Question 47 Deck Safety

70% to pass

CATEGORY I EPIRB's transmit on frequencies that are monitored by _______________.

A commercial radio stations
B private, commercial, and military aircraft
C orbiting satellites in space
D Both A & C
AI Explanation

The correct answer is C) orbiting satellites in space. Category I EPIRBs (Emergency Position-Indicating Radio Beacons) transmit on the international distress frequencies of 406 MHz and 121.5 MHz, which are monitored by orbiting satellites in the Cospas-Sarsat satellite system. This system is designed to detect and locate distress signals from EPIRBs, allowing search and rescue operations to be initiated. The other answer choices are incorrect because commercial radio stations do not monitor these specific distress frequencies, and private, commercial, and military aircraft do not directly monitor the satellite system that receives EPIRB signals.
