- Chapter 11: Aircraft Performance › Performance Charts
Performance Charts Performance charts allow a pilot to predict the takeoff, climb, cruise, and landing performance of an aircraft. These charts, provided by the manufacturer, are included in the AFM/POH. Information the manufacturer provides on these charts has been gathered ... piloting skills, and with the aircraft and engine in good working order. Engineers record the flight data and create performance charts based on the behavior of the aircraft during the test flights. By using these performance charts, a pilot…
- Chapter 11: Aircraft Performance › Performance › Climb Performance
Positive climb performance occurs when an aircraft gains PE by increasing altitude. Two basic factors, or a combination of the two factors, contribute to positive climb performance in most aircraft: 1. The aircraft climbs (gains PE) using excess power above ... that altitude. This leaves 70 horsepower available to climb. The pilot holds airspeed constant and increases power to perform the climb. As an example of factor 2, an aircraft is flying level at 120 knots. The pilot leaves the engine…
- Chapter 11: Aircraft Performance › Performance › Climb Performance Factors
Climb Performance Factors Since weight, altitude and configuration changes affect excess thrust and power, they also affect climb performance. Climb performance is directly dependent upon the ability to produce either excess thrust or excess power. Earlier in the book ... flaps all decrease both excess thrust and excess power for all aircraft. Therefore, maximum AOC and maximum ROC performance decreases under any of these conditions. Weight has a very pronounced effect on aircraft performance. If weight is added…

intake and supply. Figure 3-3. IMSAFE checklist. Aircraft Hazards “A” hazards can be classified in terms of both performance and equipage. Performance Aircraft performance hazards may include: • Fuel and Range–As previously described, fuel issues continue ... cause of general aviation accidents. Planning a flight to the aircraft’s maximum range magnifies this “A” hazard. Inaccurate calculations, changing conditions, or the aircraft’s failure to achieve “book” speeds and fuel consumption can lead to an incident…
- Chapter 7: Helicopter Performance › Factors Affecting Performance › Moisture (Humidity)
Factors Affecting Performance A helicopter’s performance is dependent on the power output of the engine and the lift produced by the rotors, whether it is the main rotor(s) or tail rotor. Any factor that affects engine and rotor ... efficiency affects performance. The three major factors that affect performance are density altitude, weight, and wind. The Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25 (as revised), discusses these factors in great detail. Moisture (Humidity) Humidity alone…
- Chapter 3b: Effects of Weather on Small Unmanned Aircraft Performance › Performance › Climb Performance Factors
Performance Performance is a term used to describe the ability of an aircraft to accomplish certain things that make it useful for certain purposes. The primary factors most affected by performance are the takeoff and landing distance, rate of climb ... ceiling, payload, range, speed, maneuverability, stability, and fuel economy. Climb Performance Factors Since weight, altitude and configuration changes affect excess thrust and power, they also affect climb performance. Climb performance is directly dependent upon the ability to produce either excess…
