* 400/500 series units must use Pilot Guide Addendum 190-00140-13 Revision D, or later.
400/500 series units may be connected to a GDL 69A. The 400/500 series units do not have audio
control capabilities, but the aircraft may be provisioned with a GDL 69A and wiring for future
400/500 series upgrade that will provide audio control and display.
1.5 Audio Entertainment Installation Limitations
The GDL 69A XM Satellite Radio audio entertainment may be installed to all passenger locations for all
aircraft on the STC Approved Model List (AML). XM audio entertainment to crew locations depends on
aircraft installation, which must meet requirements of 14 CFR §23.1431(e).
For purpose of this STC, 14 CFR §23.1431(e) requires that each pilot station must be able to hear the
aircraft’s stall warning horn with the entertainment system audio set to the maximum pilot controllable
setting. This also applies to aircraft with a gear extension warning horn. Aircraft which have electric
stall/gear warning may utilize the GDL 69A audio suppression input to turn off the music during an
event. For these installations, the XM audio may be provided to the crew locations.
For aircraft installations with non-electric stall/gear warning horns, this STC does not provide data for
installation of audio entertainment to crew locations. The GDL 69A audio entertainment may not be
wired to crew locations without a separate evaluation that is beyond the scope of this STC. It is possible
for installers to seek evaluation and approval of an alternate installation by means of the field approval
process. Each installation or aircraft type must be evaluated for compliance with 14 CFR §23.1431(e).
This evaluation may determine that the required horns can be heard satisfactorily without disabling the
GDL 69A audio entertainment to the crew.
