Some US GPS Jamming (it’s just a test)

If you’re flying the Great Falls area (KGTF) from now until March 6th, you’ll want to watch out for some GPS outages due to testing.

Right now, they’re testing daily from 1631z-20z, and the impact is all about how high you’re flying. You could lose WAAS, GBAS, and ADS-B.

See the ranges here:

If you do experience outages, you’re asked to only contact ATC if you’re in need of assistance, not to report any outages.

GPS Jamming at Cairo

Egypt notified airlines yesterday that GPS jamming is a concern to arrivals and overflights, and warned against conducting RNP/RNAV arrivals or approaches.

The jamming was announced on 24MAY, and is centred on Cairo Airport; the source is unknown.

Similar GPS jamming was conducted, at state level in that case, by North Korea last month, from five locations along the border with the South. South Korea, along with other Civil Aviation Authorities, are looking at an eLORAN based alternative as a backup.

Operators planning flights through the Cairo FIR should monitor NOTAMs for latest.
