About IGS approach

[uttamsingh1638]

Is the ILS and IGS transmitter and receiver are same? how we install the ILS component in case of IGS approach? wat is the meaning of 47 degree offset....:sad:

The IGS at Kai Tak was indeed a conventional ILS localiser and glide path transmitter assembly however it was situated on a small rocky hill to the west of the airfield and not in line with the runway as is usual. Its purpose was to position the aircraft to a point over Kowloon from where a visual right turn through 47degrees was required to line up with runway13. Hence the statement in the AIP that `continued flight on the IGS did not ensure terrain clearance`!! When visual and by minima at latest, the IGS had to be disregarded, the GPWS G/S signal inhibited and the turn onto the runway flown by visual reference. For 80% of the year the cloudbase was above 1500ft with good visibility.
