Primary Flight Controls are things like:
- Ailerons
- Rudder
- Elevator or Stabilator
Secondary Flight Controls are things like:
- Trim
- Flaps
- Spoilers
Bernoulli’s Principle is: when you increase the speed of air over the top of a wing, you decrease its pressure, thus generating lift.
Lift = Weight and Thrust = Drag anytime the airplane is in UNACCELERATED flight. In UNACCELERATED flight, the four forces are all EQUAL.
