hi Gums,
Don't get me wrong, the 1°/g is not an absolute value.
It is used to explain the elevator deflection criteria.
The massive THS/Stab for heavy transporters are 'slow' screw driven, therefore the elevators takes the short term pitch orders while long term orders are for THS to neutralize elevator deflection.
The exact logic inside the PRIMs is for obvious reasons hidden from public eyes.
Since it is 'gee' driven it won't need a speed signal to operate, (speed used for rates and gains) but if it is missing the IR(accelerometers) it definitely revert to DIRECT.
Already in the first
BEA report page 54/55 it was stated and explained why the system went in a latched ALTERNATE 2 law.
The figure and text is extracted from the FCTM.
