How many hours can a radio beacon transmit a distress signal?

• A. 24 hours
• B. 48 hours
• C. 72 hours
• D. 6 hours

Answer: (B)

The amount of time a distress radio beacon can transmit is designed to give search and rescue teams enough opportunity to detect, locate, and reach the distressed location. In aviation and maritime distress systems, beacons are specified to operate for about 48 hours after activation. This endurance balances battery capacity and the need for reliable, long-duration signaling across satellite networks and ground search efforts. If the beacon could only transmit for a shorter period, there’s a greater risk of losing track of the signal before rescuers arrive; a longer duration isn’t typically required by the standard and would demand more power and weight. So, 48 hours is the standard answer because it provides a practical window for successful rescue efforts.
