### How does the lift force stop increasing itself after a certain point?

It seems like the lift force would very quickly increase with airspeed (velocity). What I am unsure about is, what forces counteract lift to prevent it from reaching an extremely high value. Let's ...

### How does the lift force stop increasing itself after a certain point?

What I am unsure about is, what forces counteract lift to prevent it from reaching an extremely high value The airplane disintegrating is what would stop aerodynamic forces to grow too much. That's ...

### How does the lift force stop increasing itself after a certain point?

It seems like the lift force would very quickly increase with airspeed (velocity). That's right, provided that angle-of-attack stays constant. As the force of lift increases, won't it increase the ...

### How can I calculate the C.G height for an Aircraft?

You can calculate it the same way they calculate the vertical CG on astronauts in space suits. First calculate CG with the aircraft level. Then raise the nose of the aircraft so that the deck angle ...

### What are the flight formulas for aircraft

Your '2D' problem (altitude, downrange) is really a 3DOF problem, (adding a rotation -- pitch angle). Normal 3D flight is a 6DOF problem -- 3 positions, 3 angles. You will need to write the equations ...

### How does increasing the angle of attack increase the lift?

When the pitch of a plane increases (facing upwards), it has a positive angle of attack, and when it decreases to face downwards, it has a negative angle of attack. Well, sort of. Strictly speaking, ...

### How does increasing the angle of attack increase the lift?

when the pitch is increased, wouldn't the direction of the lift be facing backward, which would push the plane backward? No. By definition lift is the part of the aerodynamic force perpendicular to ...

### How does the lift force stop increasing itself after a certain point?

Nothing forces it from increasing quickly. At high airspeeds an airplane cruises with a small angle of attack to reduce its lift. If it suddenly increases the angle of attack its lift will go up ...

### How does the lift force stop increasing itself after a certain point?

There are actually 2 opposing forces to lift: gravity (directly) and drag (indirectly). Drag limits the speed one can go, thereby limiting the v$^2$ factor. But if lift does exceed weight, flight path ...
