Came across this video showing an MSFS developer camera option which shows a figure for FOV.  In the official forum it has been suggested the FOV shown is in Radians and relates to a vertical field of view.

Using an online FOV tool, my seating positions requires a vertical FOV of 27 degrees.  If the FOV in the video is in radians, that would make my zoom setting in MSFS 88.  Any clever person out there could glance their eyes over the video and work out what the FOV shown represents?

Forgot the video link - fixed 🤭

This post seems to suggest 88 Zoom in MSFS is about right for a 27in 16.9 aspect  screen sitting 70cm away!

Interesting stuff!  I often think my default view and field of view are a bit out.

For those who fly the airbus, the PFD about 6.25" x 6.25".  Sit in front of your monitor, zoom in/out to where that is the size of the PFD physically measured on your montior... that is the correct view.  I do find it interesting that folks fly around with the view looking like your sitting in the jump seat.

Maybe helpful to re-share this. (Since making this I saw a link to someone's custom scenery that you can use instead of Edwards AFB!)

Thank you very much for this link.  I mapped my slew controls to my rudder/joystick to enable smooth and small movements. Once the aircraft was positioned correctly it was easy to set my FOV of 47.5 degrees by using the scenery.  I got the MSFS zoom figure of 83,  which is higher than the 75 I was using.  I bet nearly everybody is using a zoom setting far too small (meaning FOV is far to wide), thus skewing the perception of distance & speed in MSFS.

In my post above concerning the MSFS/developer camera option, it is confirmed that the FOV figure displayed must be in radians and be a vertical field of view.  when I double checked my seating position measurements and converted the on screen developer FOV to degrees, I got 83!

I concur, for any given zoom factor the (virtual) vertical FoV is constant regardless of the aspect ratio of the monitor. (This is how FSX and P3D behave when the 'WideViewAspect' parameter is set to True in either of those applications.) I talk about that in this video:

Hey thanks for sharing 🙂

I'm a bit confused with what number I'm looking at.

I used the FOV calculator (28inch, approx 74cm from screen). This gives 45.5* horizontal.

In sim I've enabled the dev-camera option, according to the MSFS forum Guide the FOV is approx 85 zoom level.

Should I be changing the yellow FOV text number or simply the normal camera zoom level?

For me if I do that the zoom level would be 100

You need the vertical FOV number from the online calculator.  For me the vertical field of view is 27.8.  Convert 27.8 (degrees) into radians by dividing by 57.3. I get 0.485.  I now use the MSFS Zoom control to get the FOV number you see in the developer 'debug/Aircraft/Camera Blend' option to match 0.485. For me I get a zoom of 83.

I double checked this by downloading the custom scenery recommended by @MarkDH above.  In MSFS, go to the airport with ICAO code of 'TRIP'.  Follow this guide at FlightSim.com,  The section of text you are interested with in that article is 'A direct FoV read out circle is now surrounding Parking spot #3. The spacing between posts is one degree with a green post every 5 degrees and a double height green post every 15 degrees. Again use slew (y) to centre the cockpit over the centre post. The stack of horizontal circle surrounding the plane are spaced at 5 metres'

Using slew with the keyboard is too coarse, so I mapped the slew controls to my joystick/rudder pedals. Position your aircraft so the center pole at the head of the 'T' goes through your cockpit seating position.  In the screenshot below, the aircraft needs to come back a bit to get the pole, currently behind the rudder, to go through the cockpit.

Go to cockpit view and make sure all the poles ahead of the aircraft are lined up (position yourself in the center of the cockpit).  Zoom the view in to make sure the same degree marks are at the far left/far right of your view - you may need to use your right mouse button to 'yaw' the view left/right very slightly for this.  All you need to do now is gradually zoom out until your FOV is set - for me I need to see 23.5 degree marks line up each side.  Hey presto, the MSFS zoom function is set to 83!!

Perfect, thank you so much for your detailed response!
