While flying the 747-400 our MAUW was changed from 398 tones to 405 tones. I
asked
the Technical skipper what we had to do to qualify for that increase, difference
tyres, undercarriage oleos, tweak up the engine power etc. Answer: NOTHING,
except pay Boeing $1,000,000 per aircraft to be certified!
So be it.

graphs were altered to show things like increased take-off distance and reject
area requirements and of course reduced single engine climb rates.
