Garmin International Inc. announced last week it received approval that gives thousands of general aviation pilots a chance to replace their old directional gyro system or horizontal situation indicator with the company's G5 electronic flight instrument. When linked together with the appropriate VHF communications and standard or GPS navigation units, "the G5 can be considered primary for displaying magnetic heading, VOR/LOC guidance and/or GPS course guidance, as well as distance and ground speed," Garmin said in a news release.

When linked with a GTN 650/750, GNS 430W/530W or non-WAAS GNS 430/530 navigators, the G5 is also approved as a primary source to display vertical and lateral GPS/VOR/LOC course deviation, as well as ground speed and distance to the next waypoint. The supplemental type certificate for the G5 installation applies to more than 600 aircraft models representing thousands of airframes.

Comprised of a 3.5-inch sunlight readable liquid crystal display (LCD), the G5 electronic flight instrument will display magnetic heading using a new cost-effective magnetometer. Measuring 3 inches deep with its backup battery, the G5 replacement fits easily into a hole left by a standard 3-1/8-inch flight instrument. Installing two G5s can eliminate an aircraft’s dependency on vacuum instruments for heading and altitude information in both VFR or IFR conditions, Garmin said.

The expected price for the G5 DG/HSI electronic flight instrument for certificated fixed-wing aircraft is $2,449. The price includes the install kit, magnetometer, back-up battery and the STC.
