It’s not the maximum rate of descent per se, it’s more about the horrendous noise the gear extended makes from 10,000’ and below at 250kts and the likelihood of the aircraft altitude catching up with the cabin pressure altitude at (say) 5,000’, after which the cabin pressure changes at the same rate of descent as the aircraft..possibly 6000’ per minute! The eardrums don’t take kindly to descent pressure increases above about 500’ per minute.

Reason: Spelling, typical pilot!
