Abstract

This paper presents an assertional-style verification of the aircraft landing protocol of NASA’s SATS (Small Aircraft Transportation System) concept [1] using the I/O automata framework and the PVS theorem prover. We reconstructed the mathematical model of the landing protocol presented in [2] as an I/O automaton. In addition, we translated the I/O automaton into a corresponding PVS specification, and conducted a verification of the safety properties of the protocol using the assertional proof technique and the PVS theorem prover.
