    Even our dedicated international jets - 747-400, A330, 767, 777 - had limits to the regions the FMS was authorized to operate. I suspect that is due to the data base the company purchased. We didn't fly polar routes and didn't need the capability. I don't think there is any inherent limitation other than the data base for navigation by an IRS/GPS based nav system. Our total procedural requirement involved selecting true heading for our instruments at extreme northern latitudes. The machine even told us to do it. I'm amazed how things have changed every time I think back to the times I watched my harried nav dig through almanacs and scribble all over his charts. All to find out we were probably over North America - somewhere. Maybe.

      He said "Well, we're lost but we're making good time".

      If the pilot's good, see, I mean if he's reeeally sharp, he can barrel that baby in so low... oh you oughta see it sometime. It's a sight. A big plane like a '52... varrrooom! Its jet exhaust... frying chickens in the barnyard!

      •  navigator humor? (1+ / 0-)

        I think that most B52 navs DID have a sense of humor originally. But thousands of hours spent sweating in the BUF basement, with no lights, no windows, little career progression, next to the fragrant “toilet”, may have adversely affected more than our ears and eyesight.   I've seen lots of beautiful places.....on radar.  Still, it was an interesting time, spent with some highly skilled aviators. Any pilot who can refuel a BUF in bumpy wx coulda been a successful neurosurgeon, in my book. Keep your chapters coming, Major Kong, very enjoyable reading.
