1. A method of performing a hazard analysis of navigation aid equipment using an external safety monitor, the method comprising:
- monitoring performance of the navigation aid equipment by interrogating the navigation aid equipment with a first sequence of signal pulses;
receiving, from the navigation aid equipment, a reply including a second sequence of signal pulses;
determining if the performance includes any improper performance of the navigation aid equipment by determining whether any time delay in the second sequence of pulses received from the navigation aid equipment is outside of a tolerance range; and
removing a signal from an antenna of the navigation aid equipment when any improper performance of the navigation aid equipment is determined.

17. A non-transitory computer-readable medium storing computer executable code for performing a hazard analysis of navigation aid equipment using an external safety monitor, comprising code for:
-
monitoring a performance of the navigation aid equipment by interrogating the navigation aid equipment with a first sequence of signal pulses; receiving, from the navigation aid equipment, a reply including a second sequence of signal pulses; determining if an improper performance of the navigation aid equipment is detected by determining whether any time delay in the second sequence of pulses received from the navigation aid equipment is outside of a tolerance range; and removing a signal from an antenna of the navigation aid equipment when improper navigation aid equipment performance is detected. - View Dependent Claims (18, 19, 20)
