  2. V speeds - Wikipedia

    en.wikipedia.org/wiki/V_speeds

    A single-engined Cessna 150L's airspeed indicator indicating its V-speeds in knots. In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. [1] These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification.

  3. Minimum control speeds - Wikipedia

    en.wikipedia.org/wiki/Minimum_Control_Speeds

    The minimum control speed during approach and landing (V MCL) is similar to V MCA, but the aircraft configuration is the landing configuration. V MCL is defined for both part 23 <FAR 23.149 (c)> and part 25 aircraft in civil aviation regulations.

  4. Airspeed indicator - Wikipedia

    en.wikipedia.org/wiki/Airspeed_indicator

    At a glance, the pilot can determine a recommended speed (V speeds) or if speed adjustments are needed. Single and multi-engine aircraft have common markings. For instance, the green arc indicates the normal operating range of the aircraft, from V S1 to V NO. The white arc indicates the flap operating range, V SO to V FE, used for approaches ...

  5. Maneuvering speed - Wikipedia

    en.wikipedia.org/wiki/Maneuvering_speed

    V A is the design maneuvering speed and is a calibrated airspeed.Maneuvering speed cannot be slower than and need not be greater than V c. [4]If is chosen by the manufacturer to be exactly the aircraft will stall in a nose-up pitching maneuver before the structure is subjected to its limiting aerodynamic load.

  6. V/STOL - Wikipedia

    en.wikipedia.org/wiki/V/STOL

    V/STOL aircraft types that have been produced in large numbers include the F-35B Lightning II, Harrier and V-22 Osprey. A rolling takeoff, sometimes with a ramp ( ski-jump ), reduces the amount of thrust required to lift an aircraft from the ground (compared with vertical takeoff), and hence increases the payload and range that can be achieved ...

  7. Aircraft approach category - Wikipedia

    en.wikipedia.org/wiki/Aircraft_approach_category

    II-5-1-3 Pilots may not use a lower category than the one certified, but may choose to use a higher category for higher speed approaches. [2] The maximum permitted speed for visual manoeuvring is significantly higher than the threshold speed. Additional speed ranges are specified for other segments of the approach. [1]: Table II-5-1-2

  8. Piper PA-44 Seminole - Wikipedia

    en.wikipedia.org/wiki/Piper_PA-44_Seminole

    Piper PA-44-180 Seminole PA-44 landing Piper PA-44-180 Seminole. The Piper PA-44 Seminole is an American twin-engined light aircraft manufactured by Piper Aircraft. [2]The PA-44 is a development of the Piper Cherokee single-engined aircraft and is primarily used for multi-engined flight training.

  9. Javelin V6 STOL - Wikipedia

    en.wikipedia.org/wiki/Javelin_V6_STOL

    Since it uses a standard Piper Pacer airframe, the aircraft is made from welded steel tubing, covered in doped aircraft fabric. Its 32.00 ft (9.8 m) span wing employs a USA 35B airfoil, mounts flaps and has a wing area of 168.00 sq ft (15.608 m 2). The standard conversion installs a 230 hp (172 kW) Ford V6 powerplant, driving a fixed pitch ...
