• SBAS Selection (SBAS Softkey is selected)
In certain situations, such as when the aircraft is outside or on the fringe of the WAAS coverage area, it may
be desirable to disable WAAS or MSAS (although it is not recommended). When disabled, the SBAS field in
the GPS Status box indicates DISABLED. There may be a small delay for the GPS Status box to be updated
upon WAAS and MSAS enabling/disabling.
Disabling WAAS or MSAS
1) Select the GPS Status Page.
2) If necessary, press the SBAS Softkey.
3) Press the FMS Knob, and turn the large FMS Knob to hightlight ‘MSAS’ or ‘WAAS’.
4) Press the ENT Key to uncheck the box.
5) Press the FMS Knob to remove the cursor.
• GPS Satellite Signal Strengths
The GPS Status Page can be helpful in troubleshooting weak (or missing) signal levels due to poor satellite
coverage or installation problems. As the GPS receiver locks onto satellites, a signal strength bar is displayed
for each satellite in view, with the appropriate satellite PRN number (01-32 or 120-138 for WAAS) below each
bar. The progress of satellite acquisition is shown in three stages, as indicated by signal bar appearance:
- No bar—Receiver is looking for the indicated satellite
- Hollow bar—Receiver has found the satellite and is collecting data
- Light blue bar—Receiver has collected the necessary data and the satellite signal can be used
- Green bar—Satellite is being used for the GPS solution
- Checkered bar—Receiver has excluded the satellite (Fault Detection and Exclusion)
- “D” indication—Denotes the satellite is being used as part of the differential computations
Each satellite has a 30-second data transmission that must be collected (signal strength bar is hollow) before
the satellite may be used for navigation (signal strength bar becomes solid).
