  • 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 5: Aerodynamics of Flight › Aerodynamic Forces in Flight Maneuvers › Forces in Climbs

    Figure 5-35. Normal, slipping, and skidding turns at a constant altitude. If the climb is entered with no change in power setting, the airspeed gradually diminishes because the thrust required to maintain a given airspeed in level flight ... insufficient to maintain the same airspeed in a climb. When the flight path is inclined upward, a component of the aircraft’s weight acts in the same direction as, and parallel to, the total drag of the aircraft, thereby increasing…

  • Chapter 11: Aircraft Performance › Performance Charts › Climb and Cruise Charts

    Climb and Cruise Charts Climb and cruise chart information is based on actual flight tests conducted in an aircraft of the same type. This information is extremely useful when planning a cross-country flight to predict the performance and fuel ... consumption of the aircraft. Manufacturers produce several different charts for climb and cruise performance. These charts include everything from fuel, time, and distance to climb to best power setting during cruise to cruise range performance. The first chart to check…

    refer to precise data sources (GIS database, etc.) specifically intended for OEI departure planning (see AC 120-91). 5. Climb gradients greater than 200 FPNM are specified when required to support procedure design constraints, obstacle clearance, and/or airspace restrictions. Compliance ... with a climb gradient for these purposes is mandatory when the procedure is part of the ATC clearance, unless increased takeoff minimums are provided and weather conditions allow compliance with these minimums. NOTE-Climb gradients for ATC purposes are being…

  • Chapter 11: Aircraft Performance › Performance › Rate of Climb (ROC)

    Rate of Climb (ROC) ROC is a comparison of altitude gained relative to the time needed to reach that altitude. ROC is simply the vertical component of the aircraft’s flight path velocity vector. For maximum ROC performance, a pilot ... achieve a maximum gain in altitude over a given period of time. Maximum ROC expedites a climb to an assigned altitude. This gains the greatest vertical distance over a period of time. For example, in a maximum AOC profile…

  • Chapter 13: Transition to Multiengine Airplanes › Short-Field Takeoff and Climb

    airspeeds. Other AFM/POHs do not provide separate short-field procedures. In the absence of such specific procedures, the airplane should be operated only as recommended in the AFM/POH. No operations should be conducted contrary to the recommendations in the AFM/POH ... making the initial climb over obstacles at VX and transitioning to VY as obstacles are cleared. [Figure 13-8] Figure 13-8. Short-field takeoff and climb When partial flaps are recommended for short-field takeoffs, many light-twins have…
