This two-axis autopilot combines Altitude Hold
with the roll axis functionality of the System Twenty. It is designed
to provide an economical solution for aircraft owners who need Altitude
Hold, but don't want the additional functions of pitch command, vertical
speed control or GS coupling. Independent system does not require interfacing
to the altimeter or atti- tude gyro; derives all input from solid state
absolute pressure transducer and accelerometer. Compact, remote-mounted
pitch computer and amplifier. When engaged, smoothly holds existing altitude;
can be activated during climb or descent. System senses out-of-trim conditions
and annunciates direction to adjust pitch trim. Utilizes single, remotely-mounted
On/Off switch to engage and disengage Altitude Hold.
This product now has STC for Beechcraft 99 Turboprop aircraft including A99A,B99 and C99 models.
