.... I suggest not. If the landing turns out to be an 'eventful' one, someone's gonna want data for that.

...issue you raise really surprises me: the small amount of flight time for which recordings are kept. Some other posts have mentioned half-an-hour loop! Does anyone know what volume of data this entails? I don't know the volume... CVR and FDR have different amounts of data in terms of time. 1/2 CVRs are old. New ones can record hours. btw - for older aircraft, the biggest...

...When we dont use GPS, we use radio update of another type, usually. VOR DME. Without it, even the best INS can drift appreciably over time. It's not uncommon to see an error of a couple of miles after a long flight, and errors of 20 miles are possible after an ocean crossing. Radio update pretty much eliminates this and I've never seen any map shift whatsoever on a GPS updated system.
