    Section 5 Glossary 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.

  • Page 9: Block Diagram

    S–TEC 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 into the Selector / Alerter.

  • Page 20: Selector / Alerter Operation

    S–TEC 3.1 Selector / Alerter Operation 3.1.1 Data Entry Press the DTA switch, such that ENT is annunciated. Any of the following quantities can now be entered into the Selector / Alerter: Barometric Calibration (reference section 3.1.2) Selected Altitude (reference section 3.1.3) Selected Vertical Speed (reference section 3.1.4) Selected Decision Height (reference section 3.1.5) Whenever ENT is annunciated, the Selector / Alerter is decoupled from the...

  • Page 21: Altitude (Alt) Select

    S–TEC Once the barometric pressure setting has been entered, press the DTA switch to make it operational, such that the ENT annunciation is extinguished and the BARO annunciation stops flashing. To change the barometric setting at times other than immediately following power-up, press the DTA switch such that ENT is annunciated.

  • Page 22: Vertical Speed (Vs) Select

    S–TEC 3.1.4 Vertical Speed (VS) Select Press the VS switch. The VS annunciation will appear, along with the selected vertical speed. The latter appears as a number in units of FPM x 100, prefixed by either a "+" to indicate a climb, or a "-" to indicate a descent (i.e., for example, +5 indicates 500 FPM climbing).
  • Page 23 S–TEC Suppose that the aircraft is at an initial altitude of 10,000 FT, with a selected vertical speed of 1600 FPM climbing and a selected altitude of 11,100 FT. The scheduled reduction in vertical speed will be as follows: Altitude (FT) Vertical Speed (FPM) 10,000 1600...

  • Page 24: Decision Height (Dh) Select

    S–TEC 3.1.5 Decision Height (DH) Select This selection activates both an audible alert and a visual alert, first when entering and then when departing a 100 FT window about the actual decision height. The actual decision height does not have to be at the center of this window.

  • Page 25: Loss Of Encoded Altitude

    S–TEC 3.1.7 Loss of Encoded Altitude Should the encoded altitude at the input of the Selector / Alerter ever be lost (i.e., interrupted), then a two-tone audible alert will sound 3 times, while the displayed altitude is replaced by flashing dashes as shown in Fig. 3-1. Thereafter, these dashes stop flashing but remain.

  • Page 26: Autopilot Operation

    S–TEC 3.2 Autopilot Operation Program the Selector / Alerter for the selected vertical speed and selected altitude. On the autopilot, press/hold the VS mode selector switch and then press the ALT mode selector switch, to engage the vertical speed mode and arm the altitude hold mode.
