Can anyone post a copy of Amendment No. 5 to ICAO PANS-ATM 6.3.2.4 and 6.5.2.4, referenced in the link below?
http://www.hkatc.gov.hk/HK_AIP/aic/AIC18-07.pdf
Over the years, there have been many threads started on this issue, with diametrical positions. After spending hours reading these threads, it does seem that the general consensus is that in the U.K. and U.S., an amended altitude by ATC will cancel the subsequent altitude restrictions on a SID or STAR, unless they are restated. In Australia and New Zealand, they are only canceled if they say something to the effect, "cancel SID/STAR, track direct."
Based on the aforementioned link, it looks like Hong Kong follows the Australia/New Zealand position.
I am trying to compile information on other countries' positions, but I don't have access to each of the countries' AIP's (presuming they would even address or clarify the issue). For instance, how do they do it in South Korea, Japan, or the rest of Europe?
Of course, I realize that if there is some uncertainty it might be prudent to clarify with ATC that it is an unrestricted climb/descent, but that's a lot like asking the controller if you are cleared to cross all other enroute runways when he/she clears you to taxi to a runway in the U.S., without any qualifying hold short instructions--asking if you are cleared to cross the runways manifests an ignorance on the subject and would probably irritate a busy controller.
Any documents on the subject would be greatly appreciated.
Thanks in advance.
