Europe squawks 7600 on ops in the Eastern Med

As we reported last month,  Eurocontrol published a ‘Rapid Alert Notification’ on their website regarding imminent air strikes into Syria.

“Due to the possible launch of air strikes into Syria with air-to-ground and / or cruise missiles within the next 72 hours, and the possibility of intermittent disruption of radio navigation equipment, due consideration needs to be taken when planning flight operations in the Eastern Mediterranean / Nicosia FIR area.”

Around this time LCCC/Nicosia FIR released this vague (and now deleted) NOTAM:

A0454/18 – INFORMATION TO AIRSPACE USERS

THE DEPARTMENT OF CIVIL AVIATION OF THE REPUBLIC OF CYPRUS IS CONTINUOUSLY MONITORING THE GEOPOLITICAL DEVELOPMENTS IN THE REGION AND WILL NOTIFY THE AVIATION COMMUNITY IF AND WHEN ANY RELEVANT AN RELIABLE INFORMATION IS AVAILABLE THE DEPARTMENT OF CIVIL AVIATION IS TAKING ALL APPROPRIATE ACTION TO SAFEGUARD THE SAFETY OF FLIGHTS. 12 APR 15:25 2018 UNTIL 12 JUL 15:00 2018 ESTIMATED. CREATED: 12 APR 15:26 2018

Beyond this alert and NOTAM though; nothing else happened. A few days later, the conflict escalated.

Very few commercial flights operate over Syria, and authorities in the US, UK, France and Germany have all previously issued warnings for Syrian airspace.

But many airlines regularly transit the LCCC/Nicosia FIR: there are frequent holiday flights to the main Cypriot airports of LCLK/Larnaca and LCPH/Paphos; overflight traffic from Europe to the likes of OLBA/Beirut, OJAI/Amman and LLBG/Tel Aviv; as well as traffic from Istanbul heading south to the Gulf and beyond.

What has happened in the few weeks since then?

Normal Eurocontrol protocol is (during expected ATC strike for example) – regular teleconferences with operators, active re-routes and removal of certain overflight approval requirements. So did that happen this time? No.

Essentially just radio silence on Syria and operations in the Eastern Mediterranean Sea.

Right now, it’s a busy place. With all the normal holiday traffic in the region, there is also a large number of military surveillance aircraft from numerous nations patrolling the region. United States assets operating from Greece and Italy. UK air power from Cyprus and the French from bases in Jordan. Add to that the normal Israeli defense air frames and even the odd Swedish gulfstream surveillance flight!  Then there are the Russians conducting aerial operations and defense exercises in and around Syria.

Cyprus has activated a litany of “temporary reserved/segregated areas” inside of Nicosia FIR.

On May 3rd, Cyprus issued this vague information, to ‘exercise caution’.

A0580/18 – NAVIGATIONAL WARNING TO ALL CONCERNED. EXTENSIVE MILITARY OPERATIONS IN NICOSIA FIR PILOTS TO EXERCISE CAUTION AND MAINTAIN CONTINUOUS RADIO CONTACT WITH NICOSIA ACC. 03 MAY 12:00 2018 UNTIL 31 MAY 23:59 2018. CREATED: 03 MAY 11:25 2018

There is also a current warning about GPS interruptions.

A0356/18 – RECENTLY, GPS SIGNAL INTERRUPTIONS HAVE BEEN REPORTED BY THE PILOTS OF THE AIRCRAFT OPERATING WITHIN SOME PARTS OF NICOSIA FIR. AIRCRAFT OPERATORS OPERATING WITHIN NICOSIA FIR ARE ADVISED TO EXERCISE CAUTION. 20 MAR 10:04 2018 UNTIL PERM. CREATED: 20 MAR 10:05 2018

It may be unfair to blame the authorities completely. At the end of the day, due to the lack of appropriate communication from the various security agencies it’s hard to get accurate information out there. Still, there was enough warning to alert civilian operators of imminent strike – but then nothing else. Shouldn’t airspace customers and users expect more?

So what to make of all this?

Let’s end it with this great 2009 (and still current) NOTAM from the Cypriots.

A0687/09 – NAVIGATION WARNING TO ALL CONCERNED.

15 SEP 09:30 2009 UNTIL PERM. CREATED: 15 SEP 09:34 2009

 

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.

NOTAM INFO: NAV GPS (AFSMO GPS 18-04) (INCLUDING WAAS, GBAS, AND ADS-B) 
MAY NOT BE AVBL WI A 361NM RADIUS CENTERED AT 470259N1103758W (GTF115040) 
FL400-UNL,

222NM RADIUS AT 10000FT

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.
