Can the EFIS be set up to indicate TAS instead of IAS? Since we have pressure altitude, outside temperature and indicated airspeed it should be pretty easy.
Thanks

Re: TAS
I don't recommend replacing IAS with TAS in the airspeed tape either for the same reason Bob wrote. TAS can be displayed on the PFD, however. In the Horizon, go to Primary Flight Display page in the Set Menu. You can configure one of the data fields to show TAS. It was always displayed on the PFD in the Sport-equipped airplanes I used to fly. I liked it just to see how fast I was "really" going on XC trips at altitude.

Yes, I configured the PFD to display TAS as follows:katieb wrote:I don't recommend replacing IAS with TAS in the airspeed tape either (actually, you can't do it anyway) for the same reason Bob wrote.

Upper Left Corner Box >>>> True Airspeed (TAS)
(it's about 40 lines in to the menu)
That's worked well for me.

Re: TAS
Thanks for the Post! I was thinking that I would give Carlos a call and see if he would tell me how to do this, and started reading the new GRT Website and lo and behold there was the info I was looking for. Too Lazy to read the manual!
Thanks once again and I am sure Carlos will appreciate not having to walk me through the process!

Re: TAS
For those who would like all the steps:
Go to the Setup Menu.
Open the Primary Flight Display page.
Scroll down until you see the line "Data Boxes." Make sure this field is set to ON.
Highlight any one of the Data Boxes listed and press the knob to select it.
Scroll through the options until you see True Airspeed.
Push the knob to enter.
Press SAVE softkey when you exit the page.
This will display TAS on the PFD in one of the data fields. For the safety reasons cited above, we don't have an option for people to put it on the airspeed tape itself.
Lloyd I think you'll be pleasantly surprised at the amount of customization you'll find in these display settings now that you're exploring your system!

Re: TAS
Hi Lloyd,
The top Data Box on the Setup Menu/Primary Flight Display page only has room for one field. You now have TAS there. (I said "any line" so I think you just picked the first one on the list!) In the Set Menu/Primary Flight Display page, below the Data Boxes on/off line, you'll see several "Left Box..." and "Right Box..." lists. These display along the bottom of the PFD and are configurable as well. You can put engine, environmental, speed, bearing/distance, all kinds of data in there, including TAS. Most planes I've flown with GRT systems have had the GS in the Upper Left Corner and TAS, OAT, and waypoint information in the lower fields.
