Love your videos. This one was still a great video, however, I wanted to clarify a few things for aviators who might see this comment. During straight and level flight, thrust = drag and lift = weight. The four are not necessarily equal to eachother though. Also, the illustration you drew 8:44 with the aircraft in a bank, yes there is a horizontal component of lift because the aircraft is banked. However, the weight is still straight towards the center of the earth. The weight is not pulling you opposite of the lift. The weight is always going to pull you to the center of the earth, no matter what kind of lift the aircraft is making. Gravity doesnt change just cuz ur in a bank lol

“And what’s holding us back the FAA” classic man!! Haha

[@jetstreamgret2108]

Thanks for the first 2 videos, took the CFI checkride yesterday and passed!

[@fly8ma.comflighttraining199]

Congrats!!! Glad to hear it!

[@WarriorsfanDubnation]

FLY8MA.com Flight Training will you be my cfi??

[@realrussclarke]

Congrats! My check is June 27

[@Windtee]

Wing-rockin' congrats!

[@jetstreamgret2108]

Russ Clarke Best of luck!!!

[@TimAyro]

I am dreading this checkride. Every other checkride was easy. This one seems super intimidating. Appreciate these videos a lot!

[@omarnumba2]

how was it?

[@Tyler-pq6wp]

Did you pass

[@Vitoldinin]

Just one correction. All four forces are not equal in unaccelerated flight. Rather: Lift equals weight and drag equals thrust. Opposing forces are equal not all four. Cheers, aviators!

[@downwithreactionaries9031]

Some errors in the aerodynamics explanation: 1. The weight is always pulled into the center of earth, regardless of the airplane bank. In your explanation, weight can shift direction will confuse student. 2. induced drag will "INCREASE" if airspeed increase but AoA stays the same. The induced drag decrease as airspeed increase, is just because AoA can be decreased. This is Basic Ideas

[@realrussclarke]

The videos are great John passed my CFI Ride yesterday!

[@fly8ma.comflighttraining199]

Thanks for checking out our channel Russ!

[@seattleraf]

Used this as a refresher on aerodynamics for my ppl checkride 😂 Enjoyed the section at the end about CG.

[@fly8ma.comflighttraining199]

Glad this was helpful!

[@bemch1988]

Critical AOA is not stalling. Exceeding the Critical AOA is when the air separates and the wing stalls. It's called stalling AOA

[@borger86]

Hey John, thanks for making this video. Just wanted to point out when you were teaching about the horizontal component of lift your weight vector was pointed in the wrong direction. It should always be pointed directly to the ground or center of the earth in the same direction as gravity.

[@flightbug2902]

I wonder if he meant centrifugal force.

[@brandoncenteno1834]

Exactly what I came here to say 🤣 wonder if he got dinged for that. If weight was oriented like that inverted flight in the Cessna would be easy!

[@OrlandoemCasa]

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738. Maybe the principle was used for perfum bottles in France but I hadn't heard he manufactured perfums.

[@hassanalhwent3958]

Surprised how your videos doesn’t get millions of views. Great job

[@OrlandoemCasa]

Love, love, love.. The PacMan...explanation....

[@philconey11]

I'm on about my third watch-through preparing for my CFI initial. Here's hoping all goes well. I've made a full time job out of studying and preparing.

[@tobyshaner7905]

How did things go on your practical?

[@stephenyoungblood3683]

Great job. Keep in mind, gyroscopic procession doesn’t always give a “left turning tendency.

[@abbieamavi]

These videos are fantastic!! 😁 thank you

[@fly8ma.comflighttraining199]

Glad you like them!

[@Cheranetube]

Great video by the way! Not trying to sound critical in my last comment. Thumbs up!

[@AFO3310]

I have my initial CFI-A next wednesday the 7th. I've been teaching college aviation classes for a couple years and tutoring aviation students for the last 4 with my AGI cert. I have really positive reactions from my students when they're learning and my boss says I'm doing really well whenever she comes in to listen in on my classes for a review. I'm still nervous as heck for this checkride. This mock exam is great to listen to while I'm driving or doing other things around the house. I hear "do this, do that" and get some extra ideas but my teaching methods and lesson plans have been successful so far. Am I thinking too much about it?

