What were their justifications, and why did the US carriers, no fools at tough negotiations, go for it but not others. And how did the FAA certification let it be optional rather than required. How often, for those that fitted it, did it operate ?
Southwest is retrofitting with AoA indicators as well. Believe American had them from the get-go. As I understand, the option is about $60K. Seems like noise level in terms of overall cost per airframe. Can't understand why that would even be an option and not included in the basic frame given the need for MCAS and total cost per airframe.
There was a report on Reuters awhile back after Lion indicating that WestJet, SilkAir, and flydubai also had AoA Diagree installed so at least some of the international carriers.
