@singlepilotops There isn’t one. The FAA does however have a standard passenger weight that includes your bags. Crew weighs more. But the airlines saying it’s an FAA rule are not entirely telling the truth. It’s airline policy.
@markreinoso@AmericanAir This is an FAA mandated secondary barrier. Used when flight crew needs to use the lav. Eventually all aircraft will have them.
@ECLOGITE110@SunWeatherMan Get the book “the shockwave rider”. It predicted this in the 60s. In the book they are called Delphi Pools. There’s a lot in there that applies today.
