If you’re flying high in the sky, it’s useful to know if there’s turbulence, heavy rain, or other nasty weather ahead. Onboard weather radar is a useful tool that pilots use to scope out conditions ahead. [Thomas Scherrer] came into possession of a weather radar display from a vintage aircraft, and decided to tear it apart for our viewing pleasure. [Thomas] only has the display itself, not the radar that would feed it or the power supply to turn it on. The display basically lights up in areas where there were stronger radar returns indicating weather to be avoided.
