Our ATM and not a DFTI is an exact replica of the Approach Radar, we can only use it as MTS Pt1 & Pt2 say so. However, in the real ATC world it is never used so. If you saw two a/c on collission course for each other would you only give traffic information, I would't. If they hit each other and you had only given traffic infornation then you would be heavily criticised and investigated. If you (with a valid APR rating) gave vectors to avoid and had an airmiss, again your b##ll###s are on the line. No win situation, unfortunately the UK ATC system has no protection for the controller. If you play it by the book and have an incident you will be in trouble for not using the saying in MATS Pt1 about any guidelines in this book does not mean that an ATCO can use his/her common sense. If you use your common sense and have an incident then you will be in trouble for not conforming to the MATS Pt1 or Pt2.
