Who comes up with these ideas? The madness seems to be spreading too. Everywhere we look the rules are weighted in favour of getting rid of flexibilty and delaying traffic - it really does delay traffic on a runway working near capacity. At the same time the traffic keeps coming. Something has to give. How are we supposed to move the traffic with our hands being tied ever further behind our backs?
Conditional clearance are safe if they are used properly. They have also saved my bacon on a number of occasions - where the situational awareness that they afford has mitigated against errors in reporting runway entry point. I can not remember any time that an appropriate conditional clearance has contributed to an incident.
I wish the nats department of silly ideas would stop meddling.
