Almost all data displayed (except the detailed distribution across the forward, mid and aft distribution assemblies) is meaningful and reflects the systems running aboard the Shuttle as well as the position of the bus connector and tie switches. | Almost all data displayed (except the detailed distribution across the forward, mid and aft distribution assemblies) is meaningful and reflects the systems running aboard the Shuttle as well as the position of the bus connector and tie switches. | ||

[[File:Shuttle avionics cryo.jpg|600px|CRYO SYSTEMS display of the Space Shuttle]] | |||
Cryogenic stores of hydrogen and oxygen are carried aboard the Shuttle both to provide reactants for the fuel cells and to provide water for the environment system. The state of the cryogenic tanks (temperature, pressure and quantity) can be monitored via the cryo system display. | |||
Most of the data displayed is generic as there are no failure modes for the cryo system implemented, i.e. it is assumed that temperatures and pressures are always nominal. The only non-trivial reading is the quantity of the stores. | |||
