I know that other planes such as the 747 had INS; so in a way this question is not specifically related to Concorde. With the radio navigation update was the lat and long of appropiate radio beacons hard wired into the system and then based on the assumed position the nearest beacons would automatically be tuned or did the pilots enter the lat and long of the beacons that they would then manually tune?
I guess there were three INS units to allow for drift etc and it would be easier to spot if one unit was less accurate than the other two. So when radio updating was not possible ie over the atlantic was it possible for the automatics to weigh against one rouge reading
Finally as Concordes ground speed was over double that of other aeroplanes was there any need to take this into account when designing and building the INS system(other than the speed display that would have to show an extra digit)?
Thanks
