Just released enhancements for Garmin’s G500 TXi and G600 TXi flight displays target Cirrus and Piper Meridian aircraft models.
Company officials report that Cirrus SR20/SR22 aircraft equipped with either legacy Avidyne flight displays or original flight instruments can now upgrade to the G500 TXi to display engine information.
GFC 500 autopilot support is also expected for SR22/SR22T aircraft later this year. It will include features such as Garmin’s Electronic Stability and Protection (ESP), descent vertical navigation (VNAV1) and more.
Also new, the turbine-engine equipped Piper PA46-500TP Malibu Meridian is compatible with the Engine Indication System (EIS) on the G500 TXi and G600 TXi flight displays.
The Piper PA46-500TP is the latest addition to a growing list of aircraft that are capable of interfacing with the TXi system to display EIS information, according to Garmin officials.

Pratt & Whitney PT6A turboprop engine display compatibility is available for several popular aircraft models, including the Cessna 208/208B, Daher TBM 700/TBM 850, and the PA46-310P/350P JetPROP.
Features of the EIS system for turbine aircraft include engine timers, exceedance recordings, engine indications, as well as wireless data logging that combine to improve engine efficiency and reduce maintenance costs, Garmin officials said.
Additional features of the latest TXi upgrade include:
- When the G500 TXi & G600 TXi is paired with the GTNTM/GTN Xi series and the GFC 500 autopilot, the system performs automatic GPS-to-LOC switching.
- Percent power can be viewed on the TXi displays for single-engine and twin-engine pistons, as well as turboprop aircraft.
- Fuel quantity display compatibility expanded to include aircraft that have up to six fuel tanks.
- Select twin Cessna aircraft with four fuel tanks are now capable of displaying fuel quantity on the G500 TXi and G600 TXi.
- Fuel imbalance caution and alert advisory messages can be configured by a Garmin dealer during installation.
- The TXi displays are now approved for interface with CiES fuel sensors.
- A new vacuum gauge option supports aircraft that maintain a vacuum-driven standby instrument and systems.
- TXi EIS bar gauges can be configured to display a digital value for piston aircraft.
- Tach timers are now available for piston aircraft.
