Abstract
Sensor selection status monitoring and maintenance logic for generating messages relating to intermittent and “in-range” faults are described. In one embodiment, a transition count is generated indicating a number of times the selection status number changes during a flight. A time duration table is generated indicating an amount of time a selection status number is recorded in each of its possible states during the flight. The maintenance logic utilizes outputs from the monitoring logic to generate maintenance messages.
Claims13
A method for monitoring a status of a sensor in an aircraft, said method comprising the steps of:
- generating a transition count indicating a number of times a selection status number changes during a flight;
- and
- generating a time duration value indicating an amount of time the selection status number is in each of its possible states during the flight.
Apparatus for monitoring a status of a sensor in an aircraft, said apparatus comprising a processor programmed to:
- generate a transition count indicating a number of times a selection status number changes during a flight;
- and
- generate a time duration value indicating an amount of time the selection status number is in each of its possible states during the flight.
