ShyTorque But these 2 aircraft are in the same wake turbulence category and so require no wake turbulence spacing between them. I don't think that this is done for smaller helicopters (but accept that it's mission dependant rather than size).
I’m surprised to hear they are in the same category. A Blackhawk weighs 10 tons and a C-130 weighs up to seven times as much. Yet I have heard that an AW139 (approx. 6.5 tonnes) will now require wake turbulence separation from helicopters such as a 109, max weight 3.175 tonnes.
