  • Chapter 13: Transition to Multiengine Airplanes › Engine Inoperative Flight Principles › ⦁ All propeller controls in the recommended takeoff position throughout VMC determination

    determination of VMC in certification is solely concerned with the minimum speed for directional control under a very specific set of circumstances, and not the optimum airplane attitude or configuration for climb performance. During dynamic VMC determination in aircraft certification ... cuts of the critical engine using the mixture control are performed by flight test pilots while gradually reducing the speed with each attempt. VMC is the minimum speed at which directional control could be maintained within 20° of the original…

  • Chapter 13: Transition to Multiengine Airplanes › Terms and Definitions

    single-engine airplanes operate differently during an engine failure. In a multiengine airplane, loss of thrust from one engine affects both performance and control. The most obvious problem is the loss of 50 percent of power, which reduces climb performance ... climb or maintain altitude in a light-twin may not exist. After an engine failure, asymmetrical thrust also creates control issues for the pilot. Attention to both these factors is crucial to safe OEI flight. Terms and Definitions Pilots…

  • Chapter 16: Transition to Jet-Powered Airplanes › Jet Airplane Takeoff and Climb › V-Speeds

    Airplane Takeoff and Climb The following information is generic in nature and, since most civilian jet airplanes require a minimum flight crew of two pilots, assumes a two-pilot crew. If any of the following information conflicts with FAA-approved ... center or pilot school curriculum, the FAA-approved procedures for that operator and/or training center/pilot school take precedence. V-Speeds The following are speeds that affect the jet airplane’s takeoff performance. The jet airplane pilot should understand…

  • Chapter 3: Basic Flight Maneuvers › Effect and Use of Flight Controls

    With the pilot’s hand: ⦁ When pulling the elevator pitch control toward the pilot, which is an aft movement of the control wheel, yoke, control stick, or side stick controller (referred to as adding back pressure), the airplane’s nose ... airplane. Think of this movement from the pilot’s feet to the pilot’s head. ⦁ When pushing elevator pitch control toward the instrument panel, (referred to as increasing forward pressure), the airplane rotates the nose forward relative to the pilot…

  • Chapter 13: Transition to Multiengine Airplanes › Low Altitude Engine Failure Scenarios › Control

    Landing Gear Control Selected Up, Single-Engine Climb Performance Adequate If the single-engine rate of climb is adequate, the procedures for continued flight should be followed. [Figure 13-20] There are four areas of concern: control, configuration, climb ... checklist. Figure 13-20. Landing gear up—adequate climb performance. Control The first consideration following engine failure during takeoff is to maintain control of the airplane. Maintaining directional control with prompt and often aggressive rudder application and STOPPING…

  • Chapter 13: Transition to Multiengine Airplanes › Engine Inoperative Flight Principles › Derivation of VMC

    They also describe the conditions used to determine the manufacturer's published speed. Historically, in aircraft certification, dynamic VMC has been determined under the following conditions outlined in historical 14 CFR part 23, section 23.149: ⦁ Maximum available takeoff power initially ... each engine (section 23.149(b)(1)). VMC increases as power is increased on the operating engine. With normally aspirated engines, VMC is highest at takeoff power and sea level, and decreases with altitude. With turbocharged engines, takeoff power, and therefore…
