AFS AP Questions

[Flickroll]

I am doing some preliminary bench testing of a new system with an AFS AP and a G430W. I have an external toggle switch to be able to switch ARINC to the AP from either the AFS unit or directly from the 430 (per the AFS ARINC wiring diagram). I do not yet have the AFS EFIS connected.

With the system on, and the 430 with a position fix, the GPS asterisk is blinking - so far so good!

If I press the EFIS button, I get 'EXT LS' on the display with the external toggle switch in the '430' position. What does that mean? If I put the external toggle in the AFS position, 'EXT LS' goes away, and I go to the 'normal' AP screen (Bank angle, etc.). Is this correct?

Is there a way to test ARINC communication from the 430 to the AP without the EFIS connected?

I am not getting 'GPSS' displayed, even though I have an active waypoint on the 430. Is this OK (probably so since there's no EFIS connected)?

Thanks

So far so good. Everything is working as it should. The EXT LS just means external lateral steering. The ARINC communication is working correctly. When you switch to the EFIS position, the AP goes back to stand alone mode.

Hope this helps!
