Welcome to
Fly On Track Radar Replay #5
Compton VOR

You can view a real radar replay of an infringement here if you have Windows Media player.... but before you do, read the following to understand what you are seeing....in this case, the infringing aircraft, squawking 7000, is already infringing at FL091 heading towards Compton VOR. (The 3 digits beneath the squawk - the NMS means 'no mode S' - give the flight level). As the clip progresses, you'll see controlled airspace is down to FL085 here. Then the controller gets an early conflict warning - the dotted white line - indicating a problem against a Luton departure routing to the VOR squawking '0355' at FL090 - so it is never allowed near. Later, as the clip progresses there is further avoidance workload for pilots and controllers - watch the 3256 squawk at FL080 which is vectored and kept level and as it passes the infringer, the latter starts a descent. It's well annotated, no need to say much more, look and learn!

Click on the image on the left to launch the radar clip. It is currently only available in 'wmv' format, therefore Windows Media Player should be used. Many thanks to all at NATS who have gone out of their way to make the public viewing of this clip possible. A different infringement and analysis will appear every few weeks - until they stop!

The latest radar replay (#7) shows an aircraft starting in the Manchester Low Level Corridor then infringing the CTR with the controllers breaking off approaches ahead of it.

The latest radar replay (#6) shows a small aircraft slowly transiting Stansted CTR.

Radar replay (#5) shows an aircraft not noticing the lowered airspace ahead near Compton VOR and breaking in at altitude.

Radar replay (#4) shows a student lost and crossing the Luton CTR and extended runway centre line.

This radar replay (#3) shows disruption caused by a short infringement into a layer of the LTMA over Sussex, eventually descending to the correct altitude but not early enough.

This radar replay (#2) shows a problem caused by a pilot NOT squawking Mode C and then getting lost eventually turning up close to the extended centreline of Stansted in the CTA. Due to the lack of Mode C the controller didn't know he was in the CTA.

The original radar replay (#1) shows the disruption caused when a pilot makes a navigation mistake and enters the Heathrow CTR and heads down towards final approach without realising it (at first!)
