Route Offset
Given the accuracy of GPS equipped a/c, why isn't a random offset built into into the system for en-route operation when flying in RVSM and other airspace?
I did hear that in Africa, pilots will rte offset using the FMC "just in case".
Visiting the cockpit once of a 744, I could clearly see on the EFIS display that the commander was flying an offset, but didn't ask him why.
Wouldn't a random minor offset built in, and non-adjustable by the pilot help minimise mid airs?
I was just thinking about the 757 and Tu-154 collision, and possible ways it could have been avoided.
