Update it. Not sure of your kit, but in ours we brief the Nav Accuracy status before ToD, and if that status changes at any stage, the box tells us, thus no need to check it (though obviously good airmanship dictates blah blah etc) Knowing displacement from extended c/line is useful for predicting turn for intercept. e.g. At 180 knots GS, and a 45 degree intercept, if we haven`t been cleared for the approach with 1 mile to c/l then might be worth giving ATC a nudge, much nicer for pax to int off a 45 degree hdg change, than shoot thru, and atttack from the other side. We are there to give a smooth safe ride after all. But one example.
How long is the other guy pushing buttons for? Surely not long enough to get that far out of the loop.
