What is the minimum amount of usable fuel in the mains?

The minimum amount of usable fuel in the mains for the SkyWest CRJ 200 is 4,760 lbs. This figure is critical for ensuring that the aircraft maintains proper fuel levels for safe operation during flight. Adequate fuel reserves are crucial for several reasons, including maintaining engine performance, accommodating unforeseen circumstances such as holding patterns or diversions, and ensuring compliance with regulations and safety standards.

This specific amount is derived from the aircraft's design and operational guidelines, which take into account various factors such as fuel burn rates, duration of flight, and reserve requirements. By establishing a minimum usable fuel level, pilots can better manage inflight fuel consumption and maintain overall aircraft safety. Understanding this limitation helps crew members make informed decisions regarding fuel load calculations prior to departure and ensures that they are equipped to handle normal and emergency situations effectively during flight.
