Are radars still useful, with the available weather map? I remember going around a huge cell in Colorado with the secure knowledge that Raton - behind the cell - was wide open. Garmin 430. Back then, couldn't do that with color radar.

IMO, yes. We have the Garmin GWX radar in our Baron and KA. I find we use the radar a lot more in the Baron since we are usually in IMC a lot more navigating cells. Really only use the radar in the KA in climb or descent phases but sometimes enroute. SiriusXM is accurate enough for route planning far out.

My memory was that with multiple cells (like in the DCA-PHL corridor) we were never sure what was behind the cell we were painting, since it absorbed all the transmitted energy. Maybe they are more powerful today?

Onboard radar is better today than it use to be. Not to be a Garmin Fanboy, but Garmin’s onboard radars are the best I’ve ever seen in 35 years of flying.

The best combination is to have both radar and XM. XM for strategic and radar for tactical when you are close in and trying to work around storms. XM is great for knowing what’s behind the closest storms and also for what is hundreds of miles up route.

The delay in XM processing makes it difficult to use for tactical, up close flying and can get you in trouble.

Same. We have WSI at work for weather planning and the onboard wifi (when it works) allows us to update/see the playing field before we get there but the actual routing around cells is done with onboard radar.

More powerful but will also paint a void behind the cell if it knows that it doesn't know what's back there.
 
Bart. Not a particular good pic, but an unplanned engine overhaul has given me time to work on the panel amongst other things.

How's the King stack holding up in the 8GCBC? The KX155 was the bee's knees back in the day. Your old panel didn't look too bad, was the tablet ok or a little clunky? It was something I considered when I did the 8KCAB panel but I ended up using an iPad mini.

Everything still works well on that stack in the 8gcbc, but it's mostly been a hangar queen its whole life; it only gets probably 50 hours a year put on it.

The tablet in my old panel is a Garmin Area 760 portable GPS. It works well, and I'm a big fan of them for a VFR GPS. Pair it with a Garmin GDL52 and get SiriusXM weather and music, ADS-B In, and a digital AHRS. My L-19 Bird Dog is getting a panel update here soon and the Aera 760 is probably going to be re-homed into that panel.

New panel. The shop needs to figure out where to install the GTP 59 temperature probe: the Garmin Installation Manual doesn't help. Anyone have any information or have the GTP 59 installed and can provide a picture?

Install it in a side panel by your knee somewhere that won’t be in the way of anything or used as a handle. Some have run it up into a wing root panel or a screw in panel in the wing. Temp probes can go just about anywhere so they don’t give you instructions on it. One of those “tribal knowledge” things for small aircraft vs a Citation that calls out specific opinions for antennas and probes. First install I called for support on I got a chuckle out of the guy and was essentially told I was overthinking it.

Thanks! We’re a little rationally paranoid because the Certification Branch has to approach my STC application for operation in IFR conditions.

Where did the shop install the GTP 59 temperature probe? Do you have installation information from Garmin to share? The shop installing my panel couldn't find what they need to figure out where it should go in a Super Decathlon. Thanks!

They installed the temp probes (1 for G-5 & another for the GI-275 EIS - Garmin said they couldn’t share 1 probe 😩) in the aft wing root of the left wing, where there is a metal trim piece up against the fuselage. (Between the LH Flap and the fuselage)
I will try to get some pics of the finished install for you.

Thanks! Did Garmin say in writing where to put it?

Not that I know of but I can ask my avionics guy. I think he said that the install just needed to meet general parameters in the STC and that location worked according to his interpretation.

Thanks again. After reading comments I think the idea that my shop had (that Garmin needed to specify a location for the probe for every certified airplane ever made) is...not correct. They specify the locations for those airplanes for which the installation location is critical; it not specified, general guidelines are adequate. I just need to find some "FAA accepted" language to that effect.
