What I don't understand is, if AgustaWestlands AW101 could carry up to 5 tons while the Chinese's AC313 could carry only 4 tons, how come AW101 can only take 20 troops while AC313 could carry 27 troops?
Actually according to wikipedia, the AW101 could have 25seated troops or 45 standing troops and not just 20 troops.
Reference:
That just means that the AW101 has a smaller interior space (or more spacious seating) than the AC313. Has no relationship with lifting power.
