- 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 9: Techniques of Flight Instruction › Demonstration-Performance Training Delivery Method › Learner Performance and Instruction Supervision Phases
Demonstration Phase The instructor demonstrates the actions necessary to perform a skill and may describe the actions simultaneously. The instructor avoids extraneous activity as much as possible so that learners get a clear understanding of the task ... closely conform to the explanation, this deviation should be immediately acknowledged and explained. Figure 9-6. The demonstration-performance method of teaching has four essential phases. Learner Performance and Instruction Supervision Phases As discussed in Chapter 5, The Teaching Process…
- 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…
- 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 5: Rotorcraft Flight Manual › Performance (Section 5)
Performance (Section 5) The performance section contains all the information required by the regulations and any additional performance information the manufacturer determines may enhance a pilot’s ability to operate the helicopter safely. Although the performance section ... limitation section and is therefore not a limitation, operation outside or beyond the flight-tested and documented performance section can be expensive, slightly hazardous, or outright dangerous to life and property. If the helicopter is certificated under 14 CFR part…
