Stec 30 Operations Manual Is Difficult
The manual is difficult to follow. It was not a straight forward learning experience. 52ppThe GENESYS 30 visible spectrophotometer brings you intuitive design.During my checkout training in N716CD I learned how to use the STEC 55X autopilot and the preselect unit.

Autopilot UnitNsd 360 Installation Manual. (That’s what’s called a legal disclaimer ^). Please refer to the manual for details beyond the scope of this discussion. This article is intended to give you an overview of the operation of the unit. What follows is the fruit of that experience, hopefully in a more digestible form than that found in the manual.
Once you get to your desired altitude and level off, you hit the ALT button to capture and hold it. You press the HDG or NAV buttons to engage the autopilot’s ROL mode, then you can press the VS button to enter vertical speed mode using the rotary knob to set your desired climb or descent rate. The autopilot unit by itself is pretty easy and intuitive to operate. The STEC 55X autopilot unit sits in the console right below the #2 GPS, and above the transponder.
Chris I would appreciate the wiring diagrams. For now we will focus on the basic VFR functions of the autopilot.Cirrus Design Section 9 Pilot s Operating Handbook and FAA Approved Airplane Flight Manual Supplement for S-Tec System Thirty Autopilot When the S-Tec.Mike thanks for the Stec manual. There are also functions for flying IFR approach procedures, but I’ll leave the discussion of those for perhaps a future article.
The autopilot unit is really that simple to operate. Shutdown but got it in the mail a few days ago so I will be able to get to the fly ins again.Now, if that functionality is all you need, then you can stop reading. Took my flight physical on Sept 30 th and then the Gov.
4 Page iii NOTE: Use of polarized eyewear may cause the display to appear dim or blank.Right above the altimeter on the instrument panel is an odd-shaped instrument with an LCD display, several buttons and a rotary knob.This device is an accessory to the autopilot and provides the “altitude preselect” function, among other things. Altitude PreselectorGarmin G5 Electronic Flight Instrument Part 23 AML STC Installation Manual 190-01112-10 Rev. If you want it to automatically sequence to subsequent legs, you must press the NAV button a second time to enable the GPSS (GPS Steering) mode. Another thing to be aware of if you have programmed a multi-leg GPS course into the GPS navigator, then pressing NAV on the autopilot unit will cause the autopilot to intercept and follow the CURRENT leg. There is no “AP Engage” button, and the only method for disengaging the autopilot is to press down on the trim hat on the side stick.
It is important to understand that any changes to the ALT, VS, DH or BARO parameters will not take effect until you exit the “data entry” mode and enter the “operate” mode by pressing the DTA button, thereby turning off the ENT segment. If the ENT segment is off, the unit is in “operate” mode. If the ENT segment on the preselector’s LCD display is on, the unit is in “data entry” mode. These modes are selected using the DTA button on the preselect unit. Pressing the right buttons to make it do these things…well, those are the secrets that I hope to reveal for you.First off, you need to realize that the preselector operates in 2 distinct modes we will call them “data entry” mode and “operate” mode.
This puts the preselector into “data entry” mode. If the ENT segment (preselect unit) is not on, press the DTA button on the preselector to turn on the ENT segment. The preselector will continue to “operate” while in data entry mode, but the preselector values available to the autopilot unit will be those that were in force before entering data entry mode.So, you’re sitting on the ground ready to takeoff and you want to set up the autopilot/preselector for a predefined cruising altitude and rate of climb.
Press the VS button (preselect unit), and use the rotary knob to select the rate of climb (in 100s of feet). Pull for 100s of feet, push for 1000s (separated by a decimal, i.e. Press the ALT button (preselect unit), and use the rotary knob to set the desired cruising altitude. Pull the knob for 1/10ths, push for whole inches.
The ALT and VS segments on the autopilot unit will turn on, signifying that the autopilot unit is in capture mode, and using the data from the preselector for target altitude and vertical speed. Now, press and hold the VS button on the autopilot unit, and while continuing to hold the VS button, press the ALT button also on the autopilot unit. After takeoff, and after the aircraft is configured for stable climb (obstacles cleared, flaps up, etc.), engage the ROL mode of the autopilot using either the HDG or NAV mode. This puts the preselector into “operate” mode.
For some reason, it is not necessary to press the DTA button to adjust the vertical speed, only the VS button. During climb or descent, the vertical speed programmed into the preselector can be adjusted by pressing the VS button (on the preselector), then setting the new vertical speed using the rotary knob. As long as the autopilot hasn’t yet captured the previously programmed altitude, it will capture the new altitude once the aircraft arrives there. During climb or descent, the target altitude can be adjusted by pressing the DTA button, then the ALT button (on the preselector), then setting the desired altitude, then pressing the DTA button again to lock the altitude in.
It is possible to program a target altitude on the preselector and use the vertical speed processor in the autopilot. In order to program a new altitude and/or vertical speed (from the preselector), those parameters must be programmed into the preselector, then transferred to the autopilot by pressing VS and ALT again (on the autopilot). Small changes can be made to the captured altitude using the rotary knob on the autopilot (+/-20′ per click). The VS indicator on the autopilot will turn off, and the ALT indicator will remain on.
In order to enable these tones the ALR segment on the preselector’s display must be turned on. The preselector is capable of issuing a tone through the audio system when you cross within 1000′ and 300′ of the target altitude. If no vertical speed is displayed on the autopilot, then the vertical speed can be adjusted by selecting the vertical speed on the preselector (VS button), then adjusting the vertical speed using the rotary knob on the preselector. After linking the preselector to the autopilot using the VS/ALT buttons on the autopilot, if the vertical speed is displayed on the autopilot, then the vertical speed can be adjusted using the rotary knob on the autopilot. The vertical speed processor in the autopilot will climb or descend at the programmed rate all of the way to the target altitude, then abruptly change the climb/descent rate. The only difference between the vertical speed processor in the preselector and the one in the autopilot is that the vertical speed processor in the preselector will smoothly reduce the rate of climb/descent as the target altitude is approached.
