Airline pilots have given Hong Kong their worst rating - a 'black star' - for shortfalls at Kai Tak airport in their latest internal report. The hair-raising approach that forces planes to bank sharply to the right just before landing is not the reason for pilot anxiety; what most concerns them is the distance between the runway and the parallel taxiway, which is less than recommended by international safety guidelines. The report is compiled annually by the International Federation of Airline Pilots' Associations and is intended for members' eyes only. John Findlay, general secretary of the Hong Kong Aircrew Officers' Association, which is member of the federation, said the black star did not mean Kai Tak was unsafe. 'So far as Hong Kong is concerned, the deficiency [in the distance between the runway and taxiway] . . . is overcome by the stringent application of segregation procedures which ensure there is no simultaneous use of runway and taxiway during adverse weather. 'We are totally satisfied that the procedures, which are enforced by the Hong Kong Civil Aviation Department, ensure a safe operation.' The distance between the centre lines of the taxiway and runway at Kai Tak is 111 metres. The international recommendation of 120 metres is deemed the minimum desirable margin between planes. Mr Findlay said if pilots equated the 'black star' rating with lack of safety and considered Kai Tak unsafe they would not fly there.
