After years of very restrictive rules on using computers and gadgets on airplanes, the Federal Aviation Administration, working with the Aviation Rulemaking Committee, is examining the safety issues and looking at the possibility of relaxing some of the rules.
On the FAA's Facebook page they posted;
We recognize consumers are intensely interested in the use of personal electronics aboard aircraft. That is why we tasked a government-industry group to examine the safety issues and the feasibility of changing the current restrictions. At the group's request, we have granted a two-month extension to complete the additional work necessary for the safety assessment. We will wait for the group to finish its work before we determine next steps.
It's unlikely, however, that people will have access to cellular networks while on the planes, but you may finally be able to play Tetris on your phone while waiting to take off, without being viewed as a criminal by the airline employees on board. The results of the re-evaluation should be released in a couple of months so we will find out relatively soon on what the updated restriction will be.
