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

    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 ... these speeds when planning for takeoff. ⦁ VS —stalling speed or minimum steady flight speed at which the airplane is controllable. ⦁ V1 —critical engine failure speed or takeoff decision speed. It is the speed at which the pilot is to continue…

    visibility, distance from cloud, and ceiling meeting or exceeding the minimums specified for VFR. VLE. Landing gear extended speed. The maximum speed at which an airplane can be safely flown with the landing gear extended. VLO. Landing gear operating speed ... maximum speed for extending or retracting the landing gear if using an airplane equipped with retractable landing gear. VMC. Minimum control airspeed. This is the minimum flight speed at which a light, twin-engine airplane can be satisfactorily controlled when…

  • Chapter 16: Transition to Jet-Powered Airplanes › Speed Margins

    this can be an advantage in certain descent profiles, it is a handicap when it is necessary to lose speed quickly. The lack of propeller drag, along with the aerodynamically clean airframe of the jet, are new to most pilots ... into jets. In level flight at idle power, it takes about 1 mile to lose 10 knots of airspeed. Speed Margins Maximum speeds in jet airplanes are expressed differently and always define the maximum operating speed of the airplane, which…

  • Chapter 16: Transition to Jet-Powered Airplanes › Jet Engine Landing › Approach Speed

    There are strong relationships between trim, speed, and power in most jet airplanes, and it is important to stabilize the speed in order to minimize those other variables. ⦁ The optimum descent rate is dependent upon ground speed. A rule ... thumb is to multiply half of ground speed by 10. For example, a 130-knot ground speed should result in a (65 times 10) 650 feet per minute descent rate. Typical descent rates fall between 500 and 700 feet…

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

    safe OEI flight. Terms and Definitions Pilots of single-engine airplanes are already familiar with many performance “V” speeds and their definitions. Twin-engine airplanes have several additional V-speeds unique to OEI operation. These speeds are differentiated ... notation “SE” for single engine. A review of some key V-speeds and several new V-speeds unique to twin-engine airplanes are listed below. ⦁ VR —rotation speed—speed at which back pressure is applied to rotate the airplane…
