My point wasn't a criticism of anyone, esp ATC.
My usage of ATCOs is mostly under a FIS - that means that they pass me information if they have it. Note that they do not have it all. Neither do I.
On an airfield I would assume that I will follow commands as they are likely to have a better view than me.
There have been situations in the air where ATCOs have given instructions to me which I am unable to comply with. I am driving the thing, and if I screw up the CAA will hit me, not them.
There are situations, such as when someone on the ground shouts 'Stop', or when an ATCO says 'go around', you will follow the instruction - you are daft if you don't.
However, if they say 'nothing known to conflict......' that doesn't mean there is nothing about.
My point is purely that accidents and misunderstandings will happen regardless of ATC or technology. We've just got to try to minimise the possibilities.