[@solace2321]

Hey, how did it go? Mines coming up this week. Hope yours went well!

[@Windtee]

Great series!

[@Cheranetube]

Just watch out saying "The four forces are equal...they're not, or you would have a motor generating 2200lbs of thrust, which is your "weight". You could say "Opposite forces are equal in unaccelerated flight". Just a technicality, but important.

[@sjaviation]

The forces are equal, there isn't 2200lbs of drag.. but the wings are generating 2200lbs of lift.

[@Sam-ip9zd]

@@sjaviation how is drag equal to lift?

[@sirstanko]

good refresher ground training for my checkride next Tuesday!

[@fly8ma.comflighttraining199]

Good luck with your checkride!

[@passengerescobar]

I do not see the printable PDF link... Am I blind or is it not there?

[@1shARyn3]

LOVE that white board

[@1shARyn3]

Weight is always vertically downward. The G-force is generated due to centrifugal force (from turning acceleration) combined with the weight

[@jamesmulhall193]

Where did you get the model airplane?

[@PeterNSteinmetz]

That camber provides lift was known before the Wright brothers. Also, the order of subjects here should have been different. For example, why not cover 4 forces of flight, generation of lift, before talking about flight controls and trim? Lift does go like the square of velocity, but that is not a “exponential” increase, rather a quadratic increase.

[@wurzzzz]

I more cringed at the "travels longer distance" explanation of low pressure on top of the wing and the p-factor explanation.

[@husseinalmaliki7482]

thank you!

[@fly8ma.comflighttraining199]

No worries!

[@bernardofitzpatrick5403]

Awesome!

[@user-vs3zz3zi4s]

Great videos, anyone have the link for the pdf he is saying to print out?

[@veins101]

Wow first time I’ve see pac man used to explain lift generation. Need to check if the c172 had a dihedral. I was sure there was none.

[@Superxpninja]

The 172 actually has quite a bit of dihedral, look at the wings from the front of one wingtip

[@bataradharma3994]

Wich part that are talking about night operation and high altitude operation?

[@fly8ma.comflighttraining199]

later but on our site

[@badgerfishinski6857]

Isn't there Centrifugal Force in a turn?

[@fly8ma.comflighttraining199]

Centrifugal force is the "equal and opposite reaction" of the airplane to the change in direction and acts equal and opposite to the horizontal component of lift. This explains why, in a correctly executed turn, the force that turns the airplane is not supplied by the rudder.

[@arjan2856]

Air on top of the wing needs to travel a longer distance so it goes faster??? Are we seriously still teaching that?

[@user-fb6ns4zq2r]

Unfortunately yes......

[@CorrectContrarian]

@@user-fb6ns4zq2r While I really like his videos and content, I'm disappointed by this incorrect explanation of lift. The air accelerates over the top of the wing because the air is displaced going over the top of the wing causing an increase in velocity and a decrease in pressure. With a symmetrical wing(same distance top and bottom) if you incline the wing, you will create the "displacement" of air and increase the velocity across the top of the wing.

[@scottdubois5947]

For anyone who cares NASA has a whole page dedicated to why this is wrong: www.grc.nasa.gov/WWW/K-12/airplane/wrong1.html

[@davidb.7096]

@@scottdubois5947 I just read it, really interesting that the whole idea of Bernoulli's has been found as incorrect :o

[@KennyBates]

David B. The principle is still correct. What it states is that the theory of equal transit is incorrect. The displacement of air creates a greater velocity which equals lower pressure. Not “air on the upper surface has to keep up with the bottom surface.” The theory still stands

[@coreyballard8359]

Asking "does that make sense?" sorta sounds like a crutch....

[@planewire2153]

Corey Ballard well that gives a break for a student to ask a question

[@coreyballard8359]

Eli Smith there’s better ways to approach it in my opinion. Best way to gauge if a student understands is to ask them questions based on the topic. Vague questions like “does that make sense” give too much of an open end and a student will probably just say “yep”. Asking questions about the topic is a way to truly determine if what you’re teaching is making sense. Additionally, you should be teaching in a way that already makes sense to a student.
