for navigation, CAS is traditionally calculated as one of the steps between indicated airspeed and true airspeed; for aircraft control, CAS (and EAS) are the primary reference points, since they describe the dynamic pressure acting on aircraft surfaces regardless of density, altitude, wind, and other conditions.
An airspeed indicator for an aeroplane. Indicated airspeed is displayed on the black background (in this case both in knots (kn) and miles per hour (mph)). The pilot sets the pressure altitude and air temperature in the top window using the knob. Based on that, the white background scale in the lower left window moves to give true airspeed.
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).
Above 25,000 feet, the standard oxygen system cannot provide blood oxygen saturation enough for the pilot to function, so a full-body pressure suit must be used. [ 3 ] In a 1984 demonstration of their performance, an English Electric Lightning fighter aircraft used a zoom climb to intercept a Lockheed U-2 cruising at 66,000 ft, above the ...
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]
