At least they managed to reach Canada before returning home. It looks like a medical emergency.

This Friday morning, when 66,000 passengers were expected to go through Brussels Airport, technical problems at Belgocontrol delayed operations and traffic was at 70% of normal. At 0900 local time, all problems were solved and departures could resume normally.

From what I understood in the Eurocontrol jargon, the problem was due to data exchange with foreign air traffic management centres. Belgocontrol was stuck on the 2 sector night configuration, and at 0900 Brussels had 4 sectors open and the situation was recovering.

Not really an abnormality as such, but something I noticed overhead Belgium on FR24 today. Two aircraft with different Mode-S transponder codes, though they were transmitting the same aircraft registration. Spotted overhead Diest. Apparently, one of the two departed in MST, the other one seems to have taken off in Diest.

Interesting catch KriVa.

It is not the first time that such thing happen, usually after a swap of transponder, but here ....?

The third screen shot shows a legit reg.
OO-FFB.png
OO-FFB.png (30.59 KiB) Viewed 8528 times
This ICAO 24-bit code is well attributed to OO-FFB, the one and only. This aircraft belongs to Para Centrum Vlaanderen, Schaffen, Moorsele, Zwartberg.
Its ICAO 24-bit code "4498C2" shows she is registered in Belgium (codes between 448000 and 44FFFF in Hexadecimal).

So the "other" is not OO-FFB.
Moreover its transponder shows an ICAO code (DDDAFE7) that is not supposed to be allocated yet !
If my Annex 10 is current, the addresses starting with 1011, 1101 and 1111 are reserved for future uses.
Converting DDAFE7 in decimal gives 1101 .....

So you have spotted an aircraft that FR24 gives as having a wrong Reg and a non allocated ICAO 24-bit address.
:wtf:

Go figure.

In fact, it is one and the same airplane you see. This is a common occurrence around mixed traffic parachuting/glider airfields. The tracking info is fed to FR24 by two completely different technologies, which do not correlate correctly. On the third screenshot you see the standard Mode-S ADS-B based info (with transponder code) and the second is the FLARM (glider anti-collision system) based tracking (no squawk). In summertime you see a lot of glider traffic through FLARMs feeding FR24. Some para-planes, like in this case, also carry FLARM, to help de-conflicting with gliders, next to Mode-S ADS-B found more commonly in (larger) powered planes. And every now and then, you'll see a 'top-of-the-bill' glider also carrying both.

Thank you DIBO for that clear explanation.

This FLARM is indeed very useful as I remember the crowded place when I was flying down south of France. Although my understanding is that it will not trigger a TCAS alarm with an aircraft. That would have been very nice to have and avoid the close shave we had with an A320. :cry:

It is probably because this FLARM is portable like a hand-held GPS that the 24-bit code is not "country-allocated" then?

didn't know it either, but found this explanation, so Flarm users sometimes use their device-ID which starts with a hex D (so totally not linked with ICAO logic)

Surinam Airways brand new (second hand) A340-300 PZ-TCR was supposed to be delivered at Amsterdam today as flight PY-3002.

However, the flight went into a holding west of Rotterdam, and then diverted to Brussels.

FR24 shows that SN501 BRU-JFK is on his way back to BRU, heading to SNN right now. Strange.

It seems to me like that would be a 'glitch' in FR24, since they don't have reliable/any coverage over that part of the ocean. (Hence the dashed track). If it actually comes back to BRU/SNN, it should be visible by radar by now, and not only by the FAA data (which is what the orange aircraft symbol hints towards. Yellow = live data, orange = FAA data with a minor delay).

JAF-6833 737-800 OO-JAY Brussels-La Palma diverted to Tenerife yesterday evening (deviated at the first landing attempt at SPC). OO-JAY flew back to La Palma about two hours later, but the next JAF-6834 La Palma-Funchal-Brussels was delayed from Saturday evening till this morning.

Final delay for arrival JAF-6833 in Brussels: 00h55 becomes 16h30.

This looks like a weather-related delay, compounded by a limit on duty hours of the crew. I'm afraid that the passengers will not get any compensation. Knowing JAF from a previous similar personal experience, they certainly have provided free accommodation and meals to the delayed passengers.

SN3603 to MRS seems to be returning to BRU on FR24.

The same aircraft (RJ100 OO-DWB) took off again after return, and meanwhile has just landed in Marseille, so return was probably medical.

I don't know if the "too much beer" in the following story was caused by the above delay, but anyway:

A 30-year old male French passenger has been sentenced to 12 months in prison for trying to steal the automatic gun (an Uzi?) from a soldier at Brussels Airport. The passenger was enjoying a few beers ahead of his flight back home to Albi, when he tried to steal the gun from a para on duty. Other para's immediately intervened and subdued the man.

The man was interrogated by the police that day, and declared he was drunk and had no idea why he did it. He then was released the same day. Today apparently was his court day. And because he didn't show up, he gets 12 months non-suspended.

My guess: if he would have appeared in court, he would probably have had the same sentence, but with probation.

Most units deployed carry the good ol' FNC. Otherwise it could have been an FN P90 but not that many units are equipped yet.
Their pistol if the FN Five-seven.

In any case, don't mess around.

Final report about an incident at Barcelona, Apr 28th 2015:

An Air France A321-200, registration F-GTAZ performing flight AF-1449 from Barcelona to Paris Charles de Gaulle was taxiing to the assigned departure runway 25L and received clearance to cross runway 02. The aircraft reached the hold short line of runway 02, noticed the stop bar lights were illuminated, stopped the aircraft before the hold short line and radioed ground control to verify whether they were indeed cleared to cross runway 02. At this point ground control instructed the aircraft to hold position.

A TNT Airways B737-400 freighter, registration OE-IAP performing freight flight 3V-421J from Liege to Barcelona, was on final approach to Barcelona's runway 02 and had been cleared to land on runway 02 about one minute prior to the Air France crew stopping their aircraft at the hold short line.
