Radar altimeters are frequently used by commercial aircraft for approach and landing, especially in low-visibility conditions (see instrument flight rules) and also automatic landings (autoland), allowing the autopilot to know when to begin the flare maneuver.

In civil aviation applications, radio altimeters generally only give readings up to 2,500 feet (760 m) above ground level (AGL).
