747-400 FMC CDU "ROUTE FULL" Message
Gents, I was just wondering how you (and the FMC) would respond if the ROUTE FULL message appeared in the MCDU scratchpad?
If a route is uploaded (or selected from the Co Route list) and it exceeds the 120 waypoint limit, the ROUTE FULL message appears. Our airline used to have a few such routes from Asia to Europe a few years ago, but I don't know how they were handled. During ground tests, I seem to recall that most of the Route was accepted, with the final waypoints missing.
Q1. Will the full Route structure appear on the ROUTE pages? (even though not all the LEGS waypoints will be presented)
Q2. Will it be possible to enter the same Company Route in Route 2 and delete Airways and/or delete waypoints at the start of the Route on the ROUTE or LEGS pages and have the missing waypoints at the end of the Route automatically appear on the LEGS pages? (Then allowing you to switch to Route 2 at a convenient time)
Q2a. If the missing waypoints at the end of the Route do not appear, will the route end have to be programmed manually, waypoint by waypoint/airway by airway (using the paper flight plan)?
Q3. If a SID is added to a Co Route, causing the 120 waypoint limit to be exceeded, will the SID be accepted and the end waypoints dumped? If a STAR is added, causing the 120 waypoint limit to be exceeded, will the STAR be rejected or will waypoints at the beginning of the route be dumped?
Thanks for any insight
