Day 11 Progress Check Flashcards
In boosted brake systems, how is pilot-applied pressure augmented during heavy braking?
By utilizing aircraft hydraulic pressure to assist with braking force
How do floating disc brakes function in an aircraft braking system?
The disc is keyed to the wheel and moves laterally, allowing even pad wear
What is the purpose of a brake debooster in an aircraft hydraulic system?
To reduce hydraulic pressure from the control valve to match the brake assembly’s requirements
Which component in a brake debooster system helps prevent fluid loss in the event of a downstream rupture?
The brake deboosterâ s hydraulic flow stop feature
Which system provides braking power if the primary hydraulic system fails during an emergency?
Emergency brake systems using redundant hydraulic systems or accumulators
What type of aircraft brake system uses master cylinders connected to the rudder pedals to generate hydraulic pressure?
Independent brake systems
What is a key feature of emergency brake systems in large aircraft?
They use shuttle valves and hydraulic fuses to ensure brake operation in case of failure
What is the primary function of aircraft brakes during ground operations?
To slow and stop the aircraft within a reasonable distance and hold it stationary
Why are segmented rotor-disc brakes commonly used in high-performance aircraft?
To dissipate large amounts of heat generated during braking more efficiently
What is the role of self-adjusting pins in floating disc brake systems?
To maintain a consistent braking distance as brake wear occurs
Which type of brake is used on large, heavy aircraft and consists of alternating stators and rotors?
Multiple-disc brakes
How is the parking brake engaged in most aircraft?
By trapping hydraulic fluid in the brake lines using a mechanical ratchet system
Which type of brake is the most commonly used on modern aircraft?
Disc brakes
What is the advantage of carbon brakes over conventional steel brakes?
Carbon brakes are 40% lighter and withstand higher temperatures
What is the function of the brake metering valve in a power brake system?
To control hydraulic fluid pressure based on rudder pedal input
