Versatile Flight Instrument with Built-in Backup Battery
The KI 300 Electronic Attitude Indicator is a panel mounted attitude, airspeed, altitude, vertical speed and slip instrument. The instrument is self-contained and directly incorporates all of the sensors required to measure and display the listed flight parameters. All information is displayed on a color 3.5” diagonal LCD display in traditional aerospace symbology. The unit also contains a rechargeable battery capable of providing continued operation in the event of aircraft electrical failure.

AFFORDABLE UPGRADE
AeroFlight's KI 300 and KA 310 replaces the KI 255, KI 256 and the KG 258 with no changes to your instrument panel. KAP 100, 150, 200 and KFC 150, 200, 225 autopilots are natively supported using the AeroFlight KA 310 autopilot interface. The autopilot can be aligned and the air data computer calibrated, both with AeroFlight in the panel, simplifying installation and maintenance. This upgrade lets you save the typical $4000 to overhaul mechanical gyros every 800 hours, and gives all of the information in a primary flight display at a much lower cost.
RELIABILITY AND SAFETY
With no mechanical moving parts, AeroFlight has a MTBF (mean time between failures) of 10,000 hours, which means it will likely never fail for the life of your airplane. It is certified as sole source replacement attitude source for an autopilot, and can also serve as a perfect backup indicator.
