Welcome to
Fly On Track Radar Replay #6
Stansted CTR

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 replay does give a written commentary of what is happening, but if you haven't seen one of these replays before, the commercials with squawks are departing and arriving the main runway at the end of the ILS line. The ILS is marked in 2 mile 'notches'. You can see the altitudes of the commercials through the 3 green digits beneath the squawk, which gives 'hundreds of feet' (so 020 is 2000'). The amber 3 digits if present gives the level the aircraft has been cleared to reach. Here's one of the learning point: At some stage, the departures will stop, then, later, restart. Try and think why this would be, and don't look at the answer until you have seen the replay and thought about it. The answer is on a link below, but don't spoil it, watch the replay first. 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! If you have watched the replay by clicking on the radar head on the left, and you would like to know more, and how departures continued, the answer is on a link here, but don't spoil it, watch the replay first. To understand why departures continued, finally click on: The Answer

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!)
