Boeing would pay and the FAA as the enforcement agency would enforce it...

As mentioned, this isn't a Boeing-specific issue. This affects every major aircraft manufacturer, as well as a lot of smaller aircraft with aftermarket avionics. Surely Boeing isn't going to pay for the entire industry. Also, the FAA has no way of knowing if a particular aircraft operator is using a radio altimeter or not. Even if I have one installed, maybe I chose to switch it off. It's also possible I'm using it for situational awareness only (which is still allowed) and not using it to descend below legal approach minimums.

  Boeing pays for their upgrades. Airbus can pay for their upgrades. Douglas Aircraft pays for their upgrades after we revive the company.

Psst! Boeing isn't the only manufacturer affected. "Airbus has issued Flight Operations Transmission 999.0002/22 (01/10/2022) which describes the currently understood effects of radar altimeter anomalies. Guidance is provided for A320 family, A330, and A340 aircraft for handing these anomalies. "Embraer Flight Operations Letter 170-001/22 and Operational Bulletin 170-001/22 (01/02/2022): Describe the possible effects of C-Band 5G interference on its E170, E175, E190, and E195 aircraft. "The FAA has developed a process by which better performing radar altimeters that are able to reject 5G interference can be approved to operate without regard to the AD and NOTAMs. These Alternate Methods of Compliance (AMOC) approvals will be specific to a combination of aircraft model and radar altimeter model. The method of approval will take into consideration the performance of the aircraft/radar altimeter combination, as well as the location and power of the 5G transmitter in the vicinity of the airport. Therefore, the AMOCs are being issued with a list of airports where they are effective. As of 1/25/2022, FAA has approved AMOCs for several models of radar altimeters, installed on Boeing 717, 737, 747, 757, 767, 777, 787, and MD-10/-11; Airbus A220, A300, A310, A319, A320, A321, A330, A340, A350, and A380, Embraer 120, 170, and 190, all Canadair CRJ aircraft, some DeHavilland Canada DHC-8, and some ATR aircraft. These AMOCs are limited to certain airports and specific models of radar altimeters. Pilots should ensure that they have AMOC documentation for their aircraft and airport (e.g. in a dispatch release) before operating at an airport without regard to the 5G AD/NOTAM." https://www.alpa.org/resources/aircraft-operations-radar-altimeter-interference-5G https://www.alpa.org/resources/aircraft-operations-radar-alt...

  So some altimeters, manufactured by companies supplying all OEMs way hefore 5g was thing, have trouble with 5G now. There seems to be a solution for this old equipment, civil aviation moves on. For once no need to pick on Boeing here. Or on anyone else.

  I never said Boeing should pay for other companies upgrades. Maybe I could have said "the companies that own the airplanes"... but I'm not unaware that other companies are affected... that fact was even in the comment I replied too.

See my post about the ITU and international radio regulations.
