This sounds like the "indicator" and "warning light" are not physical devices that must be installed at extra cost, but rather are software features that can be "activated" by changing some configuration file.
If so, then Boeing has blood on their hands. The active control system is already a cost-cutting hack. Charging extra for zero-cost safety features related to the new, unproven control system is an act of appalling greed.

- kayfox 7y agoSo, the AoA indication is a feature that can be activated for a fee (which most likely exists to cover costs of modifying the configuration from the base configuration, so imagine as an analogy a $2 fee for some really minor change to a car you ordered). The reason this is an option is that it requires additional training for the pilots, some airlines already have this training (American Airlines is one example) and theres no enabling it and then not training the pilots on it. As many have noted, AoA is not commonly used in non-military piloting in the United States, so its no surprise its not commonly ordered. I am also under the impression that the AoA Disagree indication was new on the 737 MAX, I haven't checked the 737 NG manuals for it.
