As if the mag variation mattered. Not even the best autopilot can hold a heading that accurately
It matters in some other parts of the world (as I'm sure you're aware). When I was in the USA, magnetic variation was about 13 degrees. Runway headings on the map really confused me until I realised what was going on. What with that and all the weather forecasts in UTC, which was 8 hours different from California time..... Arggghhhhh. I started to realise just how easy we have it in the UK, relatively speaking.
