Has anyone installed a GI-275 yet? I see it is compatible with a GTP 59 OAT probe, but can’t find anywhere that says if it actually displays True Airspeed. The manual only says it “calculates TAS.” Does anyone know if TAS can be displayed on a GI-275 configured as a primary ADI? Can TAS be displayed on a GI-275 configured as a primary HSI? I plan to install at least one configured as an HSI and maybe a second as an ADI if the installation quote isn’t too bad, and am debating installing the OAT probe, which only sees worth it if one of the displays can actually show the calculated TAS. Thanks.
