SET 2 AMT 11-03 FINALS LONG QUIZ

What environmental systems do aircraft use to handle extreme temperature and pressure conditions during high-altitude flights?

• Air conditioning only
• Pressurization only
• Both pressurization and air conditioning
• None of the above

Define "Cabin Altitude" in an aircraft.

• The altitude above sea level
• The altitude of the aircraft's cockpit
• The effective altitude inside the aircraft's cabin
• The altitude at which the aircraft maintains constant speed

What does "Cabin Differential Pressure" refer to?

• The difference between cabin altitude and actual altitude
• The difference between air pressure inside and outside the cabin
• The rate of change of air pressure inside the cabin
• The pressure difference between the troposphere and stratosphere

Which term represents the rate of change of air pressure inside the cabin?

• Cabin altitude
• Cabin differential pressure
• Cabin rate of climb
• Reciprocating engine

What are the two main sources of air for pressurizing reciprocating engine aircraft?

• Turbochargers and jet pumps
• Superchargers and turbochargers
• Bleed air and recirculation fans
• Air cycle system and turbocompressor

In turbine engine aircraft, what is used for cabin pressurization, and how much cabin air is typically recirculated?

• Ambient air; 25%
• Bleed air; 50%
• Jet pump flow multiplier; 75%
• Air cycle system; 100%

What method is commonly used in turbine-powered aircraft for controlling pressurization and air temperature?

• Jet pump flow multiplier
• Air cycle system
• Recirculation fans
• Superchargers

What does the control of cabin pressure in an aircraft involve?

• Adjusting engine performance
• Maintaining a comfortable and safe environment
• Managing fuel efficiency
• Controlling external atmospheric pressure

What are the two modes of aircraft cabin pressurization, and when does the system switch between them?

• Constant and variable; during descent
• Isobaric and constant differential; during ascent
• Isobaric and constant differential; during descent
• Variable and fixed; during cruising

How is the rate of change of cabin pressure, known as cabin rate of climb or descent, controlled?

• Manually by passengers
• Automatically or manually by the flight crew
• Automatically by the ground control
• Manually by the cabin crew
