( CNN ) -- Do you really turn off your smartphone , tablet or computer before takeoff and landing ? Despite flight attendants telling passengers to power off , some people admit they do n't always shut down their devices . Nearly one-third of passengers say they have accidentally forgotten to turn off their smartphones and other electronic devices in flight , according to this week 's joint study by the Airline Passenger Experience Association and Consumer Electronics Association . While more than 90 % agree those flight attendant directions to turn off devices are clear , 59 % say they always turn their devices completely off and 21 % say they switch their devices to `` airplane mode . '' Some 5 % say they sometimes completely shut down their devices . Many travelers also admit they do n't actually understand when they can use those devices . More than 40 % wrongly believe they can use devices while taxiing to the runway , more than 30 % in the air before reaching 10,000 feet and 26 % on a flight 's final descent . Almost every adult passenger who travels with portable electronic devices carried at least one such device on board , and nearly two-thirds used them in flight , the study found . Debate continues over electronic gadgets on planes . `` Airline passengers have come to rely on their smartphones , tablets and e-readers as essential travel companions , '' said Doug Johnson , vice president of technology policy at the Consumer Electronics Association , in a statement . `` Understanding the attitudes and behaviors of passengers that are using electronic devices while traveling will help the FAA make informed decisions . '' The study results were shared with the Federal Aviation Administration , according to an Airline Passenger Experience Association website posting . An FAA representative declined to comment on the study results . Hints of how the FAA might change the current rules regarding electronics in the air may come as soon as this summer . The FAA set up a working group in August to study the issue of portable electronics on flights and make suggestions for changes . `` The Aviation Rulemaking Committee continues to have regular meetings and teleconferences , '' said an FAA representative via e-mail . `` We expect their report and recommendations shortly after the group finishes its work at the end of July . '' Both the FAA and Federal Communications Commission regulate electronics in the air . The FCC forbids the use of mobile phones using the 800 MHz frequency and other wireless devices on aircraft in flight because of `` potential interference to wireless networks on the ground . '' The FAA supports that in-flight restriction but does allow the use of cell phones while the plane is on the ground , at the gate or waiting for a gate -- but not when the aircraft is taxiing for takeoff . The FAA bans the use of wireless devices during flight because of `` potential interference to the aircraft 's navigation and communication systems . '' The FAA allows use of some non-transmitting electronic devices outside of critical phases of flight such as takeoff and landing . During those noncritical phases of flight , the airlines set their own policies regarding passenger use of non-transmitting electronic devices .
