St. John's International Airport problem report #28018 (open)

Two thoughts:

1. Your aggressive opening statement is factually incorrect. Airports in northern domestic airspace have runways numbered and weather reported in degrees true.

2. As @Bill35 noted, the true headings of runways are much more reasonable to record as permanent information in a database, as magnetic headings will change and can be calculated with a current map of magnetic variation (but the runways themselves rarely move). If the developer of a weather app chose to use an open database and not read the documentation on the database (or apply the data correctly), that's their problem and not a reason to expect an open data project to maintain accurate and current magnetic data as the pole moves. A quick google search suggests there is an MIT-licensed Python library that implements the World Magnetic Model that could be used to calculate up to date magnetic headings from the true headings in the OurAirports database. Maybe you should direct this complaint to the developer of your decoder website and suggest they implement something like that.

Please view the official NAV Canada Canadian airport charts. page 736 of 752 is CYYT showing runway 10/28 as 102°/282° not 086/266

https://www.navcanada.ca/en/cac20251127.pdf

this lists every single airport in canada. that is the official publication that I grabbed the #'s from back in October.

Plan to reject this report. Impractical to add magnetic headings which are fleeting. Runway indicators are changed when official changes are made.

Good day. Every single airport in Canada, uses MAGNETIC not TRUE headings, you are incorrectly reporting every single runway at every single airport in Canada. I have copies of NAV Canada's publications of the runway at CYYT, I can forward them when I receive the response email.

Runway 10/28 for example at my airport CYYT (102°/282° MAG as per the legal published areodrome charts) is being shown as 086°/266° TRUE. I use to use the METAR/TAF decoder website/app that is using your information to help me see what way the winds were blowing across the runway at the start of my shift so I could get a heads up to plan how I was plowing the runway with the winds. But due to the incorrect reporting of the runway, the winds will show it straight down the runway, when we have a cross wind for example.
