The FAA is seeking comments (due October 30) on passenger use of portable electronic devices (PEDs) in general aviation and airline operations. Operators are allowed to determine that PEDs don’t interfere with navigation and communication systems but, the FAA wrote, “this notice requests comments about key areas of policy and guidance that are used by aircraft operators when making these determinations. It also requests comments about other technical challenges for addressing the problems associated with determining if and when PEDs can be used.”
