northernboyo, things have moved on to wider issues of access to Class D airspace. There are dark rumours (that is to say, I have heard but have no evidence) that access to Solent is being limited, or is going to be limited by controller capacity. That is exactly the issue I had at City, so it is entirely relevant.
Squawk 7500, so long as there is a prioritisation of traffic, the cargo is relevant.
Someone at DAP/SARG and someone at NATS have sat down and decided a hierarchy of priority, with ambulances and presidents near the top and NSF and pleasure flights right at the bottom.
They may feel that that is entirely justified, but in that decision do they have all the information? Yes, someone may die if the ambulance doesn't get through, but reducing funding to a homeless charity has consequences too.
So I say that it is also entirely relevant.
