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 ENTRY** - `SSOXS → Q167` — **works** - `RBV → 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. ---

Hi, Wow, what a report … The best thing I have ever seen. A great example of how to write reports. Perfect, much appreciated … very impressed. But back to the topic: I will check it, but I have also identified an issue with a waypoint on an airway. Possibly it is the same issue. Let me check it in more detail. I will come back to you with my results. Please give me a few hours. When needed, we will release a second revision (or course). Thanks again Richard ---

Thanks for the quick reply. Looking forward to hearing what you find. I have flown this same route out of Hong Kong many times in the 777, entering the route manually each time, and I have never had an “INVALID ENTRY” for any of these airways/waypoints. ---
