What you’ll learn
- Forces, not magicFour forces and lift; wing ≠ balloon.Stand by a runway before you let a wing mean a balloon.
- Pay drag; steer the vectorStall, thrust, drag, banked turns.Ask what happens when angle of attack goes too far.
- Keep the balloon honestRefuse antigravity myths; notice wing-as-balloon.Tonight, notice one flight headline that tried to mean a balloon.
Questions this course answers
What does it mean when the four forces balance in straight, level flight?
Zero net force means no acceleration; weight, lift, thrust, and drag remain real.
Put a normal banked turn idea in order.
Tilted lift turns the airplane; rudder coordinates yaw.
Why can a glider remain airborne without an engine?
In a steady glide, weight's forward component balances drag while the wing produces lift.
