Hi
yes, at a reduced weight, is possible to perform, but in most cases the fuel/payload relation will be downgraded
imagine a profile like this
5/6 POB, +2hrs fuel, IFR, helipads/confined areas, 8000ft DA
* what are the ones, that do it at MGW
and
* the ones that with this profile, and with "that" reduced weight can perform class 1
and tell me if you dn't think that well be needed to use "ovesized" helos, to comply with everything...
