- You need to fly to Paris CDG (LFPG), but let's see what happens with an error. Type EGLL/EDDF and press 1R. That's Frankfurt — the wrong airport!
- Enter your flight number BAW304. Type BAW304 and press 3L.
- Wait — EDDF is Frankfurt, not Paris! You need LFPG. Correct the route by typing EGLL/LFPG and pressing 1R again. The MCDU will overwrite the old FROM/TO.
- Good catch! Now set cost index to 35. Type 35 and press 5L.
- Set cruise flight level FL350. Type FL350 and press 6L.
- Navigate to F-PLN to verify your route shows EGLL and LFPG (not EDDF).
- Insert airway UL9 after EGLL. Type UL9 and press 1L to open the AIRWAYS page.
- On the AIRWAYS page, airway UL9 runs DVR → KONAN (see the VIA preview). Enter KONAN as the TO waypoint: type KONAN and press 1R.
- Now press 6R (INSERT*) to splice airway UL9 into the route — DVR and KONAN drop in after EGLL.
- Close the discontinuity: type LFPG into the scratchpad, then click the LSK next to the discontinuity to replace it with LFPG.
