You were using VORs to navigate in the 172, not GPS? Did you compare GPS to what the VOR was reading? I haven’t tested that yet. Were you in the glass cockpit 172 or the steam gauge?
I just loaded up little nav map and connected it to the sim so I could see my position. I had lines drawn off the VORs and compared my plane’s position on the line compared to what the NAV radio gauges were showing in the sim… definitely off by 2-3 degrees.
It also seems more pronounced the further you are from the VOR.
Yes. I had the same problem as well. I was flying VORs across Florida, Alabama into Louisiana. Every time I switched from one VOR to another, I found I was off by many degrees. The first one I thought it was a fluke or maybe I did something wrong. I only had one beer, so it wasn’t the alcohol. But after the 2nd, then 3rd and the 4th. I realized it wasn’t me, something was definitely wrong. Here’s the route I took. MAI V198 LOXLY V241 SJI V20 SLIDD
All of the VORs on this route didn’t line up. I’d fly each leg to the midway point, swap over to the new freq and course, but the needle would be all the way against the side of the gauge. On Air tracked my ugly course adjustments to get back on track. Something is broken with VORs.
My first flight was with the Cessna 208. The 2nd one was with the Carenado PA44. It did the same thing, just before it crashed to desktop about an 1 1/2 into my flight.
Thanks for posting this, I thought I was going crazy.
Can you confirm if you’ve done flights on the same airways before the patch? Trying to work out whether it’s something that the patch has actually caused or whether it’s something you’ve only just noticed.
Secondly what charts are you using to fly the airway radials?
I’m suspecting this issue is due to a problem with the station declinations. If little nav map is using the in sim data to give you radials It shouldn’t create an issue. If it uses some other database then the problem may lay with the Msfs base nav data.
Be sure that little nav map is giving you radials rather than magnetic courses. In the USA these two values can differ significantly as the navigation aids haven’t been updated for years. As an example IDU shows 8E 1965 on the FAA’s eNASR site. The actual Magvar in the area is closer to 3E
