pair Bluetooth™ audio sources. This enables the distribution of audio to ICS positions when using a
compatible iOS or Android™ device. The GMA 35c supports up to ten stored devices and one active
Bluetooth device. The GMA 35 is mounted in a notch behind the GTN 7XX to free up mounting space in
the flight deck instrument panel.
If optional HTAWS function is enabled on the GTN, HTAWS terrain caution/warning indicator and HTAWS
status annunciation are required, unless the rotorcraft is equipped with a GDU 620. These annunciators
serve as the visual indication of a terrain/obstacle caution or warning alert, HTAWS failure and HTAWS
mode status.
The Flight Stream 510 is a wireless-enabled data card that is inserted into the GTN data card slot to allow
wireless database synchronization with personal electronic devices (PEDs). Synchronized information is
then disseminated to various LRUs through their existing GTN interface connections.

2.5 Periodic Maintenance
The GTN and GMA 35 are designed to detect internal failures. A thorough self-test is executed
automatically upon application of power to the units, and built-in tests (BIT) are continuously executed.
Detected errors are indicated as failure annunciations, system messages, or a combination of the two.
Operation of the GTN 6XX/7XX and GMA 35 is not permitted unless the inspections described in this
section have been completed within time intervals prescribed in Table 1. All antennas connected to the
GTN should be maintained in accordance with maintenance and inspection data appropriate for the
antenna installation.
