INTRODUCTION:

This Installation Manual contains installation data, specifications and Instructions for Continued Airworthiness for the DAC International Model GDC31 Roll Steering Converter, Part Number 1049-4000-XX-001( ). Check the DAC International website www.dacint.com/gdc31 regularly for updates to this manual or for additional information.

DESCRIPTION:

The GDC31 Roll Steering Converter with software version 001A is designed to receive RS232 or RS422 serial data from a GPS Navigation System to produce both an analog Roll Sum Steering (RSS) signal and ARINC 429 labels bank angle command and ground speed. The GDC31 Roll Steering Converter with software version 001B (or later) is designed to receive RS232 or RS422 serial data or ARINC 429 Label 121 from a GPS Navigation System to produce an analog Roll Sum Steering (RSS) signal. The GDC31 output signal connects to the heading error input of the aircraft’s existing autopilot. The GDC31 mimics the heading error signal of the aircraft’s installed HSI or DG. The GDC31 does not reduce or otherwise alter any existing safety features of the autopilot, such as bank limiting, rate limiting and protection from a hard over. The GDC31 provides lateral (roll) data only (no pitch data is supplied by the GDC31). The pilot simply selects between heading mode and GPS mode using the supplied switch / annunciator. In heading mode, the autopilot operates as always, tracking the heading bug of the HSI or DG. In GPS mode, the GDC31 RSS signal drives the autopilot’s heading channel. The GDC31 calculates the correct course intercept angle from the data supplied by the GPS, smoothly guiding the aircraft onto the course. The GDC31 then holds the aircraft on the selected course. If the GPS is programmed with Flight Plan data, the GDC31 will calculate the new intercept angle at each waypoint change, intercepting and holding the new course without pilot intervention. The GDC31 is designed to operate with both rate based and position based autopilots.

It extracts Cross Track, Ground Speed and Track Angle Error information from the data stream to compute an appropriate bank angle command to return the aircraft to the Desired Track computed by the GPS navigation system. NOTE: The Bendix/King KLN-89B and KLN-94 GPS Receivers are not compatible with the GDC31 Roll Steering Converter. See Appendix A, SIL GDC31-01.

Analog Output

The GDC31 produces an analog Roll Sum Steering (RSS) signal that drives the heading channel of the autopilot. Phasing and amplitude of the RSS signal is based on the reference input supplied to the GDC31 from the autopilot and the gain and phase settings established by the program pins (refer to Tables 1, 2 and 3). The GDC31 will accept either an AC or a DC reference input as well as reference inputs that contain an offset from airframe ground. The internal circuitry implements a multiplying Digital-to-Analog converter that uses the external reference input to produce the desired signal output amplitude and phase relative to the reference input. Certain installations (Century II and III, for example) will not accept a heading error signal referenced to ground, so require the Isolation Coupler in order to transformer isolate the GDC31 output signal.

Reference Inputs (Excitation)

The GDC31 contains two reference inputs to accommodate the wide range of reference voltages available. Input Ref 1 will accommodate excitation voltages up to a maximum input of 42 volts peak (30Vrms). Input Ref 2 will accommodate excitation voltages up to a maximum of 15 volts peak (15Vdc or 10.6Vrms). The determination of which reference to use will depend on the gain needed to match the autopilot scale factor as well as the maximum expected reference voltage. Certain installations (Century II and III, for example) produce a reference voltage that is floating relative to airframe ground. These installations require the Isolation Coupler in order to transformer isolate the GDC31 reference input signal.

ARINC 429 Input

The GDC31, (-03 model with software –001B or later) receives an ARINC 429 digital input containing label 121. 429 Label (Octal) Description

121 Bank Angle Command (BNR)

GPS Mode Annunciator Control

The GDC31 contains a Normally Open relay contact configured as a SPST switch to control the external GPS mode annunciator. This annunciator is further controlled by external switching and is active when the pilot selects GPS mode in place of heading mode with the external switch. Refer to the typical interconnect diagram

later in this manual. If GDC31 output data is valid, the relay contacts are closed, allowing the mode annunciator to illuminate. If the data is invalid, the GDC31 will cause the mode annunciator to blink at a 1 Hz rate and command the steering output to zero degrees of bank (wings level). The GPS mode annunciator blinks if either the super flag input is invalid or the serial data from the GPS is missing or not the correct format (see Appendix A).

Super Flag Input

The GDC31 reads the Super Flag (14 or 28Vdc) from the GPS receiver. If the flag is greater than 6Vdc, the flag shall be considered valid, if less than 3Vdc, the flag shall be considered as invalid. If the Super Flag indicates invalid, the GDC31 shall produce a steering signal of zero degrees, blink the GPS annunciator relay and invalidate the ARINC 429 label 121, bank command data, and label 312, ground speed data.

