Airline passengers irritated at having to turn off their devices could soon see some reprieve, with regulators set to allow wider use of gadgets in flight.

The Federal Aviation Administration is expected to relax the ban on using some types of personal-electronic devices at low altitudes, allowing passengers leeway during taxiing and even takeoffs and landings, according to industry officials and draft recommendations prepared by a high-level advisory panel to the agency.

The FAA likely won’t make a formal decision on the matter until after it receives the final version of the advisory panel’s study, now delayed two months to the end of September.
