Steve,

The release mentioned the GTN 650/750 will soon have new capabilities (holds, radius to fix, etc...).

Will this include the GTN 625 as well?

Steve,

Disregard. I found it all in the newest description of the GTN 625. Awesome and can't wait (but will have to). Thanks for being on our forum!

When purchasing the GDU 4XX single or dual display, it comes with the GSU 25 (AHRS and Air Data), GEA 24 (EIS), and separately the GAD 29 (ARINC 429).

Doesn't the GSU 73 (AHRS, Airdata, ARCINC 429 and EIS) perform the same function as the 3 units above?

Thanks
Justin

I wondered that too when I saw the GSU 73. As soon as I saw that it has no AOA I didn't investigate further to see if there are other differences.

GSU 73 is their legacy part. They separated it into the 3 other parts, so you could buy what you needed, and also have redundant AHRS without needing redundent EIS or ARINC. GSU 73 works just fine, but newer installations generally have the 3 parts. More things to mount, but much smaller.

Hello Justin,

The GSU 73 is our older sensor unit, which combines the functions of engine interface, ADAHRS,and ARINC 429 interface into a single box. Advances in sensor technology have subsequently allowed us to split these functions into separate boxes in the newest generation of G3X sensor units, which includes the GEA 24 engine interface unit, the GSU 25 ADAHRS + AOA unit, and the GAD 29 ARINC 429 interface unit. This provides the advantage of more flexible mounting options, as well as reduced cost for VFR-only applications which don't need to purchase the GAD 29. Even with the addition of the ARINC 429 adapter, the total cost of a GEA 24, GSU 25, and GAD 29 is still less than a GSU 73, and as Dale noted, also provides the angle of attack measurement capability not found in the GSU 73.
