The implementation of GNSS is precipitating the removal of certain ground based navigation aids. IFATCA is concerned that as these GNSS systems are subject to natural temporary degradation and unserviceabilities that there should not be a reliance on a sole means navigation system.
IFATCA Policy is:Unless failsafe procedures are in place, the removal of terrestrial navigation aids is neither feasible nor safe. The persisting vulnerabilities in navigational systems require the maintenance of a terrestrial navigation infrastructure. |
