MS,
Airbus BUSS, as it named it is a back up system, only displays in case of triple failure of ADRs; and better than nothing.
I respect definitely your posts in this forum, however I disagree with the comment "Vmo/Mmo is dependent on weight." No it is not. it is a fixed speed regardless of weight. Below crossover altitude where dynamic pressure is dominating it is given as KEAS; above crossover altitude where shock waves are dominating it is given as Mach No.
It was old days I do not remember all details about T 38, but another thing I remmeber, if Flaps are Up, the green light was on at L/D max. We never used for descent but in the worst case L/D max speed can be used as descent speed safely, takes too much time though.
I agree with you, for the accuracy of AOA. In one of the bulletins of A 320, it mentions 0.1 degree AOA error causes around 3t weight calculation error
(some systems are fed with calculated weight depending on AOA, CG, THS and N1)
