What is the minimum dispatch fuel required for the ERJ 170/175?

The minimum dispatch fuel required for the ERJ 170/175 is 2,000 lbs. This figure is established based on operational safety protocols which ensure that the aircraft has enough fuel not only for the flight itself but also to account for contingencies such as holding, diversions, and potential unforeseen circumstances that could require extra fuel consumption. By requiring 2,000 lbs of dispatch fuel, it emphasizes the importance of maintaining a safety buffer, thereby enhancing the reliability and safety of the flight operation.

The other options present different fuel amounts that do not meet the specific requirements set forth in the aircraft's operating parameters. Each of those lower values may not sufficiently cover the calculated needs for a safe dispatch and the protections that are necessary for any irregular flight operations, underscoring the importance of adhering to established fuel limitations.
