Final answer:
Radar altimeters are designed to work within a range of 0 to 2,500 feet above the ground, but the actual operational range can vary depending on the radar system. Pilots should consult the manufacturer's specifications and guidelines for the radar altimeter in their aircraft.
Step-by-step explanation:
The altitude range that you can use your Radar Altitude hold depends on the capabilities of your radar system. In general, radar altimeters are designed to work within a range of 0 to 2,500 feet above the ground. These altimeters use radio waves to measure the distance between the aircraft and the ground, allowing pilots to accurately determine their altitude during flights.
However, it's important to note that the actual operational range can vary for different radar systems. Some advanced radar altimeters can operate at altitudes beyond 2,500 feet, while others may have a limited range. The specific altitude range of a radar altimeter is determined by factors such as the power and sensitivity of the radar system.
It's always crucial for pilots to consult the manufacturer's specifications and guidelines for the radar altimeter used in their aircraft to understand its altitude limitations and capabilities.
