indicated airspeed

**indicated airspeed**

Indicated Airspeed (IAS) refers to the speed shown on an aircraft’s airspeed indicator, reflecting the dynamic pressure of the air flowing into the pitot tube. It is the primary reference for pilots during flight operations, providing essential information for maintaining safe flying speeds in various phases of flight such as takeoff, landing, and maneuvering. Unlike true airspeed, IAS does not account for factors like altitude or air temperature, but it remains a critical parameter for understanding aerodynamic performance and aircraft handling characteristics.
