U.K. NATS Systems Failure

[IFPS man]

Re Murty’s post #80
IFPS had, until recently, two Flight Plan Processing Units - IFPU1 at Haaren (Brussels) and IFPU2 at Bretigny (Paris). Each unit was responsible
for half of Europe. We at Bretigny were the responsible Unit for aircraft departing from Azores in the west, through Portugal, Spain, France, Italy, Greece, Turkey and the Med, along with airfields around the Med, for traffic entering European airspace.

We were not a back-up Unit for Brussels, rather a stand-alone Unit. Each Unit, however, backed up the other in case of a failure at either of the two Units. In fact, there were more “outages” at IFPU1 in Brussels than at Bretigny…
In 2006/7, the designators of the Units was changed to FP1 & FP2. During 2020, FP2 was closed down and the total airspace commitment transferred to FP1
