Kaptain M, yes an a/c needs flt crew to fly that is given. However for him/her to be able to legally fly that a/c that a/c has to be released for flt and under the HKGCAD Law an appropriately approved/licenced/authorised engineer has to sign the CRS for any or nil defects the a/c may have, the maint check that is c/o iaw the Approved Maintenance Schedule (even a transit). As for the freighters, even though they do not have Cabin Crew, still require that release, that is the Law in HKG (and elsewhere), so whilst you're sat there waiting to go, until I sign it off you ain't going nowhere.
