5.6.4 ILS Flight Check (GNS 530W)
1. Tune an ILS at the local airport.
2. Verify the audio ident and audio quality and verify that no objectionable electrical interference
such as magneto noise is present.
3. Verify the Morse code decoder IDs the station (95% probability).
4. Fly the approach.
5. Verify NAV flag, GS flag, and CDI and VDI are operational.
6. Verify BC annunciator.
5.6.5 Autopilot Flight Check
1. Enter and activate a flight plan on the 500W Series unit. For the GNS 530W ensure that GPS is
selected on the CDI. Engage the autopilot in the GPSS mode. Verify that the autopilot flies the
course.
2. Disengage the autopilot and fly off course. Re-engage the autopilot (in GPSS mode) and verify
that it correctly intercepts the course and continues to fly it.
3. Turn off the autopilot GPSS but leave the autopilot engaged in NAV mode. Verify that it
maintains the current course.
4. (GNS 530W Only): Reselect the GPSS mode on the autopilot. Press the CDI key to select VLOC
on the GNS 530W. Verify that the GPSS mode disengages.
5.6.6 TAWS Audio Flight Check (for units with TAWS only)
NOTE
The TAWS volume needs to be loud enough to ensure that aural alerts are
audible under all anticipated noise environmental conditions. This check
verifies that TAWS aurals can be heard during flight, but the ambient noise
conditions under which it is verified are not worst-case. Consequently, the “Five
Hundred” callout should be louder than is required for the conditions under
which it is verified.
1. Set up for an approach to the airport.
2. During the approach, at approximately 500 ft AGL, the “Five Hundred” callout will occur.
Verify that “Five Hundred” can be easily heard and understood.
5.7 Database Check
Check the aviation database to ensure it is current. The database information is displayed during the unit
display start-up sequence. To check the database:
2. Turn off the 500W Series unit and then turn it on. The 500W Series unit will go through its
normal start-up sequence.
3. Wait for the Aviation Database page to be displayed.
4. Verify that the expiration date displayed has not passed.
If the database has expired, then remove and replace the aviation database card as described in the
following section, and see Section 1.7.1.
