What is a critical function of the Combined Altitude Radar Altimeter (CARA)?

The Combined Altitude Radar Altimeter (CARA) plays a vital role in aviation by accurately measuring altitude over a wide range of conditions. This capability is essential for various flight operations, particularly in low-level flying where traditional altimeters might not perform optimally. By providing precise altitude measurements, CARA enhances situational awareness for the pilot, facilitates safe landing and takeoff procedures, and contributes to overall flight safety.

The ability to measure altitude effectively across different flight phases distinguishes CARA as a critical tool for pilots. It is particularly useful in scenarios where terrain varies significantly or when operating in adverse weather conditions where visibility is reduced. Accurate altitude information enables pilots to avoid obstacles, ensure safe separation from the ground, and execute precise maneuvers during flight.

This function is crucial for maintaining safe operation within regulated airspaces, during instrument approaches, and in complex air traffic environments. Thus, the emphasis on measuring altitude effectively confirms CARA's importance in modern aviation operations.
