Techs will have to visit each aircraft. It not 100% software fix. Warning light will be added also for those that did not order the HUD.

I was under the impression that the AoA disagree "light" is an on-screen item: http://www.boeing.com/resources/boeingdotcom/commercial/737max/updates/AOA_VaneIndicator_AoA_Disagree_lg.jpg http://www.boeing.com/resources/boeingdotcom/commercial/737m... Or does Boeing sell MAXes without that screen altogether? The Boeing update page (https://www.boeing.com/commercial/737max/737-max-software-updates.page https://www.boeing.com/commercial/737max/737-max-software-up...) says it is the "baseline primary flight display" , so sounds like it would be included in all MAXes already, so no physical change may be necessary.

  the physical light is a paid add-on. they’re adding it now through software for everyone.

  Aren’t they also retrofitting a second AoA sensor to those planes that didn’t have that option?

    So from what I’ve read (happy to be corrected) the very odd thing here is apparently all of the 737 MAXs do always have two sensors installed. This was purely a software difference as to whether the AoA disagree option was software enable. This feature cost more money but it seems it exists entirely in software. The indicator is even just drawn on the LCD displays, it’s not a special light on a panel. This blows my mind and reeks like other product management decisions I’ve faced in my particular industry where someone said “make that a feature we can enable so we can charge for it”. And they did charge more for it. Now everyone will get it free. Edit: here’s a source for the claim that there’s always two physical AoA sensors installed anyway: https://aviation.stackexchange.com/a/61109 https://aviation.stackexchange.com/a/61109
