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]
A windsock (a wind cone or wind sleeve) is a conical textile tube that resembles a giant sock.It can be used as a basic indicator of wind speed and direction, or as decoration.
The Battenberg course indicator is a mechanical calculating device invented by Prince Louis of Battenberg in 1892 for taking station on other vessels whose range, bearing, course and speed are known. By extension, it has a range of other functions related to relative velocity calculations.
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.
A basic airspeed indicator with the indicated airspeed (IAS) indicated in knots ("Kt" or "Kts" or "KIAS") -- the most common unit of measure for airspeed. Some airspeed indicators in aircraft prior to the mid-1970s indicate in miles per hour plus knots (1 knot = 1.15 mph) or kilometers per hour (1 knot = 1.85 km/h).
A pilot uses the VDA, and ground speed, to compute a rate of descent (from a table found in the U.S. Terminal Procedures Publication), which is flown using the Vertical velocity indicator. [1]: 4–22, 4–23 Aircraft approved for LNAV/VNAV minimums include the Boeing 737NG, 767, 777, the Airbus A300 and some ATRs. [1]: 4–26 [2]
Peter Thiel’s Valar Ventures has doubled down its bet on Velocity, which operates a revenue-based financing platform for e-commerce and direct-to-consumer businesses in India, just months after ...
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 ...
