Thank you, PPRuNe Radar (from a sometimes confused pilot) for the clarification. That said, there are still (IMHO) too many occasions that ambiguity allows scope for confusion, and more importantly, mistakes and loss of separation, especially if operating into an unusual airfield (or if English is not the prime language). At the risk of increasing the RTF workload, perhaps we need something to ensure that crews are advised of any significant revision to clearance - I like the post from Check Wheels "Cancel STAR...." Anything for an easy life for both ATC and us pilots!!
