In aviation, a variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI) – is one of the flight instruments in an aircraft used to inform the pilot of the rate of descent or climb. [1]
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).
In discussions of the takeoff performance of military aircraft, the term V ref stands for refusal speed. Refusal speed is the maximum speed during takeoff from which the air vehicle can stop within the available remaining runway length for a specified altitude, weight, and configuration. [19]
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.
In aviation, the maneuvering speed of an aircraft is an airspeed limitation at which the full deflection of the controls can be made at without risking structural damage. [ 1 ] The maneuvering speed of an aircraft is shown on a cockpit placard and in the aircraft's flight manual but is not commonly shown on the aircraft's airspeed indicator .
An airspeed indicator is a flight instrument that displays airspeed. This airspeed indicator has standardized markings for a multiengine airplane. Aircraft have pitot tubes for measuring airspeed. In aviation, airspeed is the speed of an aircraft relative to the air it is flying through (which itself is usually moving relative to the ground due ...
[4] [5] On the airspeed indicator of a twin-engine aircraft of less than 6000 lbs (2722 kg), the V MCA is indicated by a red radial line, as standardised by FAR 23. [ 4 ] [ 5 ] Most test pilot schools use multiple, more specific minimum control speeds, as V MC will change depending on the stage of flight.
The airspeed indicator (ASI) or airspeed gauge is a flight instrument indicating the airspeed of an aircraft in kilometres per hour (km/h), knots (kn or kt), miles per hour (MPH) and/or metres per second (m/s). The recommendation by ICAO is to use km/h, however knots (kt) is currently the most used unit.
