  2. The two main types of drag are ______and ______.
  3. Parasite drag comes in three forms: ______, ______-______, and ______. Parasite drag ______as speed is increased.
  4. Drag due to lift is known as ______drag and ______as speed is increased.
  5. The angle between the ______line and the ______is the Angle of Attack.
  6. Bernoulli’s Principle states that as a fluid ______in velocity, it’s relative pressure will ______.
  7. An airfoil will stall regardless of its ______; It will always stall when it reaches the ______.
  8. The two types of Stability are ______and ______.
  9. Stability about the lateral axis is maintained by ______.
  10. Stability about the longitudinal axis is maintained by ______.
  11. If the Center of Gravity (CG) is too far forward, the airplane will be too ______and will be (more / less) recoverable in a stall. If the CG is too far aft, the airplane will be too ______and will be (more / less) recoverable in a stall.
  12. Directional stability, or stability about the vertical axis is maintained by ______.
  13. The lift equation is: ______.
  14. We practice Stalls in initial training to practice the ______.
  15. One type of stall is the ______stall and it simulates ______.
  16. Another type of stall is the ______stall and it simulates ______.
  17. We recognize a stall is occurring by ______.
  18. The left turning tendencies are ______, ______, ______, and ______.

True or False:

  1. Precession will happen 90 degrees opposite of the direction of rotation.
  2. If I place the airplane in a climb and it remains in that pitch attitude, it is displaying neutral
    static stability.
  3. Turbulence affects an airplane’s stall characteristics because it changes the direction of the
    relative wind.
  4. Maneuvering speed is lower as the weight increases.
  5. Newton’s third law says that every action has an equal and opposite reaction.
  6. Keel effect is due to the airplanes centerboard protruding into the relative wind as we fly.
  7. I can fill all of the seats in a Piper Archer with 200-pound people, have full fuel and still be under
    the weight limit.
  8. Load increases as bank angle increases.

Draw the four forces of flight acting upon this aircraft.

Short Answer Communications Questions:

  1. Before I am able to leave the ramp, I should get the ATIS, and then who should I contact? What Frequency?
  1. I’m in N282HP and holding short of runway 28R. I want to call Montgomery Tower for initial departure clearance. I want to go westbound to the Coast. What should I say?
  2. The Response is, “Archer 2HP, line up and wait runway 28R, traffic is a Skyhawk, midfield right downwind.” What does this mean? What is the absolute minimum that I am required to readback?
  3. What should I say to ATC if I have an emergency? ______
  4. What should I say to ATC if I need a moment to respond? ______
  5. What should I say to ATC if I cannot comply with their clearance? ______
  6. I am approaching Oceanside, an uncontrolled airport. After listening on the frequency, I note that Runway 24 is in use, right pattern. What should I say?

Spend some time exploring LiveATC.net. Go find an airport of your choosing and listen to ground and/or tower frequency. Pull up that airports “Airport Diagram” with a google search and try to see where each aircraft is going and what they’re saying to each other.
