Yeah, but we don’t do safety that way.
We weigh cost vs risk vs convenience and consider unexpected consequences.
EMAS was designed to address runways that could not economically meet the FAA’s post-facto RSA standards. It’s wasn’t designed to be especially effective at slowing and stopping planes.
The big picture is longer runways contribute more to public safety than EMAS. A 9000’ runway with no EMAS is probably safer than a 7000’ runway with 2000’ EMAS. And yes, for a heavy like a 767 you would need a very long EMAS … that might not work with smaller aircraft. Yeah, it’s complicated.
Why don’t we reduce Interstate speed limits to
35mph and make occupants wear helmets? Why do we let homeowners purchase ladders and use them without hard hats and OSHA oversight?
