Falcon50 Question
Please excuse the intrusion. I am not a professional pilot, but rather just an old guy who doesn't fly anymore but once had a PPL and an instrument rating.
Below is a diagram of part of the center console of a Dassault Falcon50 (click to enlarge). My question has to do with one of the switches (and/or lights) in the group of four you see just below the throttles. Despite searching the web and some documentation I have on the Falcon50, I haven't been able to find any mention of the use or purpose of the UNARM ON switch (or light). The only thing I can think of that might be armed or unarmed is the reverser on the middle engine, but that is only a pure guess. If anyone can enlighten me on the purpose of this switch/light I would appreciate it.
Thanks much.
