if one day you have a nav data out of date problem on the fmc, and cannot be updated ,cause it isn`t in the company base ,no data disk out there.
the aircraft still can be released by the mel.
and during flight in the rvsm airspace, the atc request the crew to excute the offset to the right 5 miles, myquestion is: can the crew comply with the atc`s instructions?
can someone shed some light on me ? very appreciated!
