A total of five aircraft came into conflict at high flight level (FL350 and FL360) over Madrid in a very complex traffic scenario leading to a series of compromised separations and a TCAS RA.

A Ryanair UK Boeing 737-800 (red colour in map below), registration G-RUKB performing flight RK-1365 from Rabat (Morocco) to London Stansted,EN (UK), was enroute northbound at FL360 about 30nm west of Madrid.

A Nouvelair Airbus A320-200 (yellow colour in map below), registration TS-INO performing flight BJ-6131 from Porto (Portugal) to Djerba (Tunisia), was enroute at FL360 eastbound about 40nm west of Madrid when the controller initially wanted to turn the A320 right, upon query by the crew left or right the controller turned the A320 about 40 degrees to the north (left) recognizing the separation with the Rynair UK B738 would be compromised. At the same time the B738 G-RUKB was instructed to descend to FL350 and turn 40 degrees to the right.

A British Airways Airbus A320-200 (purple colour in map below), registration G-EUUE performing flight BA-493 from Malaga,SP (Spain) to London Heathrow,EN (UK), was enroute at FL360 northbound about 20nm south of Madrid.

As result of the recovery of the compromised first separation a conflict now arose between the BA A320 and the Nouvelair A320. The BA temporarily climbed to FL370 and after being clear of conflict descended back to FL360.

A Ryanair Boeing 737-800 (green colour in map below), registration EI-ENA performing flight FR-656 from Malaga,SP (Spain) to Glasgow Prestwick,SC (UK), was enroute at FL360 northbound about 40nm south of Madrid.

A Vueling Airbus A320-200 (blue colour in map below), registration EC-JTR performing flight VY-8829 from Paris Charles de Gaulle (France) to Sevilla,SP (Spain), was enroute southwest bound at FL350 about 70nm northeast of Madrid.

Also as result of the recovery of the compromised first separation the Nouvelair A320 also came into conflict with the Ryanair B738 EI-ENA. The A320 was now instructed to turn 90 degrees right and EI-ENA to turn 40 degrees to the right which however did not resolve the conflict. A TCAS Resolution Advisory prompted EI-ENA to descend from FL360, which however caused an additional conflict between EI-ENA and the Vueling A320 at FL350. EI-ENA stopped the descent at FL357 and passed underneath the Nouvelair A320 with 400 feet vertical separation and about 5nm horizontal separation. EI-ENA subsequently climbed back to FL360 to become clear of conflict with the Vueling A320, which in the meantime had been turned 40 degrees to their right, too.

Once the Ryanair UK B738 G-RUKB was also clear of the Ryanair B738 EI-ENA the aircraft was turned back left northbound and climbed back to FL360.

Finally all aircraft were on diverging trajectories, the Ryanair UK B738, the Ryanair B738 and the BA A320 at FL360 northbound north of Madrid in close proximity however with sufficient separation, the Nouvelair A320 at FL360 eastbound east of Madrid and Vueling at FL350 south of Madrid southwest bound.

All 5 aircraft continued to their destinations and landed there without further incidents.

A Listener on frequency alerted the AVH to the occurrence and also reported that the controller's desk had issued alerts even before this sequence of events unfolded.
