"As soon as you're cleared for the approach it cancell any previous speed restriction, unless otherwise specified."
Reading this again: If I clear the aircraft for the approach and do not specify a speed with that instruction, the implication is that the aircraft can fly its own speed!
I believe that where positive speed control is being applied, the last assigned speed is the one that should be flown "unless otherwise specified", anywhere outside 4DME. If, as is being suggested here, aircraft believe they can adopt there own speeds when cleared for the approach, it may explain why we have so many non compliance issues with our expectations. Is that the way pilots actually interpret "cleared for the approach"? This does raise another issue (no wish to hijack the thread), when a speed instruction is issued, what do flight crew consider to be an acceptable response time to act upon the instruction?
