Thats another nice airport you have there!! haha... So you are in the 747? So its you who did not clear with Ground huh??
Anyway one more question, for ILS approach, when on A/P, I reliease that ALT will be take over automatically right?
When will it take over precisely? i don't know, cuz some time it takes over, sometimes it does not.
I tried many times, I kinda figure out that once the GS is center it should take over, am I right? Hmmmmm.... but then again sometimes even when it takes over when its center with the GS, it will still go outta GS and dive right down.

Man...so many confusion here...
hehe
