"We are not convinced that NATS' systems are sufficiently robust to enable it to reduce the numbers of safety-critical staff. Air traffic control assistants are vital to the safe operation of air traffic control, and it is incredible that NATS intends to reduce their number so soon after moving into a new, highly complex operating environment. It is essential that NATS and the CAA clearly demonstrate a substantially greater level of robustness in computer equipment at Swanwick before embarking on the planned reductions"
A little refreshing given the recent bout of ATSA bashing that has taken place on this forum recently (on the subject of pay rises).
