Re: AFAIK
All the unapplied changes were those that required recertification. So yes, the additional sensor, or other changes, training etc etc could all help. All would need recertification.
It was not the $30 cost of the materials, the $80 cost of manufacturing or the $200 cost of fitting any sensors... or the millions in costs of making and designing a different airframe. It was the billions in cost of delays of development, sales etc from the time taken and needed for recertification. :/
