The sim can get pretty hot inside, it’s an enclosed space surrounded by computers, monitors and electronics. So I put a portable air conditioning unit in and then used ducting to pipe it into a vent inside the aft cockpit compartment! The vent has louvers so you can angle it into the cockpit or straight down if it’s too much. This combined with the Captain and First Officer fans I put in will make it nice and comfy inside the sim! Thanks to Co-Pilot Coral for helping me with the install!
