MRH90 External Load Lift capability
This aircraft was procured with a good external load capability (we thought) - up to 4000Kg on a very smart hook that would measure the load and use this weight to recalculate your performance. Like most helicopters, it is actually incapable of lifting this ultimate weight. All Up Mass - Basic Mass is less than 4000 ! Anyway, as it turns out the hook is a bit too smart - the articulations in roll and pitch (via axles / beams) mean that no only is the hook incompatible with the RAN standard load lifting equipment, it is also moving too much for the airframe strength. Back to the drawing board NHI !
