What is the approximate holding fuel consumption for Operating Conditions O-1?

The correct answer reflects the estimated holding fuel consumption under Operating Conditions O-1, which is critical for flight planning and safety. In this operating condition, airlines and dispatchers rely on established fuel consumption rates to ensure enough reserve fuel is available for holding patterns, which may be required due to air traffic delays or other factors.

Understanding the precise fuel consumption figure, such as 2,850 lbs in this scenario, allows flight crews to plan effectively, ensuring they have sufficient fuel to complete the flight safely while also taking into account any necessary holding patterns before landing. This value is derived from industry standards and reflects average performance metrics for many aircraft types under typical conditions.

When making fuel decisions, it's important to know how these values can vary depending on factors like aircraft type, weight, and environmental conditions, but this case provides a standardized estimate that can guide dispatchers in their calculations. This knowledge is crucial in ensuring compliance with safety regulations and operational readiness.
