What is the primary method for detecting a lost pilot using the URT-140 Radio Beacon Set?

The primary method for detecting a lost pilot using the URT-140 Radio Beacon Set is through its transmission at 406.025 MHz. When activated, the URT-140 emits a distress signal on this specific frequency, which is standardized for emergency beacons. This frequency is picked up by the Cospas-Sarsat satellite system, which is designed to detect and locate emergency beacons in distress situations across the globe.

The significance of using 406.025 MHz lies in its global recognition and the capabilities of the satellite system to triangulate the signal's position. This enables faster and more efficient search and rescue operations since the location can be quickly relayed to rescue agencies.

In contrast, other methods mentioned, like visual searches by aircraft, ground radar tracking, or satellite analysis, while potentially relevant in certain circumstances, are not the primary or most effective methods for immediate detection of a lost pilot when a beacon is available. The direct communication and location-tracking capabilities of the 406.025 MHz transmission make it the most reliable option in such scenarios.
