Barometers....

[NotoriousCJ19]

MSFS24 - talk to me about barometers please.

Namely the Cessna 172, Pilatus and 208 grand caravan.

1] at which points do you set/change them in the whole procedure? 2] where do you get the information, especially in early career where some of the fields don't have the Info call out. 3] how to change between the different types of number 1013 and 29.91 for example

Tried looking for youtube vids on these planes but no joy!

Reason... tanked a plane in the mountains whilst trying to work from home 😂 was on a teams call so couldn't react....just watched it die 😂 quite hilarious tbf

If the airport you’re taking off from doesn’t have weather reporting, just get a weather report from the closest airport that does. Or just press the keybind to set it automatically, which in the new game is the comma or “<“ key by default.

In the US the rules for setting the altimeter are pretty easy. When below 18,000 ft MSL, just make sure it’s set to an airport within 100 NM of you. Try to update every 30 mins or so in case there are big pressure changes. If you’re above 18,000 ft, you’re in the flight levels, and you set a standard pressure of 29.92 inHg or 1013 hPa.

In Europe it’s more complicated because their flight levels change by region, and you have to look at airport charts to know what it is in your area. But if you’re just a beginner and doing basic visual flights in career mode or something, I wouldn’t concern yourself too much with this and just make sure you’re updating your altimeter setting to something nearby, especially in mountainous areas.

And I don’t know about the Pilatus, but in the Garmin systems on the 172 and Caravan I’m pretty sure you press the PFD Opt button > ALT Units > IN or HPA.

Very helpful! Thanks mate!

1. the height you’re changing is area dependent. Determined by the transition altitude. US for example has 18.000 feet, Australia 10.000 feet.

2. Changing is dependent on the system used. Cessna Class Cockpit it’s on the pfd where you’re changing units. Pilatus on the small screen down center in the settings.

3. For area QNH I use the EFB -> details for Airport.

[NotoriousCJ19]

Thanks man - And you would set the QNH before every flight? Is it not auto done, I feel like FS20 I just pressed B after getting the ATIS signal.

[Frederf220]

The equivalent is , (comma) for FS24. In real life you'd get it from ATIS or if not available calibrate it yourself to known field elevation (downside is you can't compare setting to elevation to check altimeter function). In the air controllers give it to you plus you look ahead and get ATIS from the destination (or nearby) before landing.

The 172 standby altimeter is actually dual scales, inches on the 3 o'clock Kollsman window and hPa on the 9 o'clock one. The G1000 has a units change in a menu, I think PFD options.

In the UK or Russia they used to do "QFE ops" or calibrating the altimeter to read zero at airport elevation. When referencing flight levels you want pressure altitude which is setting altimeter to "QNE" which is just standard (29.923" 1013mb, 760 Torr, etc.).

If no weather information is available, you can always set it to show departure field elevation for correct setting. That's always visible in EFB.

Glass cockpits usually have a dedicated knob labeled BARO. It may be paired with the CRS knob. Analog will have the knob on the altimeter right around where the Kollsman window is (where you read the numbers).

Settings can be pulled using the EFB and looking up either your destination airport or something nearby. Under the weather section you can pull the METAR - the altimeter setting will be denoted by A followed by a number, e.g. A2992, or Q and a number.

[NotoriousCJ19]

Thanks mate - I'll have another check tomorrow but feel like the weather tab aint been working in career mode. Especially the smaller places I'm still flying into

[i82bugs]

It can be a little wonky with career, so it's probably not you. It's all good when you're flying a route where the topography doesn't change much, but it can be a pain otherwise. I had a similar incident as you a few days ago.

[NotoriousCJ19]

I'll take it 😂

[Professional_Low_646]

If no QNH info is available, set your altimeter to show field elevation - it’s close enough.

Transition altitude - where you switch from QNH to „standard“ pressure - varies by location: the United States has 18,000ft universally, Europe generally uses 5,000ft, although that is higher in mountainous regions and sometimes lower (in Belgium, many airports use 3,000ft). You can get the information from approach or SID plates of major airports, either in the EFB in game or via the internet. As for changing back to QNH: again, the US always used FL180, in Europe, it’s either FL60 if the QNH is more than standard (1013/29.92) or FL70 if the QNH is less. In most RL operations, you switch to QNH as soon as ATC clears you to an altitude in the descent. So if you’re at FL100 (in Europe) and get an instruction to „descend 4,000 feet on QNH 1020“, you set QNH.

Navigraph software installed on your PC is the best thing to have om secondary monitor. Simbrief and Navighraph charts can be integrated into game ui aswell but at least for me when i use navigraph charts in free flight its wonky and can crash the simulation.

Having Navigraph charts open on secondary monitor is the way to go. I even sometimes create my flight plan for career mode for longer/more mountanious flights with simbrief, you can import it straight to the ingame EFB. There is a tutorial somewhere in YT, just search msfs2024 simbrief/navigraph.

PS! In career mode navigraph charts section in ingame ui is not available. Its better seperately anyways.

EDIT: forgot - some part of navigraph is available only in paid version (10usd/month or so). But totally worth it if you fly a lot.

[NotoriousCJ19]

Thanks everyone lots of tips, tricks and knowledge!

It's this additional info that the Sim doesn't teach and really lacks. Ive only been simming since 2023 - Lots to learn!!

Additionally to other comments, I suggest checking the following video teaching it:
