On the point that has been raised at a users committee a couple of times, the chatter on Zone 120.6 can get wearing. I appreciate that you use it for training and so absolute correct procedure is being taught, but sometimes the repeated references to traffic in the ICARA's can defeat the purpose of Zone and Information.
If someone is trying to lift/deposit a dodgey load with his/her Lama off a pinnacle in a hooligan of a wind, the last thing they need is being required to answer to traffic information on a transit that is two miles and 1500 feet away. I know your are only following the ICAO procedures, but perhaps we should file a Hong Kong exception report and just handle Zone and Information as the controllers and pilots want it. ie see and be seen and use the mode C a bit more.
