APPROACH SPEED Meaning and
Definition
-
Approach speed is a term primarily used in the field of aviation to describe the airspeed of an aircraft when it is about to land. It refers to the speed at which an aircraft should descend towards the runway during the final phase of its approach, typically before the flare and touchdown. The approach speed is a critical parameter that must be carefully calculated and adhered to by pilots to ensure a safe landing.
The specific approach speed varies depending on several factors, including the type and weight of the aircraft, wind speed and direction, runway conditions, and other environmental factors. It is usually given as a reference speed in terms of knots (nautical miles per hour) or a multiple of the aircraft's stall speed. The aim is to maintain a controlled descent rate and sufficient forward airspeed to maintain lift while allowing for a smooth and safe touchdown.
The concept of approach speed is integral to the proper execution of an aircraft landing, as a higher or lower speed than required can lead to undesirable consequences. If the approach speed is too high, the aircraft may float above the runway, leading to a longer landing distance or even a runway overrun. Conversely, if the approach speed is too low, there is a risk of the aircraft stalling, resulting in a loss of control and a potential crash. Therefore, the determination and precise control of the approach speed are of paramount importance for a successful and safe landing.

Etymology of APPROACH SPEED
The word "approach" comes from the Old French word "approcher", which was derived from the Latin word "appropiare". "Appropiare" is a combination of the Latin prefix "ad-" (meaning "to") and the Latin word "propinquus" (meaning "near"), giving "approach" the meaning of moving closer or nearer to something.
The word "speed" originated from the Old English word "spēd", which also has Germanic origins. It originally referred to success, prosperity, or good fortune. Over time, the meaning shifted to encompass the notion of rapid motion or swiftness.
When these two words are combined to form "approach speed", it refers to the velocity or rate at which an object or entity approaches a particular point, object, or condition.
