Electrical Load Analysis - Garmin G5 Installation Manual

3.4.10 Audio Interference
This STC installation does not interface to audio signals. Attention to harness installation and routing as
specified in Section 3.4.6 should be considered for Audio interference mitigation.

3.5 Electrical Load Analysis

If the current draw of the G5 unit is less than the removed equipment, then the aircraft's electrical load
capacity can be shown to be adequate by analysis. If it is determined the modification results in an
increase in electrical load, then it must be verified the electrical generation and reserve battery capacity
remain adequate to support electrical loads essential to safe flight and landing of the aircraft.
3.5.1 Aircraft with Existing Electrical Load Analysis
If there is an existing electrical load analysis for the aircraft, it must be updated to reflect the
modification. It must show the electrical system has adequate capacity to supply power to the modified
systems in all expected conditions. Refer to the aircraft manufacturer's documentation for guidance on
revising and maintaining the electrical load analysis.
3.5.2 Aircraft without Existing Electrical Load Analysis
Prior to undertaking a complete electrical load analysis, the net change to the electrical load resulting
from the G5 installation should be determined. See Table 3-6 for a sample calculation. The results of this
analysis will be used to determine how to proceed further.
