Four Forces of Flight
What is lift, weight, thrust and drag?
These are the two types of stability.
What is Static and Dynamic?
This is the airflow that is parallel and opposite of the flight path of the airfoil.
What is relative wind?
This aircraft system controls "thurst"?
What is a propeller?
These are the two types of drag.
What is parasite and induced drag?
This is the chord line of the wing and the relative wind.
What is Angle of Attack
What is positive static stability?
This part of the lift equation can be changed by adding flaps?
What is surface area of the airfoil?
Thrust must be equal to what in straight and level flight.
What is drag?
These are the three types of parasite drag?
What is form drag, interference drag, and skin friction?
What is Bernoulli's principle?
The aircraft is more stable when we have a ____ CG.
What is forward CG?
These parts of the lift equation a pilot can control.
What is velocity, CL (AOA), and surface area (aka flaps)?
Weight must be equal to what in straight and level flight.
What is Lift?
Total drag is composed of what.
What is parasite and form drag?
Newton's 3rd law related to aerodynamics tells us what.
This is dependent upon the location of the wing (center of pressure) and the CG.
What is longitudinal stability (pitching)?
Denser air has more or less mass than less dense air.
What is more mass?
This component balances the aircraft in regards to weight?
What is taildown force? (
Induced Drag is a byproduct of what.
What is a byproduct of lift?
Changes in the center of pressure of a wing affect what part of the aircraft.
What is aerodynamic balance and controllability? (A wing's center of pressure moves forward and back with changing angles of attack, forward for high angles and back for lower. This changes the postion of the airloads on the wing and therefore changes the aircraft's aerodynamic balance and controllability.)
This is the tendency of the aircraft to turn into the relative wind (Yaw).
What is weathervane? (AFH)
The lift equation contains what variables?
What is velocity squared, coefficient of lift, surface area of the airfoil, and air density?
Overloaded aircrafts can cause what effect to takeoff and climb?
What is takeoff and climb might be difficult or impossible?
Ground Effect is approximately how high above the surface.
What is 1 wingspan height above the surface?
