Re: UK Coastguard SAR - Bristow out??
Assuming that the 225/92 de-icing equipment and aircon weigh the same, then based on the figures provided by HC, steve-oc and IF92s, my calculations show that the full-fuel payload of the EC225 would be 3845lbs and that of the S92 would be 3580lbs.
My colleagues tell me that at 4000ft ISA, at 145kts TAS, the fuel consumption of the 225 is about 1350lbs/hour.
Them apples are not looking too bad at all!
