This man deserves heaven it is not difficult learn and understand the topics with you. Thank you!
John and Martha were technically my first flight instructors back in the days of Flight Sim 2002. I’ll never forget their impact on me and I’m sure a lot of other pilots.
best explanation i've heard so far! thank you!!!
Glad it was helpful!
Best teacher of aviation big up sir
I'm 48 years old in a&p school already got my general working on airframe atm. Thank you guys for having the BEST Video series ever invented for all these subjects. Seriously I love you guys!!
That's awesome, thanks so much!
This video and the clear force vectors explained it so well.
what I don't understand is why a stall on the upoer side of the wing makes the wing not produce lift since below the wing, air is still hitting the lower side pushing it up so shouldnt it?
Its more a case of that the wing is getting sucked up from the top of the wing ! When that does not happen its stalling !
From my understanding, the amount of upward force produced by high-pressure due to air flowing underneath the wingis far less than the low pressure force on the top side of the wing, which is sucking the wing up. When a stall does occur, it's when the airflow detaches from the top surface. The wing is still producing lift, but a fraction of what it was before.
From the video he states that when the airflow detaches "lift is destroyed", he could be more concise, I think a better phrase would be "lift is significantly reduced".
Its pretty simple actually. When you lose low pressure air on the upper camber on a stall, lift is not generated anymore. Why?
Simply because lift is generated when there is pressure differential. If there’s no low pressure on the upper camber on high Angle of attacks, there is no pressure differential anymore. Thus, no lift.
thank you. You are such a great teacher, makes all seem so simple after watching it. :)
Very easy to understand, great explanation
Glad it was helpful!
Crystal clear. Cheers.
This video clearly explains the foreign language I read from textbooks :P
Now that's what I call learning.
Thank you, beautiful presentation
Our pleasure!
this was a great video, thank you so much!!
You're so welcome!
Thank you so much! awesome content
You're very welcome!
Navy pilot student here. Great explanation, thank you very much
You got it! Thanks for watching.
Thanks ❤️ it really helps me to understand 🤗
great video!
This guy is great
Very well explained
Glad it was helpful!
Aerodynamics is such an amazing subject in order to understand the basics.
Sir i don't know whether you'll read my comments or not......
Thank you so much for making this video ☺️🙏.
So nice of you!
After critical angle of attack coffecient of lift decrease?
And that is how you teach.
It's probably a stupid question but how do planes keep from stalling when ascending to cruising altitude? Or does it just keep to the the angle it has at takeoff?
Remember it is the angle between the relative wind and the chord line, not the horizon and the chord line.
@@lawrencebell8837 oh ok thanx for that knowledge man, I've been an Aviation Super Freak for 30 yrs now so this is most definitely something I should have a deep understanding of
What if we deploy flaps, what will be the change in angle of attack?
So often we see examples in the various compilation plane crash videos, too slow or hard banking at low altitude the poor plane just ceases to fly...... :-(
But the Velocity is dependent on the density of the air. In which case , the stall speed must vary at different altitudes. Can you clarify , please?
What I understood is the relative speed of the aircraft with respect to the ground is increased but the airspeed remains the same as it requires the same amount of pressure to calculate the airspeed.
hmm... so here he says at critical AOA the wing stalls.. but on my commercial test prep it says at critical AOA the wing still has smooth airflow, weird..
here is the question + the correct answer as it appears on the practice exam:
"94. Reaching the critical angle of attack means that the wing will ___"
*A. continue to have smooth airflow.*
B. stall.
C. have separation of airflow over the trailing edge.
Big big big confusions made by a lot of SPs. Relative airflow IS NOT the horizon. Your pitch angle is not necessarily your AoA.
Just know that relative airflow can change... And it operates in the parallel direction of the direction of movement, in the opposite direction.
acute angle is angle of attack angle of attack is acute angle acute angle is angle of attack
It is not air molecules...it's water molecules that are heavier than air.
Nitrogen(N2) and oxygen(O2) is heavier than water(H2O).
Angle of attack= USSR💀(dog flight)
For them stall doesn't exist
noyyyy
