Hartselle, Alabama, United States
This unit (S/N 14456) was removed in working condition for an Aspen upgrade. (The Aspen MFD has a built in GPSS).
This GPSS converter will interface to virtually ALL current GPS receivers and autopilots. It is supplied with the (labled) wiring harness and mating connector as well as the actuator switch. It is compatible with and will operate on all 14 or 28 volt aircraft. The completely detailed specifications as well as the current installation manual and airworthiness data is available online at: www(dot)dacint(dot)com/products/gdc31/ This GDC31 Roll Steering Converter has the most current software version 001B and 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 by
using the 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. Ships for free via USPS flat rate box. |
