Climb and Descent
Altitude PreSelect - Set Target Altitude
The EZ family of altitude hold systems is designed to provide superior performance at an affordable price, with safety features unavailable in competitive systems costing much more. The system consists of 4 main elements - LCD switch module, rotary encoder, electronics module and servo.
An internal airspeed sensor (connected to the pitot system) monitors preset airspeed limits (set by the pilot) to prevent the system from stalling or over-speeding the aircraft. Example: If the pilot enters a very high climb rate, as the airplane reaches the minimum airspeed the autopilot will continue the climb at that airspeed, rather than the commanded vertical rate.
The EZ-3 provides the pilot the ability to pre-select a destination altitude. Once engaged, the system will initiate a climb/descent to the target altitude at a vertical speed that the pilot has previously specified. The vertical rates may be adjusted at any time during the climb/descent.
