President Donald Trump's nominee to lead the Federal Aviation Administration says safety will be his top priority if he is confirmed.

Former Delta Air Lines executive and pilot Stephen Dickson says US aviation has an enviable safety record over the past decade. But he says the industry is only as good as the last takeoff or landing.

In testimony prepared for a Senate Committee's confirmation hearing, Dickson said Wednesday that new technology such as aircraft automation and air traffic control systems can provide benefits. But they can also bring changes to a mature safety system that need to be managed carefully.

Dickson also says making sure the FAA keeps its standing as the world's top safety agency will be a priority if he's confirmed.

The FAA has faced criticism for approving flight-control software for the Boeing 737 Max. Two of the planes have crashed in the past year in Ethiopia and Indonesia, killing 346 people.
