An environmental CAS message that I see all too often – this past weekend operating at the Maker Faire the avionics bay got up to almost 100°F and we actually had a part fail (possibly due to the temperature). The pilot seat stayed cool since the air was blowing directly on them but the gunner’s station was getting a little uncomfortable.
Last week I added a circulating fan for the avionics bay. Over lunch today I ordered a second AC unit. I am also working on upgrading the flexible ducts to an insulated, lighter colored solution like the image below.
