Perhaps the most impressive option intended for the 2003 airplanes is Avidyne's FlightMax Entegra, a primary flight display. The large, 10.4-inch diagonal display presents standard flight instrumentation, including attitude direction indicator (EADI), horizontal situation indicator (EHSI), altitude, airspeed, vertical speed and a moving map. The AHRS and electronic air data computer are built into the display case. In addition, the Entegra incorporates the autopilot mode control and a secondary GPS/Nav display. The Entegra Primary Flight Display will add $24,500 to the base price of the upgraded model, designated the SR22B, currently set at $307,500.