INSTALLATION

This Installation Manual is FAA Approved and contains detailed installation instructions for installing the GDC31 into specific aircraft as listed in the AML-STC. There are required FARs that must be complied with and followed to insure an airworthy installation. The Pre Modification Planning section will guide you through these requirements. This section provides details for the installation of the GDC31 Roll Steering Converter, including configuration, wiring, mounting and checkout procedures. Follow the procedures and recommendations found in this section to assure a successful installation. Read this entire section before beginning the installation. Prior to installation, determine the required scale factor and phasing for use with the aircraft’s autopilot. Consider the location of the mode selector / annunciator switch; it should be installed within the pilot’s primary field of view and easily accessible by the pilot. Complete an electrical load analysis in accordance with AC 43.13-1B, Chapter 11 prior to starting the aircraft modification to insure the aircraft has sufficient load capability. Complete an aircraft weight and balance prior to aircraft modification to insure the aircraft has sufficient weight and CG margin.

Pre Modification Planning

Annunciator/Switch The GPS/ HDG annunciator switch should be located near the HSI/ DG or alternately, near the existing autopilot mode annunciators. Power Requirements A suitable location will need to be determined for the RSS circuit breaker. It is recommended that power to the GDC31 be supplied from the same source and the autopilot, typically the avionics buss.

Equipment Interfaces

GPS The GDC31 provides steering command through the HDG Datum of the autopilot based on GPS input. The GPS must be capable of providing either ARINC 429 label 121 or RS232 data in “Aviation Format” described in section appendix A and appendix B-ARINC 429 input of the manual. Autopilot The GDC31 is compatible with the autopilot models listed in the Limitations Section of the GDC 31 STC. During installation, the GDC31 in configured to emulate the Heading Datum output of the existing HSI or DG. Refer to the wiring diagrams in Section appendix E of this manual. No modifications to the autopilot wiring are necessary. The GDC31 will use the same Heading Datum reference feeding the HSI or DG. As part of this modification, the HSI or DG Heading Datum error signal is re-wired through the supplied GPS / HDG annunciator switch, enabling either the current Heading Datum error signal of the GDC31 steering signal to feed the autopilot heading datum input

NOTE: The following setup procedures are for diagnosing interfacing problems.

Steering Output Scale Factor Determination

The GDC31 is designed to mimic the heading error signal produced by the existing HSI or DG, so it can operate with the wide variety of autopilots in current use. These various autopilots employ a wide range of reference voltages and scale factors to interface with the array of HSI and DG control heads. Reference voltage, or excitation, is the autopilot signal used to excite the Heading Select bug in the HSI or CDI. As used in this manual, scale factor refers to the autopilot’s response to the heading error input signal, expressed in volts per degree of bank. Examples are 200mv/deg and 60mv/deg. Examples of excitation voltage are 26Vac and 15Vdc. The GDC31 first computes the bank angle using data from the GPS. It then uses the reference voltage along with the scale factor setting (gain setting) to produce a signal that feeds into the autopilot’s heading error input to produce the desired bank angle. The GDC31 has ten (10) choices for scale factor, selected with a combination of program pins (3 each) and reference inputs (2 each). Tables 1 and 2 describe the program pin combinations for the various scale factors. To determine the appropriate setting for a given autopilot, first determine the autopilot excitation amplitude in volts (AC or DC). Next, determine the autopilot scale factor from the autopilot maintenance data. The scale factor needs to be expressed as volts/degree of bank. Divide the scale factor by the excitation (scale factor / excitation voltage). Then look in Tables 1 and 2 for the nearest Scaling value to the one just computed. If the gain is set too high, the commanded course intercept will be overly aggressive. For 90-degree course changes, too much gain will often cause the aircraft to turn inside the new course then S-turn back to capture the track. If the gain is set too low, the commanded course intercept will be sluggish. For a 90-degree course change, too little gain will often cause the aircraft to overshoot the desired course then S-turn back to capture the track. Some autopilots limit the maximum bank angle to less than the 30 degrees, 22 degrees for example. In these cases, the aircraft will exhibit the symptoms of too little gain because the aircraft cannot turn sharp enough to capture the track without overshooting. Examine the attitude indicator during a 90-degree course change to verify that the aircraft banks to 30 degrees, or in the case of rate based autopilots, to a standard rate turn.

Phase Selection

The GDC31 will accommodate steering signals that are in phase with the reference or out of phase with the reference. For DC heading error signals, in-phase means a positive error signal produces a right turn, a negative error signal produces a left turn. Determine the correct phasing from the autopilot maintenance data then wire P1-13 accordingly. If the phasing is incorrectly wired, the autopilot will turn the opposite direction when coupled to the GDC31 Roll Steering Converter.

APPENDIX A – RS232 AVIATION FORMAT

The GDC31 accepts data in the RS232 Aviation Format produced by most GPS panel mount receivers. Various manufacturers refer to this data as RNAV, KING or MAPCOM. The following table contains the minimum data set required by the GDC31. The GDC31 is designed to disregard additional data records transmitted from the GPS. NOTE: The Bendix/King KLN-89A and KLN-94 GPS Receiver update rate of track is too slow to maintain aircraft on course. If connected to a KLN-89A or KLN-94, expect a 3-degree track angle error left and right of course over a 1 – 2 minute period. GPS Receivers that supply the following minimum data set and any of the previously mentioned baud rates should be compatible with the GDC31. Insure the GDC31 is configured for the correct baud rate (refer to "Serial Baud Rate Selection" located earlier in this manual).
