Which of the following is NOT a function of the Boost Pumps?

The correct answer highlights the function that does not pertain to Boost Pumps, which is fuel monitoring. Boost Pumps primarily serve to ensure a consistent and adequate fuel supply to the engine. They help with fuel crossfeeding, providing the necessary fuel flow during engine starts, and act as a backup to primary jet pumps in certain scenarios where fuel flow may be disrupted.

Fuel monitoring, on the other hand, is primarily the function of systems designed to measure and indicate the quantity and quality of fuel rather than the movement or delivery of it. This task is typically handled by fuel quantity indicators and other monitoring systems, which track fuel levels and provide data to the flight crew. Understanding the distinctions between these functions clarifies the role of Boost Pumps within the broader fuel management system.
