“What type of Mode S Transponder does Lear 45XR, serial 289 have?” I asked.
“Like I’ve been saying, it’s an integrated avionics suite,” Matt responds.
“Okay… How do I show that? Which is a not-so-savvy way of conveying I have no idea what that means other than the implied meaning that it’s integrated into something else.
“Let me show you.” Matt’s patience is always welcome because I ask him most of my questions and I try really hard not to ask the same question twice, but it does happen on occasion.
He goes on to explain that instead of having a separate display for each piece of avionics, they are wired into one display.
Later on that afternoon, Johnny walks into my office, and I decided to share my new knowledge. He’s also very patient (that’s the theme in the office luckily J). I realized I was only halfway on the road to actually knowing what RMUs were (what displays all of the integrated avionics). I had no clue what they looked like or how to point them out. He had me open a photo of the cockpit and explained exactly where those displays live.

Long story short, the Lear 45XR has Dual Mode S Transponders that are integrated into the Dual RMUs.
I learned something new – the streak continues!
