If I add OAT to a G5 to GTN-650 integration will I be able to get calculated DALT, TAS and Winds on a GTN-650? It would be nice to nice to know the wind direction and speed at a glance.

The GTN -650 pilot's manual states, "Density Alt / TAS / Winds — indicates the theoretical altitude at which your aircraft performs depending upon several variables, including indicated altitude (Indicated ALT), barometric pressure (BARO) and total air temperature (TAT; the temperature, including the heating effect of speed, read on a standard outside temperature gauge). This item computes true airspeed (TAS) and density altitude, based upon the factors above. Also, this feature determines winds aloft — the wind direction and speed — and a head wind/tail wind component, based on true airspeed, aircraft heading (HDG) and ground speed."

A GNS-4/5x0 calculates air data with input from an Aspen. Hard to imagine the GTNs deleted the capability. Dunno if the G5 exports data in a format that a GNS can read.
 
Not quite because for some reason big G won’t accept the IAS from the G5 as CAS, last I saw, they were going to have to investigate.
 
I just asked the avionics shop to check on IAS as CAS. They have to research.
 
Av Shop installed an OAT sensor connected to my GTX-345 ADS-B transponder. This transponder calculates density altitude while displaying OAT. Pretty handy out here in the mountains.

Nice to have DAlt readily calculated, how ever you accomplish it.

Is there a certain sensor for that, or just one already connected to your aircraft? I already have a digital OAT connected to my CGR-30P. Wondering how that is all wired up to your GTX345.

My avionics shop got back to me and stated that I will not get automatically calculated wind speed and direction on the GTN-650 if I add an OAT probe. They said that an Air Data Computer is needed. May be due to CAS vs IAS as stated by TeeJayEvans above. I can add OAT to the gtx-345 as stated above but this will only give me density altitude. I may add OAT to the 345 depending on cost.
 
Does anyone know if the OAT probe from a JPI 830 can feed either the GTN or the GTX345? With the new G5 version 6.20 that was just released you can get TAS and Wind Direction support now. I have a JPI 830 and it displays OAT and the FF from that unit is showing up on the GTN750 so I'm trying to figure out if I have to buy a secondary probe or if I can somehow feed either JPI data for OAT with the FF Data already being sent or use a seondary wire off the JPI OAT sensor and connect to the pin in on the back of the GTX 345.

I have FF and OAT in my 750 from my JPI830 but the issue is still that the G5 won't send IAS as CAS to the 750. I have to manually input CAS into the calculation page.
 
If you don't have a G5 and G3X or TXi, I don't think most of the new things work.
