Integrated and Modular Systems for Commercial ... - Nonstop Systems

Why change avionics? (cont’d)
•Airframe manufacturer (cont’d):
� more demanding systems characteristics:
– maint. deferred for 100-200 hrs or even until C-check
(fault tol., spare-in-box)
– fault-tolerance transparent to application s/w
– brick-wall partitioned applications
– all Aps & Ops software: on-board loadable/upgradeable
– 100% fault detection and complete self-test (w/o test equipment)
– 95% reliability over a/c life (60k-100k hrs)
- more, better, cheaper, faster -
