Hello, I am wondering if it is possible to say set the weather for a specific place in the sim but have the weather everywhere else be live? For example, if I want to do a flight might want the departure airport to have custom weather but then have live weather everywhere else, so I can still follow the SIGMETs from the flight planner for most of the flight.
Thanks
Not possible in the way you want but you could always set up the weather you want for departure then switch to live after you take off. You can make that a bit more seamless (less immersion breaking) using //42’s Flow so you don’t need to go into the pause menu or have the giant popup window to switch.
And does real weather take into account pressure changes, to display correct altitudes?
Yes it does but you’ll need to change the barometric setting on the altimeter in the airplane so the correct altitude is displayed, either by pressing the B key on the keyboard, or by interaction with the altimeter setting knob.
Thank you, I think this is the best way to go for now. Hopefully if we get something like Active Sky then we can set weather for specific areas but have everything else be live
Yes I know that, but what I don´t know is if pressure changes as you fly, and hence the altitude, as in real life.
Do you mean that the pressure outside the plane changes with altitude?
I know there are some planes that model cabin pressure, with oxygen starvation above a certain altitude in unpressurized cabins. And piston aircraft almost all require mixture control, as altitude creates the need for leaner mixture to retain performance. And of course the displayed altitude depends on adjusting the altimeter to local reported barometric pressures.
I don’t know whether those things are mapped to barometric altitude cues, or simply linked to a mean altitude table.
I guess you are right about “linked to a mean altitude table”. All is about my ignorance about how “real weather” option acts in MSFS.
In live weather atmospheric pressure varies across the globe, ie in Edinburgh it’s 998 hPa and in Stuttgart it’s 1,017 hPa. As you fly on autopilot from Edinburgh at 29,000ft indicated on the altimeter, the pressure is increasing and you are changing altitude. ATC will prompt you once you are 300ft above or below your assigned alt, and the reason for the discrepancy is usually failing to reset the altimeter.
Aircraft altimeters are set to “Standard Baro” above the transition altitude to ensure traffic separation vertically. In reality these aircraft will be gaining or losing altitude as pressure changes, but they are all doing so in unison and retaining the required separation.
All this is replicated in the sim when flying with real time weather.
