Sorry, I should have added that the Mk1 Service Deviation had no equivalent in Mk2, therefore the installation must either have been cover mod'd or, if it remained exactly the same, the RAF didn't get round to issuing a new SD. Neither GPS or TANS is mentioned in the list of Mk2 mods.
Of course, if one were to believe Adam Ingram, the above is academic as the Mk2s were new build, so could not have inherited any legacy configuration control problems from the Mk1. But, he lied and we don't believe him.
CDP (Walmsley) admitted this to the HCDC in 1999 when acknowledging the Chinook suffered from configuration problems. And AD/HP1 said it had significant systems integration problems. All this adds up to an immature and unmaintained build standard which, in turn, largely invalidates any safety case; meaning the decision to sign both the CAR and RTS was deeply, some would say criminally, flawed. Both documents are fabrications as they deliberately misrepresent the facts. This is beyond gross negligence.
