After updating from AIRAC 2609 to AIRAC 2610, certain airways return INVALID ENTRY when manually entered in the PMDG 777 FMC.
This did not occur with AIRAC 2609.
Aircraft / Software
- Aircraft: PMDG 777
- Simulator: Microsoft Flight Simulator 2024
- Navigation data provider: Navigraph
- Previous AIRAC: 2609
- Current AIRAC: 2610
Steps to reproduce
On the PMDG 777 RTE page, enter:
VIA: DIRECT | TO: DALOL
Then on the next line:
VIA: V631
The FMC immediately returns INVALID ENTRY.
The individual waypoints are valid. For example, DALOL and ENVAR are both accepted, and DALOL → ENVAR can be entered as DIRECT.
The same behavior occurs with:
MADOG → Y753— INVALID ENTRY
Additional airway testing
To determine whether the problem affected airway entry generally, I tested additional airway segments on separate flights using AIRAC 2610:
BURGG → Q22 → RBV— entering Q22 returns INVALID ENTRYSSOXS → Q167— worksRBV → Q419— works
SimBrief comparison
The complete VHHH → KLAX route:
DALOL V631 ENVAR M750 MADOG Y753 JAKAL A1 ALBAT Y755 CARDS HIOTI CBE MORIZ TENRU Y88 DAIGO Y889 OATIS OTR3 PUTER A590 PUGAL A590 POWAL 5100N/17000E 5200N/18000W 5200N/17000W 5200N/16000W 4900N/15000W 4600N/14000W 4200N/13000W VESPA AMAKR BOARS SNS J126 RZS
loads correctly when imported from SimBrief.
Therefore, the route and individual waypoints are available in the database, while the manual airway lookup rejects certain airway segments.
Also, I had this issue in both the 777-200LR and the -300ER.
