I’m currently sat on board a BA E190 at LIRF/FCO, which we boarded 45 mins late and have now been told by the captain that we have another 1h10 to wait before we can go. Apparently there is low visibility at EGLC, and the inbound flow has been restricted to 6 aircraft per hour.
I was wondering if any of the resident ATC experts could explain why such enormous separations are needed, even in low visibility conditions? From experience aircraft inbound on 09 are off the runway within a minute of touchdown, so while the back-taxi requirement and the fact it is a single-runway airport obviously reduces the flow rate compared to larger fields, one landing every 10 minutes seems excessively separated. What else is in play to require such gaps?
Any ideas or insights?
