Salute!
How come we can not talk ancient processors over on Tech Log? Keep the management and political stuff here?
Good grief! The sfwe and object code for the MCAS function could be implemented on a 8088 or a Motorola cpu from the original Apple.
We flew the SLUF and the early Vipers with such, and less than a megabyte of RAM. Our non-volatile memory was maybe a few megs, and the same boxes were used in the lunar landing module. Sheesh.
The problem is not the CPU, nor the dedicated MCAS code. The problem is integrating a new function via the autopilot sfwe boxes, STS function, and who knows what else? No excuse for a complete re-write and still using grandfather cert, huh?
Basic aero still a big problem for this old pilot, so I am with folks that want to see raw MAX flight tests that have MCAS erased and look at the plots. Unless you go "full authority" FBW, the basic aero problems with the new motors and such cannot be mitigated with crude algorithms inserted in autopilot and STS functions such as we are led to see for MCAS.
Gums sends....
