Specifications of safety-critical real-time systems which are made with natural language has many disadvantages, such as contradictory, vague, ambiguous, and incomplete. The weakness in this specification will continue to the next stages, and will result the system failure. Formal methods allow the designer to determine the specifications of the system at different abstraction levels and verify the consistency of this formal specification before it is implemented. This study aimed to build and verify the formal specification of integrated modular avionics ('MA) health monitoring which use the AR'NC-653 standard using a model checking timed automata. The verified results will help developers to define logic effective of fault-tolerance, so as to guarantee the 'MA system can always available.
