Underwater tracking devices were put to use more frequently than usual in 2014, looking for downed airplanes in the sea.

Airline industry leaders and regulators want to improve airplane safety. They want companies to develop better, more dependable devices that can follow planes as they fly.

Searchers are still looking for Malaysia Airlines Flight 370. It disappeared over the Indian Ocean more than ten months ago. Nothing has been found. AirAsia Flight 8501 crashed into the Java Sea late last month. Voice and data recorders were found earlier this month. The search for all other parts of the airplane continues.

Air France Flight 447 crashed into the Atlantic Ocean in 2009. It took almost two years to find the flight recorders from the plane. Flight recorders store information about an airplane. They are often called "black boxes."

Michael Huerta is the administrator of the United States Federal Aviation Administration, or FAA. He says airplane crashes and disappearances are "extremely rare." But he and other aviation regulators are suggesting the airline industry make changes. The International Civil Aviation Organization, or ICAO, wants to create global airplane tracking standards. The organization is considering several possibilities.

One includes technology that cannot be disabled by anyone traveling on a plane. Another proposal is for the aircraft to report its location by satellite every fifteen minutes rather than every hour.

In some places, especially over oceans and in remote areas, there are times when radio transmissions from planes cannot be heard. The satellite company Inmarsat is offering to provide satellite reporting services to ICAO at no cost if the company's proposal is chosen.

Also, aviation officials in the United States have ordered plane manufacturers to replace black boxes that have batteries that operate for 30 days with batteries that work for 90 days. Airlines based in the United States will have these new black boxes in all of their planes by 2020.

Airplane manufacturer Airbus wants to put special flight recorders on some of its planes. These recorders would be ejected, or expelled, in the case of an accident. The company is negotiating with the European Aviation Safety Agency about placing the ejectable flight recorders on its two largest planes -- the A380 and the new A350.

If the negotiations are successful, Airbus would become the first commercial plane manufacturer to use the technology. They have been used for many years in military planes. After they are ejected, they transmit a call for help.

The ejectable recorders combine voice and information recordings. They record conversations between pilots and all other sounds made in the cockpit -- the area in a plane where pilots sit. And they record technical information such as air speed, engine performance and cabin pressure.

None of the new technology would prevent crashes. But they will help find downed planes more quickly. This might bring comfort to the family members of those who died.

Richard Aboulafia is an air travel expert with the Teal Group. He says more work should be done on preventing crashes. He says international agencies should share information about passengers and crew members.

"We need better information-sharing across borders. We need better human intelligence on who's on the passenger manifest and better sharing about that. We need better intelligence on crew personnel."

ICAO is expected to discuss the proposal to record a plane's location every 15 minutes at its planned meeting in Montreal, Canada, next month. The group has 191 member states. Not all of them put the group's standards in place.
