Now I have got the weather minima sorted ( I have printed out Trolls post and stuck it inside my baseball cap) can someone tell me what all this new fangled helideck movement limits are all about? It used to be that as long as the r/o didn't say a number bigger than 3 degrees or 5 metres then everything was fine. Now we have heave rate, inclination, periodicity (which I always thought was something to do with menstruation) and recently someone told me that the limits change depending on whether the helideck is painted green or red. I have seen green ones, grey ones, dirty ones but never a red one. I am verily confused.
