Hello friends!
I'm unsure when the crew uses the THRUST ON pushbutton and when they decide to use the SPS THRUST DIRECT ON switch.
If I understand correctly, SPS THRUST DIRECT ON provides alternative backup mode to both CMC and SCS delta V modes? So when is there a need to use the TRUST ON pushbutton?
Another question is whether it is necessary to use the DIRECT ULLAGE pushbutton if the TRUST ON pushbutton is used? In what situation is there a need to use THRUST ON and DIRECT ULLAGE pushbuttons?
