Hey, can't anybody answer fkelly's question of operational weight?
Manufacturer's empty weight claims are always have an air of unreality about them. 139 Gross is 6400 kilo, empty SAR version is probably around 4300KG, add in two pilots, winchman, swimmer, you gotta be at 4700 kg. Fuel burn is 450kg per hour. Load up with 3 hours of fuel and you've got a mission range with reserves of about 150nm. Seems to me the useful load is only 400kg, not Mr. Optimistic's 2778kg.
Anybody care to provide better numbers based on operational experience and not a factory brochure?
