Note this is an "ask". If the FCC was serious, they could simply call their friends at the various federal procurement offices and tell them to only use "smartphones" that have FM radios active.

CHAIRMAN PAI URGES APPLE TO ACTIVATE FM CHIPS TO PROMOTE PUBLIC SAFETY
WASHINGTON, September 28, 2017--Federal Communications Commission Chairman Ajit Pai released the following statement today calling on Apple to activate the FM chips that are in iPhones to promote public safety:
"In recent years, I have repeatedly called on the wireless industry to activate the FM chips that are already installed in almost all smart phones sold in the United States. And I've specifically pointed out the public safety benefits of doing so. In fact, in my first public speech after I became Chairman, I observed that '[y]ou could make a case for activating chips on public safety grounds alone.' When wireless networks go down during a natural disaster, smartphones with activated FM chips can allow Americans to get vital access to life-saving information. I applaud those companies that have done the right thing by activating the FM chips in their phones.
"Apple is the one major phone manufacturer that has resisted doing so. But I hope the company will reconsider its position, given the devastation wrought by Hurricanes Harvey, Irma, and Maria. That's why I am asking Apple to activate the FM chips that are in its iPhones. It is time for Apple to step up to the plate and put the safety of the American people first. As the Sun Sentinel of South Florida put it, 'Do the right thing, Mr. Cook. Flip the switch. Lives depend on it.'"
