Out Of Date SIGMETS and AIRMETs

Charts General
1

I have noticed many times that the SIGMETs and AIRMETs that are displayed on Navigraph charts are always or most of the time expired. When comparing information found on SkyVector, there always seem to be some missing or expired ones that are still being shown. Even when using simbreif, I get current, and up to date sigmets, but often they are not shown on Navigraph Charts. I have linked some photos for comparison from a flight I was doing from RPLL → VHHH. SkyVector always has up-to-date SIGMET overlays.

Notice the difference between the two. Navigraph is also missing tropical storm SIGMET.

Hello! Thanks for the feedback.

We currently deliver all SIGMETs and AIRMETs available directly from NOAA/AviationWeather, including expired ones that have not yet been removed. We shall investigate any delay and consider hiding the expired reports!

Thanks again for the report!

Kind Regards,
Malte
