Elements related to performance and limitations by explaining the use of charts, tables, and data to determine performance.

How to determine the following, as applicable to the class sought:

a. Accelerate-stop / accelerate-go distance

b. Takeoff performance [e.g., balance field length and Velocity, Minimum Control (ground) (VMCG)] 4

c. Climb performance

d. Cruise performance (e.g., optimum and maximum operating altitudes)

e. Descent performance

f. Landing performance

g. Performance with an inoperative powerplant for all phases of flight (AMEL, AMES)

h. Weight and balance and how to shift weight

Factors affecting performance, including:

to satisfy the requirement to select one knowledge element The References for each Task indicate the source material for Task elements. For example, in the Task element “Acceptable weather products and resources required for preflight planning, current and forecast weather for departure, en route, and arrival phases of flight such as:” (

b. Pilot technique

c. Aircraft configuration (e.g., flap setting)

d. Airport environment (e.g., runway condition, land and hold short operations (LAHSO))

e. Loading (e.g., center of gravity)

f. Aircraft weight

Aerodynamics and how it relates to performance.

Adverse effects of exceeding an airplane limitation or the aircraft operating envelope.

Effects of icing on performance.

Clean wing concept; deicing and anti-icing procedures, including use of appropriate deice fluid, hold- over tables, calculating hold-over times, and pre-takeoff contamination checks.

Air carrier weight and balance systems (e.g., average weight program). Air Transport Pilot (ATP) (AMEL, AMES).

Runway assessment and condition reporting and use of the Runway Condition Assessment Matrix (RCAM). (ATP)(AMEL, AMES).

Use of performance charts, tables, and data.

Airplane limitations.

Possible differences between calculated performance and actual performance.

Airplane icing and its effect on performance and stall warning.

Runway excursions.

Describe the airspeeds used during specific phases of flight.

Describe the effects of meteorological conditions on performance for all phases of flight and correctly apply these factors to a specific chart, table, graph, or other performance data.

Describe the procedures for wing contamination recognition and any deice/anti-ice procedures prior to takeoff. 5

Explain the adverse effects of airframe icing during all phases of flight. Describe any operating limitations for flight in icing conditions. If equipped, describe the procedures for deicing and anti-icing system use and their effects on performance.

Compute weight and balance, including practical techniques to resolve out-of-limits calculations for a representative scenario, as specified by the evaluator.

Determine the computed center-of-gravity is within the acceptable limits and the lateral fuel balance is within limits for takeoff and landing.

Demonstrate proficient use of appropriate performance charts, tables, graphs, or other data to determine airplane performance and limitations for all phases of flight.
