Tired, Thanks very much for giving me some answers and insight into the 25R overshoot. I apologise for the confusion on which runway I was talking about, yes you’re correct 25R was what I was trying to resolve. Again thanks Tired.
I’m sorry OzExpat if you feel I have an ulterior motive by trying to squeeze out of any pilot, some very expensive research information that their company has done in this area then please believe me, that is certainly not the case. If any other airline were ti use data from another airline without their permission were found out, then there would be serious court action for compensation. No not at all.
What I’m trying to do is both self preservation AND until my airline can be convinced that they must look into this and use one of the many international firms that specialise in airfield performance analysis and to produce their own approved missed approach.
Tired, forgive me if this sounds stupid, however, until I go back to work to look at the 25R chart, if the MAP is say approx 1 mil prior to 25R threshold and the right turn on 2 engines is commenced at 3 miles then isn’t total track miles 4 miles.
I couldn’t agree more with you that @ the 3 miles point on 2 engines AND you’ve commenced the right turn towards that very high ground, you should be “fairly” comfortable with obstacle clearance. At max landing weight or the 2nd segment/obstacle limit weight and doing this missed approach once you are committed to the right turn with some “fairly” decent height, the aircraft must perform all the way up to 5,000 OCA as published, do you feel that still a fair way to go.
And the other major concern I have to the designers of this published approach is the above situation engine fails as the right turn happens @ 3DME (you have some good height so far as you’ve been on 2 engines at your referred max limit weight and when you do the last step of this missed approach that is, you turn right on a heading of 100, you sail very very very close to the “JAL DC10” hill with the radar on top of it, with a stiff Northerly and you’re “making good” your 2.1% gross climb as per the certification of the 737/320s, not 7% ala chart, do you think you will come home for tea?
I’m glad the others agree that this issue whether its HKG or anywhere else in the world, does seem like its head in the sand stuff!
To John-tulla, Reynolds and OZ, once again many thanks for some good stuff discussion, answers on this important issue.
