Final answer:
The use of PEDs on USAF aircraft is regulated and varies by aircraft and mission. It is guided by safety and security policies, distinct from FCC Chairman Kevin Martin's commercial telecommunications proposals.
Step-by-step explanation:
The use of Portable Electronic Devices (PEDs) on United States Air Force (USAF) aircraft is subject to regulations that ensure safety and security. While FCC Chairman Kevin Martin proposed the allowance of PEDs on certain unlicensed radio frequencies or 'white spaces', this is more relevant for commercial telecommunications rather than the specific rules that govern military flights. For security reasons, radiation-emitting devices can trigger detectors at airports, and individuals recently treated with radioisotopes may require special permission to fly on commercial airlines. It is important to consult with authorities regarding the current policies on the specific aircraft in question as these can vary by mission and type of equipment.
