What is the voltage of the auxiliary battery located in the left avionics compartment?

The voltage of the auxiliary battery located in the left avionics compartment is 24 VDC. This specification is essential for ensuring that the electrical systems in the avionics compartment operate correctly and efficiently.

The choice of 24 VDC for the auxiliary battery is typical in aviation, as it provides a good balance between weight and power requirements for the equipment in that compartment. Using 24 VDC helps to reduce the current for a given power requirement, thereby minimizing conductor sizes and improving the overall efficiency of the electrical system in the aircraft. Additionally, this voltage level is generally compatible with many avionics systems and enables the effective functioning of communication and navigation equipment without the risk of overloading or damaging sensitive electronics.

In contrast, options such as 12 VDC would be inadequate for the power needs of most avionics systems, while higher voltages like 32 VDC and 42 VDC could pose risks of damage or operational inefficiencies.
