Pilots : Regarding VHHH J9 & J1 TO
Should Ground Control clear you to J9 (25L) or J1 (07R) for departure and should you really want the extra 99m that J10 or H1 affords, I request that you make said call to Ground and not to Tower as this decision falls within Ground's jurisdiction. I'm sorry to burden flight crew with this but maybe you will be able to get through to those who don't seem to understand the difference.
Any counter-argument supporting taxi to J9 or J1 is academic as flight crew who see the full length available will invariably ask for it and further, should Ground Control specifically require J9 or J1, then Ground can explain their reasons directly.
