Hello,
Navigraph Charts displays an additional large, almost complete loop near EGGW when selecting the MATCH 3Y departure from Runway 25.
Test details:
- Airport: EGGW London Luton
- Runway: 25
- Procedure: MATCH 3Y, abbreviated MATC3Y in the navigation database/FMC
- AIRAC cycle: 2608
- Validity: 06 August 2026 – 03 September 2026
- Data provider: Navigraph/Jeppesen
According to the current UK AIP, the procedure should be:
- Climb straight ahead on 253° to 1030 ft QNH.
- Turn left direct GWS01.
- Continue to GWS06 on track 211°.
- Turn left to GWS12 on track 090°.
- Turn right to GWE16 on track 102°.
There is no holding pattern, orbit or near-360° turn between the runway and GWS01.
The aircraft FMC displays the correct route topology, and LNAV also flies the departure correctly. The problem therefore appears to be limited to the Navigraph Charts procedure overlay. The waypoint sequence shown by Navigraph is correct, but the additional large loop near the airport is not part of the published SID.

Could you please check the rendering of the CA 253° → DF GWS01 transition for this procedure?
Thank you.
