Mac.
@@flightclubonline love it. Keep up the great works :)
Thank you!
how come Project Wingman brought me here
Shouldn’t the answer to Q6 be the “curved line...”? As the mean camber line cuts the wing directly in half and requires the curve, however the chord line is straight.
Nope, this is a tricky question. If you examine the shape of the wing in Q6 you will notice that it's symmetrical.
It’s weird got me for a sec too haha
Last question, why it’s straight line
thanks for your video...but see question number 5 and 6 on quiz...that is not right.
Question 5 shows a different shape airfoil to question 6. Look carefully.
in question 3, why is answer 3 wrong?
What happens when the angle of attack increases????
Good question. Our video on stalling explains.
Lift increases drag also increases
I think last question has some mistake
No mistake. Have a closer look at the shape of the wing. Compare it to Q5.
you repeat the same question 5 and 6 but you differ in answe i think u ask chord line in question 6
No, Qs 5 and 6 are not the same: the shape of the wing is different.
Hello Pilots,
Do I understand it right that,
Stall will happen when you have a large angle of attack at relative low speed?
But
if, with the Same Angle of Attack, the speed is much higher, then stall
won't happen. Right? And the plane will climb up of course. Right?
If not right, Then how come that fighter jets and other acrobatic planes can climb straight vertically?
I suppose this is because of their high speed, which provides enough lift, no matter in what direction or angle they move.
So why can't normal plans in a critical angle of attack give full thrust to gain more lift?
The air is the same everywhere in the sky. Why behaves the air different if we want to fly in an angle which is not parallel to the horizon?
is just me or are these terribly worded test questions?
AAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks
