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.
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 ...
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
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
The Piper PA-12 Super Cruiser is an American three-seat, high wing, single-engine conventional landing gear-equipped light aircraft that was produced by Piper Aircraft between 1946-48. The PA-12 was an upgraded and redesignated Piper J-5 .
In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).
The Piper PA-28 Cherokee is a family of two-seat or four-seat light aircraft built by Piper Aircraft and designed for flight training, air taxi and personal use. [2] The PA-28 family of aircraft comprises all-metal, unpressurized, single piston-engined airplanes with low-mounted wings and tricycle landing gear. They have a single door on the ...
In tests performed on a Cessna 182 and a Piper PA-28-235 Cherokee, independent reviewers have documented a loss of cruise speed of 1.5 to 2.0 kn (2.8 to 3.7 km/h). However, these losses are relatively minor, since an aircraft wing at high speed has a small angle of attack, thereby reducing VG drag to a minimum.
