twistedenginestarter - there is no such thing on PPRuNe as democracy. You think Danny wants or needs your approval for anything he does? There is no such thing as free speech here. Moderators need no invitation from you or anyone else to get involved in any thread. They have been appointed by Danny to keep the boards running by and large the way Danny likes. And the way he likes has turned this board from a very small site into just about the biggest aviation forum on the whole of the internet.
You don't like it? Tough. Go somewhere else.
411A - It's well past time that you wound your neck in. If you want to rely on GPS when the US Government next decides to degrade the system performance for its own purposes, then be my guest. GPS has also been demonstrated to be subject to interference, which INS is not.
The original question was how Concorde navigates and why they don't replace the INS system by GPS, not whether you think it is a nice aircraft or not, nor whether you think that anything and everything American is better than anything and everything European.
