Preflight Discussion
Topic Be able to answer: Resources to study:
Aerodynamics Stability

  • Describe the stability characteristics of an airplane around each axis.
  • Describe the design features of your aircraft that contribute to its inherent stability.


  • Describe the different types of aerodynamic drag that occur during flight.
  • Why does induced drag increase as airspeed decreases?
  • Why does parasite drag increase as airspeed increases?
  • Draw a total drag curve and explain the relationship between induced drag, parasite drag, and airspeed.
  • Drag a power required curve and explain the relationships between power required to maintain altitude, airspeed, angle of attack and drag.
  • Why does it take more and more power to maintain altitude when flying at airspeed slower than the maximum endurance speed? Why is this called the backside of the power curve?

Slow Flight

  • Describe the aerodynamic forces during flight at minimum control airspeed.
  • Describe the procedure for entry and recovery from slow flight.
  • While maintaining slow flight, how do you cause the airplane to climb? Descend?


  • Describe flight operations in which stall awareness is needed.
  • Describe the angle of incidence.
  • Describe the relative wind.
  • Describe the angle of attack.
  • Draw the angle of attack in straight and level flight, climb, descent, and a level turn.
  • Describe what is happening to airflow over and under the wing during an aerodynamic stall
  • Describe the section of the wing in which a stall first starts to occur, and how the stall progresses across the wing
  • How does airplane weight affect the indicated airspeed at which the critical angle of attach is reached?
  • How does angle of bank affect the indicated airspeed at which the critical angle of attach is reached?
  • How does the amount of flap extension affect the indicated airspeed at which the critical angle of attach is reached?
  • Describe the flight control capabilities during a stall?
  • What are the signs of an impending stall?
  • How does an airplane recover from a stall?
  • Describe how to recover the airplane from a stall.
  • What is the purpose of power during a stall recovery?
  • Describe the procedure for entry and recovery from a power off stall.
  • Describe the procedure for entry and recovery from a power on stall.

Practical Knowledge Weight and Balance

  • Define empty weight, useful load and payload
  • How much does fuel weigh?
  • What is the empty weight of your airplane? Where did you obtain this?
  • What is the maximum weight for your airplane? Where did you obtain this?
  • What is included in the empty weight of your airplane?
  • What is a reference datum? Where is it located on your airplane?
  • What are the risks of a CG that is forward of the fore limit?
  • What are the risks of a CG that is aft of the fore limit?
  • What are the risks of an overweight airplane?
  • What are the benefits of a CG that is close, but not beyond the aft limit.
  • As fuel is burned during the flight, how does the CG shift?
  • Calculate weight and balance for this flight. Are we under max weight and within the CG envelope?

AFH 3BReview AFH Chapter 3 Basic Flight Maneuvers

Operation Expect to:
Preflight Inspection You will be conducting the preflight inspection. Your instructor will be asking you questions about the preflight issues you are looking for and to identify the location and purpose of different aircraft components.
Engine Start You will start the engine, using the appropriating priming procedure, check engine gauges and lean the mixture for taxi.
Taxi You will make the determination of the appropriate runway to use for takeoff. You will transmit the pre-taxi announcement on the radio, allow the airplane to roll forward with slightly more than idle power, test the brakes, and then taxi to the appropriate runway for runup.
Run-Up You will perform the run-up using the checklist. Your instructor will ask you about acceptable and unacceptable conditions for items checked during run-up.
Departure Brief You will give the departure briefing for this flight, with a departure plan to the practice area.
Before Takeoff Check You will perform the before takeoff check, including the collision avoidance scan. You will transmit the takeoff announcement on the CTAF.
Normal Takeoff You will perform the takeoff. After the airplane lifts off, establish a Vx climb, then after clearing obstacles, establish a Vy climb. Complete the 1,000 AGL checklist and turn the airplane to the on-course heading.
Shallow Climbing Turns You will then practice turns and rudder coordination as you climb up to the practice area altitude.
Level-Off, Cruise Check, Straight and Level Level the airplane off using the sequence Pitch-Power-Trim, starting approximately 50 ft prior to the discussed altitude. Be sure to anticipate that you will need to increase forward pressure on the yoke to prevent the airplane from attempting to climb again, reducing power only once the airplane has achieved the desired low cruise airspeed, and finally trimming the airplane once the airspeed and the elevator force transmitted to the yoke and felt in your hands has stabilized.
Climbing and Descending Turns You will practice climbing left and right 90 degree heading change turns and wing-levels (think of a climbing turn from upwind to crosswind) and descending left and right turns and wing-levels in the landing configuration (think base to final turns). You will use both an outside visual reference and a determined heading as your rollout reference.
Slow Flight You will perform the HASEL check. Your instructor will demo the entry into slow flight, shallow turns, climbs, descents, and then the recovery from slow flight. Pay special attention to the use of rudder needed to maintain heading during the entry and even just straight and level flight.

Your instructor will then coach you to transition the airplane from level cruise flight to slow flight, first in a clean configuration (flaps retracted) and then in a landing configuration (flaps extended).

Approach to Landing Stalls (Power Off Stalls) You will perform the HASEL check. Your instructor will demonstrate the setup, initiation and recovery from a power off stall. Your instructor then coach you perform the setup, initiation and recovery from the stall.
Approach Briefing You will be responsible for giving the approach briefing as you return to the airport.
Descending Turns You will practice making shallow left and right descending turns. Remember to watch the nose during these turns to determine the amount of rudder input needed to keep the nose pinned on a distant object as you roll the airplane from left to right and right to left.
Pattern Entry Your instructor will coach you through performance of the before landing and landing checklists, entry on the 45, and establishing downwind. You will transmit radio broadcasts on the CTAF to give your airplane’s location and intentions as you return to the airport, enter the pattern and land.
Normal Landing You will establish a stabilized approach, use of power to maintain a stable rate of descent. The instructor will assume control of the airplane prior to 200 AGL. You will call out when you feel the airplane should perform the level-off. Pay close attention to the nose attitude during the flare. You should be able to always see the departure end of the runway over the top of the nose.
Postflight Procedures You will taxi the airplane from the runway to the tiedown, executing the after landing checklist and shutdown checklists. Your instructor will help you push the airplane back into the tiedown, secure it, clean it and complete the post-flight section of the checklist.
