A Qatar Airways Boeing 777-300, registration A7-BAO performing flight QR-778 from Miami,FL (USA) to Doha (Qatar), was enroute at FL350 about 15nm northeast of Zurich (Switzerland) when the crew reported smoke on the flight deck and requested to divert to Zurich with CATIII ILS available for runway 16. ATC reported that only CAT I was available right at that point, CAT II was being activated. About 10 minutes later ATC reported that CAT III was now available for runway 16. The crew requested to dump fuel, but subsequently indicated they were not dumping and preparing for an overweight landing as they had problems with the fuel dump system, then the crew indicated they were now dumping fuel. The aircraft established on the localizer runway 16 still dumping fuel, reported they needed more track miles to descend, were vectored off the localizer again, finished dumping and rejoined the localizer. Tower queried "Confirm gear down and locked", response "gear down and locked, thank you", the aircraft landed safely, the crew indicated they would stop on the runway and requested emergency services to check whether there was any smoke visible. Emergency services reported no smoke. The crew reported everything was now normal again, the crew cancelled Mayday and decided to vacate the runway and taxi to the apron.
