Calling for back-ups– innovating with DME performance

Since 2013, EVAIR (EUROCONTROL Voluntary ATM Incident Reporting) has been recording, and reporting on, GPS outages in Europe. Since 2013, these incidents have been increasing. The causes for these outages vary greatly - from Private Personal Devices (PPD) turned on too close to air traffic to radio frequency interference and spoofing - but the latest report published in February 2022 noted that most areas affected by these outages “are still those where political tensions exist.” The current situation in Ukraine is doing little to quell concerns over these repeated incidents; if anything, those are increasing in related air traffic spaces. The service bulletin reports several recommendations but the most important has been addressed to aircraft operators suggesting to avoid using as destination airports where only GNSS approach procedures are available.
