Degraded Performance

Dual and Independent Operation

The FMS is operable when electrical power is applied to the aircraft. Power-up

tests are performed after any reset (restart of processing) due to either a long term

or short term power transient, or due to hardware or software problems.

Pilot-entered data is retained during power transients through battery powered

memory. However, if an FMC detects the same software problem four times

within five minutes, and the FMS flight phase is not descent or approach, then all

pilot-entered data will be automatically cleared during a long term reset. This

automatic reset is generated to prevent the FMC from latching fail. A latch failure

is a complete halt of processing, recoverable only by cycling the circuit breaker.
