According to this article, my assumptions about the Boeing 737 MAX flight control system are (please correct me if I am wrong):
- The aircraft has two flight control computers (FCC)
- The aircraft has two angle of attack (AoA) probes
- The Maneuvering Characteristics Augmentation System (MCAS) is implemented as a function of each FCC
- Data from the port AoA probe is supplied only to FCC 1
- Data from the starboard AoA probe is supplied only to FCC 2
- Only one FCC (FCC 1 or FCC 2) is active during each flight, with the other serving as a backup system
Assuming a situation where only the AoA probe used by the active FCC produced incorrect AoA information and thereby causes the MCAS to intervene while the other AoA probe is functioning correctly, would it be possible to either
- switch to the other FCC (which uses input data from the other AoA probe)
or
- switch the active FCC to use input data from the other AoA probe
and thereby prevent the MCAS from continuing to use incorrect AoA data?
