Electric Vertical Takeoff and Landing (eVTOL) aircraft are electrically powered vehicles capable of vertical takeoff and landing like helicopters, while offering higher energy efficiency, lower noise levels, and reduced emissions. Regarded as a crucial component of future urban air mobility (UAM), these aircraft demonstrate significant potential in alleviating ground traffic congestion and providing rapid intercity or intra-city transportation.

The widespread application of low-altitude aircraft in agriculture, logistics, mapping, and other fields has made safety concerns increasingly prominent, with electrical performance testing serving as the core component ensuring their safe operation. As the energy source, the safety performance of the battery system directly impacts flight safety, as battery failures may lead to severe consequences such as aircraft crashes, collisions with buildings, or injuries to people. Electrical performance testing can simulate various phenomena that may cause power supply anomalies during steady-state operation and verify the performance of the EUT under such conditions, including power interruptions due to power source switching, voltage surges, and transient voltages that may occur during engine startup.
The electrical performance testing in the RTCA/DO-160G standard primarily involves verifying the electrical characteristics of equipment under conditions such as power input and voltage spikes, ensuring that airborne equipment operates reliably in complex electrical environments. It focuses on evaluating the equipment's immunity to power disturbances and voltage spikes on power lines, as well as its own electrical safety, to ensure continued normal operation under extreme environmental conditions.
