What is ktas?

KTAS, or knots true airspeed, is a measurement of an aircraft's speed through the air relative to the surrounding air mass. It is calculated by adjusting the indicated airspeed (IAS) for factors such as altitude, temperature, and pressure in order to determine the aircraft's true speed through the air.

KTAS is important for pilots as it provides a more accurate measure of an aircraft's performance, as IAS can be affected by varying atmospheric conditions. It is used for flight planning, navigation, and determining fuel consumption.

In general, higher KTAS values indicate faster speeds through the air, which can affect flight time, fuel efficiency, and overall performance of the aircraft. Pilots must take into account KTAS when planning their flights to ensure safe and efficient operation.
