If the 'tablet based system' referred to is the same one as introduced to the SAR Force, it was a moving map but it couldn't be installed on the aircraft due to the need for lengthy and expensive trials and modifications.
So it was a 'carry on device' that was worn on a kneepad - because it was 'carry on' it couldn't be integrated with the aircraft intercom to provide audio warning of wires, just visual - so much for reduced 'heads-in' what a fecking waste of time and money.
The database was good showing many domestic wires of the sort they hit but a proper, aircraft integrated moving map with audio warnings is what is required.
I cannot believe they have managed to wriggle out of producing a WSPS wire strike prevention system (cutters) for the Chinook, how long has it been in service??????
