Why does SQ sometimes use 06R for dep at MAN

[speed freek]

Hi mate,

never seen the 777s go off 06R, however their 747s do it all the time. Apparently, I've been told, the hump on 06L makes them performance limited or something like that. Then again, looking at PIA 747's roll off 06L, SQ may be onto something - only a matter of time before those houses have their roofs blown off again!!!

Cheers,

Speedy
