What can the Combined Altitude Radar Altimeter (CARA) measure?

The Combined Altitude Radar Altimeter (CARA) is designed to provide accurate altitude readings across a wide range of elevations. Specifically, it can measure altitudes from 0 feet to over 50,000 feet, making it highly versatile for various flight operations. This capability is essential for aircraft that may operate at different altitudes throughout their missions, including both low-level flying and high-altitude operations.

The functionality of CARA encompasses both terrain following in low altitudes and standard altitude measurements at cruising flight levels, reflecting its dual capability in both civilian and military aircraft. This broad operational range ensures pilots receive crucial altitude information regardless of their flight segment, contributing to flight safety and operational effectiveness.
