When operated by the generators, how many VDC (Volts DC) does the electrical power supply system supply to the airborne electrical system?

Explanation:
Airborne electrical systems run on a regulated DC bus. When the generators are online, they feed the system and keep the bus voltage at a nominal level around 28.5 volts. This value is chosen because it provides enough voltage to power avionics and loads reliably while leaving room for small fluctuations under load. So the system delivers about 28.5 VDC when the generators are supplying power. The other numbers don’t fit this regulated, generator-powered setup: 24.0 V is typical for a lower or battery-related level, 26.0 V would be below the regulated target, and 30.0 V would be too high for standard avionics protections.
