At what altitude does the generator limit drop from 100% to 95%?

The correct altitude at which the generator limit drops from 100% to 95% is 34,000 feet. This limit adjustment is based on the operational characteristics of the King Air 350's electrical system at higher altitudes, where the engine performance can be affected by a decrease in air density. At altitudes above 34,000 feet, the generators cannot produce the same level of output due to the thinner air and reduced engine efficiency, necessitating a drop in the limit to ensure reliable operation and prevent overload scenarios. Maintaining this limit is crucial for the safety and performance of the aircraft, ensuring that the electrical demands do not exceed the generators' capabilities under these less favorable conditions.
