The Mid-Continent Instruments and Avionics MD23-342 FLEX® is a 2-inch solid-state digital attitude indicator. It presents four primary functions on a daylight-readable LCD: attitude, slip, turn rate and heading. The instrument provides independent attitude information without requiring GPS, a magnetometer or airspeed input.

Designed around MEMS gyro and accelerometer technology, the MD23-342 features a single push-and-turn control, selectable panel tilt and roll-offset settings, and manual/external lighting control or automatic dimming through an internal photocell. Heading information interfaces with primary avionics through an external ARINC 429 input.
