  • The FAA would let a booster take the lightning strike if nobody is in reach

    An October 5 FAA proposal would let a rocket on the way down skip lightning avoidance and hardening if physics keeps any debris inside a cleared area. It widens a practice the FAA granted reentries case by case, and its safety case rests on two legs: an engineered physics bound and a clearing the operator only has to describe.

  • The FAA wants the software to admit its own limits

    The FAA's newest condition for Skyryse's fly-by-wire R66 asks the aircraft to tell the pilot when the controls are running out of authority. The sentence is copied word for word from a 2018 Bell 525 rule, its key clause dates to the A320 in 1988, and it contains no number.
