Quote: "I'd have thought that a runway going through the T4 site would be too close to 09R/27L to allow sufficient separation for independent operations."
So what is the exact minimum physical separation required for 2 parallel rwys for simultaneous operations? At Heathrow the 2 existing rwys are a little under 1 mi. apart, is this a lot more than required?
But these rwys pre-date any civil aviation regulations, the modern airport started as RAF Heathrow, and was built to military requirements. It is pure co-incidence that there was space for mid-field terminals.
