I know the VATSIM environment has weather. The altimeter settings (QNH) from controllers and ATIS vary place to place and day to day like real ones do.
I thought vPilot was pulling enough real-world weather into the sim until today. I was flying on VATSIM in the middle of a big winter high pressure system. I entered 30.37 inches from the ATIS, and my altitude on the ramp read 400 feet too high. I started FSrealWX and the altimeter then read correctly.
I’ve been flying with just vPilot when on VATSIM. Have I forgotten something?
The software setup for VATSIM doesn’t say you need a weather client. I searched forums and the internet about VATSIM, altitude, and altimeter settings, and nowhere says, “You need a weather client.”
vPilot pulls absolutely zero weather into your sim.
The proper place to look for rules on this is the Code of Conduct, which says the following:
B13 Pilots are encouraged to utilize current real-world weather at all times. Pilots must utilize at least the following current, real-world weather parameters throughout all phases of flight:
How that can be achieved depends on your sim. If the sim has a native solution to get the latest real world values then you don’t need to do anything other than enable the appropriate functionality. If your sim doesn’t have a native solution though, then you are required to use some third party real weather solution. I haven’t used FSX in ages, but I think it falls into the latter category.
