What is the ambient temperature range for ground operation in degrees Celsius?

• A. -30 to 40
• B. -23 to 43
• C. -15 to 45
• D. -10 to 50

Answer: (B)

The ambient temperature range for ground operations typically falls between -23 to 43 degrees Celsius. This range is designed to ensure safe and efficient operation of aircraft systems. Temperatures below -23 degrees can pose challenges such as fuel viscosity issues and inadequate performance of de-icing systems, while temperatures above 43 degrees can lead to increased risks of overheating and operational strains on the aircraft systems.

Choosing this specific range ensures compliance with safety protocols, preventing potential mechanical failures and allowing for optimized performance in various weather conditions. Moreover, it aligns with industry standards for ground operations, providing a broad range that accommodates numerous environmental factors encountered at various operating locations. This ensures that the aircraft is suitable for operation in both extreme cold and warm conditions while maintaining safety and reliability.
