There is no minimum, but Royal protocols were always to use existing class A wherever possible, and their travel budgets are closely monitored, so I wouldn't be too worried.
I once turned up at Dundee from Cranfield, to be told by Leuchars ATC just before handover to Dundee that a NOTAM had just activated for a SAR operation around the Tay bridge, as somebody had just been seen to have jumped off, and the coastguard helicopter had been launched. I imagine that the interval between the problem and the NOTAM was in single figure minutes, and quite rightly so.
I've actually often used that as an example in meetings to explain problems of co-ordination of manned and unmanned aircraft. I got neatly into Dundee by listening out, ascertaining the helicopter's search pattern, and co-ordinating a safe, but very steep (throttle closed, full flaps and sidesliping) and non-standard approach to land onto 27. My standard question to anybody advocating automated UTM, is how their system would have managed that situation?
I am Spartacus, and so is my co-pilot.
