Rananim/Shaka Zulu,
I concur. 210 to 6 on ATC's request into 24L @ PMI was more of a struggle.
You can pull the gear at 270 on the 733/4/5 and the speedbrake can be left out to F10 - our SOP.
To be at 1800AGL on the GS & 210/6 from 300/10 you need to lose 90kts in ~1min = 1.5kts/sec. Quite possible with a level segment + speedbrake =~ -1kts/sec from 300 - 270, followed by gear down + speedbrake =~ -2kts/sec from 270-210. Then start down the slope...
Bit noisy though.
All within limitations.
Just like my CAP371 roster.
Next time ATC ask you for "210 to 6", the detractors now have a choice to make...rather than spit out their dummy! Make sure there isn't a tailwind.
