Free To Use: Working Reliable Airspeed Indicator

To Prove it's functionality, use the Wind Settings and see the airspeeds the gauge can read. It measures airspeed by drag on a wing surface and works for measuring the absolute forward airspeed of the aircraft-factoring in wind-. I Colored sections and added markers for quick visual aid in helping give warnings for stall speeds, or indicating landing/takeoff speeds, but feel free to use it or it's principles as you need! IMPORTANT: Gauge will become less sensitive the higher your altitude, thus It's more practical for takeoff/landing indications, just letting you know. (I do hope this helps some people, I was always annoyed that there never was a gauge or dial for showing airspeed, so i built one that can be counted on after many failed attempts to do so.)

Edit: Bottom Panel Weighted for testing purposes, recommend removing for actual usage.

    Yes, airspeed gauges do become less sensitive the higher you go. This is due to lower air density at altitude—fewer molecules go down the pitot tube to impact the diaphragm which moves the needle on the airspeed indicator. Depending on your altitude, there can be a huge difference between your indicated airspeed (IAS) and your true airspeed (TAS). Clipping along at 38,000 ft a 737 may be moving at 490 knots through the air, but only indicates 280 knots on the airspeed gauge. Winds at altitude, which can be quite strong, also impact your groundspeed. The wing part of your build acts as the diaphragm of an airspeed indicator (only because an SP wing is programmed to do so, not because there’s actually wind in SP) does—in fact, this build IS an accurate airspeed indicator for SP. The other thing to note is that in SP, that default “airspeed indicator” is not...its actually a groundspeed indicator, that’s why you see the difference. Clever build.

    @randomusername not sure I translated You correctly, but the bottom panel is what has all the weight. This was for testing reasons, and can be removed to fix this.
