Double Standards - "better safe than sorry"

All electronic devices must be turned off during take off and landing as precaution ("why take the risk") against potential interference with communication and navigation systems of the aircrafts. This ban came from FCC and FAA.

Why does FCC allow CPTs on school grounds and in densely populated residential areas? "Why take the risk" where children are concerned?

Is it really dangerous to use a cell phone on a plane?

Excerpts:

A U.S. ban on airborne use of cell phones has been in place for 20 years because of concerns transmissions would interfere with cellular networks on the ground. While many airlines now offer Wi-Fi access via portable electronic devices from laptops to smartphones, cellular voice and data services on domestic airlines fall under that Federal Communications Commission ban.

The Federal Aviation Administration supports the ban, citing potential interference with aircraft communication and navigation systems. The FAA also advises airlines to make sure passengers turn off almost all portable electronic devices during critical phases of flight, below 10,000 feet. Airlines require electronics be turned off and stowed during takeoff and landing.

But airline passengers who have routinely neglected -- or forgotten -- to turn off their mobile phones without devastating consequences have to wonder, how dangerous can it be?

That turns out to be a tough question to answer, but those who've studied the rules sum it up as better safe than sorry.

The risk is small, "but why take that risk?" asked David Carson, a Boeing engineer who headed up a committee of aviation and electronics experts years ago to advise the FAA on the safety of Wi-Fi and cellular devices on planes.
