Lawmakers who want tougher standards for evacuating aircraft in an emergency have criticized the Federal Aviation Administration for what they consider unrealistic simulations, and now they are calling for a do-over of current evacuation tests.
Decades-old federal rules require that planes be designed so that passengers can escape the cabin within 90 seconds in case of fire or some other emergency, even with half the exits blocked. Critics say the FAA has been lax in ensuring that today's airliners — with more seats and narrower rows — meet that standard.
