method, that has recently been developed for
building high assurance systems. The SCR
framework includes a formal specification notation,
a state-based formal model, and assurance methods
useful for constructing systems that must provide
critical services in a secure, safe, timely, and faulttolerant
manner. To illustrate the application of
SCR to avionics systems, this paper presents an
SCR requirements specification of a small avionics
system, introduced by Miller in [I], which powers
on a device of interest when the altitude of an
aircraft falls below a specified threshold. To
develop a specification for this system, we follow a
four-step process. This process provides a
systematic approach to developing and organizing a
requirements specification of a nontrivial system.
