1.2 Purpose
This Pilot's Operating Handbook (POH) provides Pre-Flight and In-Flight
operating procedures for the S-TEC ST-360 Altitude (ALT) / Vertical Speed (VS)
Selector / Alerter.
Note:
This POH must be carried in the A/C and made available to the pilot at
all times. It can only be used in conjunction with the Federal Aviation
Administration (FAA) approved Aircraft Flight Manual (AFM) or Aircraft Flight
Manual Supplement (AFMS). Refer to the applicable AFM or AFMS for
A/C specific information, such as unique ground tests, limitations, and
emergency procedures.
Note:
The Selector / Alerter is a tool provided to aircraft owners, that serves to
assist them with cockpit workload management. The ability of the
Selector / Alerter to provide optimum assistance and performance is
directly proportional to the pilot's knowledge of its operating procedures.
Therefore, it is highly recommended that the pilot develop a thorough
understanding of the Selector / Alerter and its operating procedures in
Visual Meteorological Conditions (VMC), prior to using it under Instrument
Flight Rules (IFR).
1.3 General Control Theory
The Selector / Alerter can be used with the following S-TEC autopilots:
System Fifty Five X
System Sixty Two
System Sixty Five
Pitch Stabilization System (PSS)

The Encoding Altimeter / Blind Encoder sends the encoded altitude to the
Selector / Alerter. The encoded altitude must be converted to the true altitude,
through barometric calibration.
The selected altitude and selected vertical speed must be programmed int o the
Selector / Alerter. Thereafter, upon engaging the autopilot's vertical speed mode
and arming its altitude hold mode, the aircraft will attain and hold the selected
vertical speed. As the aircraft approaches the selected altitude, a scheduled
reduction in the selected vertical speed will automatically occur. This enables
the aircraft to transition from vertical flight to altitude capture, without adverse
acceleration. Once the selected altitude has been captured, the autopilot's
vertical speed mode will disengage and its altitude hold mode will engage. The
aircraft will then hold the selected altitude.
