Day 6 Progress Check Flashcards
Why is it crucial for a fuel system to provide an uninterrupted flow of contaminant-free fuel?
To maintain proper engine and auxiliary power unit (APU) functioning.
What are the consequences of improper fuel storage refilling or recharging?
Potential contamination of stored fuel.
Why is it critical to use the correct type of aviation fuel for each engine?
To prevent detonation and ensure proper engine performance.
Why must the fuel system be protected against lightning strikes?
To prevent the ignition of fuel within the system.
What is the importance of fuel venting requirements in turbine engine powered airplanes?
To ensure continued operation even with water in the fuel.
What is the purpose of fuel system independence?
To prevent the loss of fuel storage or supply due to the failure of one component.
How can vapor lock be prevented in an aircraft fuel system?
By using boost pumps to pressurize the fuel.
Why is it important to maintain fuel purity, and what common issue compromises it?
To prevent engine corrosion; compromised by water contamination.
How does detonation affect engine performance and longevity?
It causes rapid, uncontrolled explosions that can damage the engine.
What steps can be taken to prevent microbial contamination in jet fuel?
Using biocides and minimizing water presence in fuel tanks.
What is the main cause of carburetor icing, and how can it be mitigated?
Presence of moisture; mitigated by using carburetor heating.
What are the dangers of using aromatic fuels in modern aviation engines?
They require special hoses and seals not commonly used today.
What is the significance of octane and performance number ratings in aviation fuel?
They indicate the fuel’s resistance to detonation.
How must a fuel system be designed to handle variations in fuel loads during maneuvers?
By preventing shifts in weight from negatively affecting aircraft control.
What does 14 CFR part 23, section 23.2430 specifically address regarding fuel systems?
The airworthiness standards for fuel systems in normal category airplanes.
