TESTING QUESTIONS

   I've been back and forth to my radio shop too many times to count.  The squawk list just never seems to get shorter.  Mark off two items, add two more, etc.
Anyway, he wants me to test the terrain warning audio.  Is there any way to test this connection to the audio panel while on the ground?  The user manual says,:

Adjusting Traffic Volume Plays Chime
As the volume bar for the traffic alerts is adjusted,
the IFD will play a double chime that represents the
new volume level selected.

Would this apply to terrain alerts, too? (I don't have traffic alerts yet).  Would this be a matter of adjusting the volume for "aural alerts" and listening for the chime in the headset?  I have never heard a terrain warning yet, but I'd like to know that it's hooked up.  I guess I could do a low pass out in the country somewhere and see if it warns me, but I'd rather just check this on the ground somewhere.

He didn't have the ground/air wire hooked up to the AXP-340 originally, and wants me to test that.  I think it should show GND on the ground, and automatically switch to ALT upon takeoff, right?  That one should be easy.

Thanks in advance for helpful replies,

Paul B.

	Paul, Not quite yet. Release 10.1.0.0 adds the capability to play the alert audio in your headset as you adjust the volume but that's still a few weeks from cert. The traffic adjust audio does not accomplish what you're looking for. As for the air/ground transition with the AXP340, yes, if properly hooked up to the 540 pin, you should see the automatic switch to ALT on takeoff and back to GND on landing.

	GND/AIR transition works great! Terrain aural alerts work great! (had to dive at the ground! LOL) Another TESTING QUESTION: Is there a way to tell if the pressure altitude from the AXP-340 is being received by the IFD-540???

	Go the AUX\|Calculators page ... Values in green are received data. If in white, there is no accepted data. * Orest Edited by oskrypuch - 31 Mar 2015 at 10:27pm

	AviJake writes that the audio alert in the headset is in 10.1. How did you hear the audio alerts without 10.1? Guess I have to go back to the shop (again) to get the xpdr wired properly - my AXP-340 does not auto switch gnd/air. Sure wish there were ways the installer could test all this stuff before turning it loose to the pilot/owner!

	Yes, there are audio alerts with 10.0.0.3, including the Descend Now gong. * Orest

	AXP340 Air/Gnd can be tested at power up if connected to 540 per ADSB STC. My XPNDR posts "alt" for 34sec till the 540 finishes initializing then switches to "Gnd" Edited by roltman - 08 Jun 2015 at 10:08pm
