What is the altitude limit for the main generator's output to remain at 30 KVA?

• A. 30,000 ft
• B. 32,000 ft
• C. 35,000 ft
• D. 37,000 ft

Answer: (C)

The correct altitude limit for the main generator's output to remain at 30 KVA in the CRJ 200 is 35,000 feet. At altitudes above this limit, the performance of the generator begins to degrade, which can lead to insufficient power output to meet aircraft systems' needs. Understanding this limitation is crucial for maintaining adequate electrical power for avionics and other critical systems, ensuring safe operation and flight management.

Generators have performance parameters that vary with altitude, often due to decreased air density affecting their cooling capabilities and electrical output efficiency. Hence, it is essential for pilots and flight engineers to be aware of this critical altitude limitation when planning flight operations and ensuring all systems receive necessary power throughout the flight.
