What is the maximum usable fuel quantity per tank for the ERJ 170/175?

The maximum usable fuel quantity per tank for the ERJ 170/175 is 10,393 pounds. This figure is critical as it directly influences the aircraft's weight and balance calculations, fuel management during flight, and overall operational capabilities.

Understanding the maximum fuel capacity is vital for pilots to ensure the aircraft remains within its weight limits for takeoff and landing, as exceeding these limits can impact performance, safety, and compliance with aviation regulations. In the case of the ERJ 170/175, the engineers have designed the fuel system to optimize the fuel consumed while considering aspects such as tank structure, fuel quality, and operational efficiency.

Recognizing this limitation helps flight crews manage fuel loads effectively for each flight, ensuring that they can operate within the aircraft's certified performance parameters. This knowledge also aids in planning for alternate airports and potential delays, allowing for safe and efficient operation throughout the flight.
