Final preparation before the
Space Shuttle simulation

The Space Shuttle simulation begins its five-week
simulation in the VMS beginning on 9 February. We are in final preparation
stages now for this. Two weeks ago, on 26 January, we began our cab integration
process. This involves communicating between our math model of the Space
Shuttle aircraft and all the hardware we use during the simulation. We
make sure the communication links between our host computer and the cab
(the simulated flight deck where the astronauts will sit and fly) is working.
The control inceptors (stick, rudder pedals, brakes) are all checked as
are all of the buttons, switches, knobs, dials, and instruments in the
We are at the end of this process and everything
looks good to begin on Monday. We are finalizing our check cases that
ensure the computer is outputting the correct data. This simulation we
are investigating the hydraulic Auxiliary Power Units (APUs) of the orbiter.
We will study if getting more powerful APUs will make it easier for the
astronauts to land the Space Shuttle, especially if one or more of the
three APUs fail.
