- 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 ... from test flights conducted in a new aircraft, under normal operating conditions while using average 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…
- 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 ... altitude, lowering the landing gear, or lowering the 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…
- 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 required to maintain level flight, or 2. The aircraft climbs by converting airspeed (KE) to altitude (PE). As an example of factor 1 above, an aircraft with an engine capable of producing 200 horsepower (at a given altitude…
- Chapter 4. FLIGHT PLANNING › 4-3. PIREP CAUTIONS › b. No Icing Reported
Icing Reported. An aircraft encountered icing, but the pilot did not report it. Pilot workloads might prevent a pilot from making a report, particularly when making an approach. An aircraft might also encounter icing conditions that are more serious than ... those are reported in any recent PIREPs in the given area. There are several possible reasons for this: (1) Icing conditions are extremely variable in space and time, as previously noted. PIREPs depend on the type and ice protection…

Figure 11-19 illustrates the general effect of wind by the percent change in takeoff or landing distance as a function of the ratio of wind velocity to takeoff or landing speed. The effect of proper takeoff speed is especially ... distances are critical. The takeoff speeds specified in the AFM/POH are generally the minimum safe speeds at which the aircraft can become airborne. Any attempt to take off below the recommended speed means that the aircraft could stall, be difficult…
