Day 7 Progress Check Flashcards
Why is it important to maintain a positive head of fuel at the inlet of a centrifugal pump?
To prevent the pump from cavitating and overheating
What is the primary reason for installing fire sleeves over certain fuel lines?
To protect against abrasion and fire
What is a key advantage of using bladder fuel tanks over rigid fuel tanks?
Easier installation through small openings
What role does a fuel heater play in turbine-powered aircraft?
Preventing ice formation in the fuel system
Which type of fuel pump is most commonly used as an auxiliary pump on large aircraft?
Centrifugal boost pump
Why might a solenoid-operated fuel valve be preferred over a hand-operated valve in certain applications?
Faster response time and remote operation
Which type of fuel tank is most likely to be found in modern high-performance aircraft?
Integral fuel tank
How do capacitance-type fuel quantity indicators work?
By measuring the capacitance changes in fuel probes
What is the function of a gascolator in an aircraft fuel system?
To filter and collect sediment and water from fuel
How do baffle check valves contribute to the safety of integral fuel tanks?
By preventing fuel from moving outboard
What is the primary function of a sump in an aircraft fuel tank?
To settle contaminants and water for removal
How does a centrifugal boost pump ensure positive pressure in the fuel system?
By drawing fuel into the center and expelling it outward
What does a differential pressure indicator in a fuel filter assembly signal?
Blockage in the filter
Why are fuel quantity indicators critical for aircraft operation?
To provide accurate fuel management and ensure safety
Why is it important to use only approved replacement parts for aircraft fuel lines and fittings?
To ensure compatibility and safety
