Blog Editor’s Note: A good reminder for folks who like to think having VORs, DMEs, and ILS mean aviation is not dependent on GPS/GNSS.
We found the following lists in the article and notice particularly informative:
AREAS IMPACTED
- Kaliningrad region, surrounding Baltic sea and neighboring States;
- Eastern Finland:
- The Black Sea: and
- The Eastern Mediterranean area (including airspace in proximity to Cyprus, Turkey, Lebanon, Syria, Israel, and Northern Iraq).
POTENTIAL SAFETY PROBLEMS
- The loss of ability to use GNSS for waypoint navigation
- Loss of area navigation (RNAV) approach capability
- Inability to conduct or maintain Required Navigation Performance (RNP) operations
- Triggering of terrain warnings, possibly accompanied with audible ‘pull-up’ commands
- Inconsistent aircraft position on the navigation display
- Loss of automatic dependent surveillance-broadcast (ADS-B), wind shear, terrain, and surface functionalities
- Failure or degradation of aircraft systems that use GNSS as a time reference
- Potential airspace infringements and route deviations due to GNSS degradation.
EASA Warns That The Ukraine Conflict Could Impact GPS In Europe
The European safety body is warning operators of GPS interference as a result of the conflict.
The European Union Aviation Safety Agency (EASA) has just published a Safety Information Bulletin warning of the increase in the probability of issues regarding the use of Global Navigation Satellite Systems (GNSS) or Global Positioning Systems (GPS). The notice goes out due to the ongoing conflict in Ukraine following its invasion by Russian forces.
Preserving a safe environment for flight operations
The Safety Information Bulletin (SIB) issued by EASA, the body responsible for aviation safety oversight across the European Union, is aimed at the national aviation authorities of member states and air navigation service providers (ANSPs) as well as airlines.
