Joystick Waypoint Data - Garmin GTN 725 Installation Manual

2.3.10 Joystick Waypoint Data

The GTN unit can accept joystick waypoint data from multiple ARINC 429 sources. If multiple sources
of joystick waypoint data are supplied to the GTN, only valid data from the highest priority source is
used. If the highest priority source becomes unavailable, data is taken from the next-highest priority
source. The priorities of the joystick waypoint data sources are as follows from highest to lowest:
1. ARINC 429 labels 306 and 307 from EFIS or Honeywell EFIS
2. ARINC 429 labels 306 and 307 from Garmin GDU
3. ARINC 429 labels 306 and 307 from EFIS/Airdata
4. ARINC 429 labels 306 and 307 from Radar Graphics
5. ARINC 429 labels 306 and 307 from Garmin GAD 42
6. ARINC 429 labels 306 and 307 from Data Concentrator
