Totally useless you say, and thus totally indispensable? This mod just add a Density Altitude digital display on the two holding points at Big Bear Airport. On 26 holding point, it also adds the information sign regarding noise abatment. And that's all!
This is NOT a mod airport. If you look for Big Bear L35 airport, choose the great Josue's work : https://flightsim.to/file/3237/l35-big-bear-airport
If you look for enhancement of the lake area, go there for the fligjtsimdude nice mod : https://flightsim.to/file/6334/big-bear-polys
These two sign's mods are just an exercice and kind of training for my whole design workflow (Gimp, Blender, MSFS...) in Flight Simulator.
This is fully compatible with L35 Big Bear Airport by JosueMejia. I asked the author if he wants to add this small object in his scenery but I didn't get any reply yet. If you're in touch with Josue... Let me know!
This mod is also compatible with Flightsimdude lake enhancement.
Caution: as in real life (last checked last 17th February 2021) the display is out of service and display... nothing ;)
