Commercial Pilot (Airplane)
Performance & Limitations Lesson Plan
The Commercial Pilot (Airplane) Performance and Limitations Lesson Plan covers the knowledge, risk management, and skills associated with operating an airplane safely within the parameters of its performance capabilities and limitations.
Commercial Pilot (Airplane) Performance & Limitations Lesson Plan
Commercial Pilot (Airplane) Performance & Limitations Lesson Plan Introduction
-
Attention Getter:
- Research a mishap case study:
- Discuss how the initial conditions developed into an incident/accident/mishap
- Relate similar personal experiences of the same type of incident/accident/mishap
- Consider incorporating a case study as a guided scenario
-
Motivator:
- Aerodynamics is the branch of dynamics dealing with the motion of air and other gases, which gives us the performance we need to fly.
- Understanding basic aerodynamic concepts is essential to understanding the operation of the components and subcomponents of an aircraft.
- The principal aerodynamic concepts are that of the four forces that affect aircraft.
- It can be associated with the forces acting on an object in motion through the air or with a stationary object in a current of air.
- Several factors affect aircraft performance, including the atmosphere, aerodynamics, and aircraft icing.
- Pilots need an understanding of these factors to provide a sound basis for anticipating aircraft response to control inputs, which come in the form of performance.

Commercial Pilot (Airplane) Performance & Limitations Lesson Plan Guided Scenario(s)
- What happens to the AOA if while in straight-and-level flight, a pilot pushes forward on the control stick, pulls backward?
- What happens to the AoA if while in straight-and-level flight, a pilot pushes forward on the throttle? pulls backward?
- What factors can the pilot control to change the amount of lift an aircraft has? Weight? Thrust? Drag?
- The pilot is ready to taxi, applying power to start moving
- What must the pilot do with the power after the aircraft starts moving?
- What principle requires the pilot to change the power setting?
- After completing a weight and balance, the pilot realizes the aircraft is within tolerance, but the center of gravity tends aft
- How should the pilot expect stall speed to change? What if the center of gravity tends forward?
- Why does a heavy aircraft requires more takeoff distance? Can a pilot do anything to shorten this disance? If so, what? and at what cost?
- The pilot mounts a weather radar pod on the wing, what type of drag can be expected?
- The interaction between the pod and the natural form of the wing is considered what kind of drag?
- The wing it is mounted has several imperfections, rivets, etc. what kind of drag is characterized by these features?
- What sort of performance changes would be expected by such a modification?
- As an aircraft is accelerating down the runway, it is actually increasing it's drag, how is this possible?
- While in the traffic pattern, the pilot finds themselves "behind the power curve." what does this mean?
- While landing, the pilot experiences what feels like a cushion of air beneath the wings. What is this phenomena?
- When could the pilot expect to feel this cushion?
- What is causing this anomaly?
