Garmin autopilot certified in Navajo Chieftains

By General Aviation News Staff · May 30, 2023 ·

The GFC 600

Garmin has received FAA Supplemental Type Certification (STC) for the GFC 600 digital autopilot in Piper PA-31-350 Navajo Chieftains.

Additionally, Smart Rudder Bias is now certified for PA-31-350 aircraft equipped with the GFC 600 autopilot, company officials noted.

Autopilot

The GFC 600 digital autopilot is intended for piston single/twin-engine and turbine aircraft that have a wide range of speed and performance characteristics. In addition to traditional autopilot capabilities such as altitude hold, vertical speed and heading modes, the GFC 600 also includes:

  • Premium functions and advanced capabilities such as altitude pre-select and indicated airspeed hold mode
  • VNAV capability when paired with a GTN or GTN Xi series navigator
  • Dedicated LVL button can automatically engage the autopilot to restore the aircraft to straight and level flight with one press
  • Support for Smart Glide that can help automate tasks and reduce pilot workload in engine power loss events when paired with a GTN Xi series navigator and Garmin attitude indicator
  • Underspeed and overspeed protection
  • Select, couple, and fly various instrument approaches, including GPS, ILS, VOR, LOC and back course approaches when paired with a compatible Garmin GPS navigator
  • Yaw Damping mode minimizes yawing oscillations while also helping to maintain coordinated flight
  • Electronic Stability and Protection functions independently of the autopilot and works in the background while the pilot is hand-flying the aircraft to help avoid inadvertent flight attitudes or bank angles by nudging the pilot to return the aircraft back to an appropriate flight attitude

Smart Rudder Bias

Smart Rudder Bias provides pilots assistance against the hazardous effects of one-engine inoperative events when the aircraft is appropriately equipped, according to Garmin officials.

The system continuously monitors engine parameters using Engine Indication System (EIS) data displayed on a G500 TXi or G600 TXi flight display and activates when the system detects a predetermined power differential between each engine.

Once activated, rudder force is dynamically adjusted to aid a pilot in providing enough force to the rudder to help control a sideslip. A yellow annunciator for the associated inoperative engine is displayed along with autopilot annunciations on the G500 TXi or G600 TXi flight display, helping the pilot more quickly identify the issue, company officials explain.

Smart Rudder Bias requires a G500 TXi or G600 TXi configured as a primary flight display (PFD) with engine indication system (EIS) data, which can be shown as a strip on the G500 TXi or G600 TXi, or on a separate dedicated TXi EIS display. Additionally, Smart Rudder Bias requires the yaw axis option be installed on the GFC 600.

The GFC 600 digital autopilot for the Piper Navajo Chieftain is available immediately. Prices start at $23,000.

Garmin continues to add additional aircraft models to the STC list for the GFC 600 autopilot. To view the most up-to-date aircraft STC list, including certifications that are expected to begin in the next 12 months, or to express interest in a specific aircraft make/model, go to Garmin.com/GFC600.
