FMC - default 737

Question

Open FMS set valid ICAO codes for origin and destination, attempt to load a route via co route.(taken from Simbrief). Route loads successfully (by looking at the legs page  but Origin and Destination have gone from route page.

Have ran update and it detected no changed files, how do i fix?

Answer 1

You may want to just input the origin and destination airports back in. It did this to me as well following the update, though there were no changed files. Review the FMC plan and make sure the flight plan is accurate, otherwise this would result in a faulty and inaccurate plan.
