The latest edition of Chirp has a comment [P5 (2)] about rapid-fire ATC transmissions on the LAM sector and it starting to happen on the DTY sector, where no sooner has the (wrong) aircraft acknowledged the instruction than a new one is issued to another a/c, with around a half-second gap. The intended 'cleared' a/c is unable to get a word in to correct the error and it is suggested that the controller has not 'heard' the incorrect read-back. It reports of multiple attempts to contact as well due to R/T traffic load. I have experienced this R/T congestion myself on many occasions.
If you guys and girls are THAT stretched, what can WE do about it? Will MORs help? Obviously where a controller has not listened correctly to a read-back an MOR will NOT be a 'good thing' for that controller, so any other ideas? CHIRP has called for MORs, and suggests they should have been filed in the past. It sounds as if you need some help!!
