Presurización y Altitud en Aeronaves

What are two main reasons why pilots prefer to fly at higher altitudes?

• To consume more fuel and experience greater turbulence.

• To avoid air traffic and enjoy panoramic views.

• For greater fuel efficiency and to avoid weather hazards and turbulence.

• To reduce airspeed and increase flight time.

What are the two main ways to safely and legally ascend to high altitudes?

• Provide supplemental oxygen to the crew and passengers, or fly a pressurized aircraft.

• Increase airspeed and reduce the weight of the aircraft.

• Fly only during the day and avoid clouds.

• Use an advanced navigation system and constantly communicate with air traffic control.

In a piston-powered airplane, where is the air pumped from to pressurize the cabin?

• From the auxiliary air conditioning system.

• From the engine's turbocharger.

• Directly from the outside ambient air.

• From the engine's compressor section (bleed air).

What is the main function of the primary outflow valve in a pressurized aircraft?

• Regulate the cabin temperature.

• Maintain the maximum allowable differential pressure in the aircraft.

• Provide emergency oxygen.

• Control the fuel flow to the engine.

What is meant by "differential pressure" in the context of aircraft pressurization?

• The difference in pressure between the cabin and the baggage compartment.

• The difference in pressure between the cabin and the ambient atmospheric pressure.

• The maximum pressure that the aircraft structure can withstand.

• The pressure of the air supplied by the turbocharger.

If a plane flies at 24,000 feet and the ambient pressure is 5.7 psi, what would be the cabin altitude if the maximum differential pressure is 5.5 psi?

• 6,000 feet

• 7,800 feet

• 8,000 feet

• 10,000 feet

For a planned flight at a final cruising altitude, how should the pilot adjust the cabin altitude selector before takeoff?

• To the final cruising altitude.

• 500 feet below the final cruising altitude.

• 500 feet above the final cruising altitude.

• To the desired cabin altitude.

What is the main function of the cabin altitude controller in a pressurization system?

• Adjust the maximum differential pressure.

• Regulate the cabin altitude.

• Adjust the rate of ascent or descent of the cabin.

• Control the cabin temperature.

What are the three main pressurization instruments provided to pilots to monitor the status of the system?

• Cabin altitude, cabin rate of climb/descent, and differential pressure.

• Cabin altitude, cabin temperature, and humidity.

• Ambient pressure, cabin pressure, and flight altitude.

• Airspeed, cabin altitude, and fuel pressure.

If the cabin air leak rate exceeds the purge air supply, what main consequence could occur?

• The cabin will depressurize rapidly.

• The aircraft would not be able to maintain the maximum differential pressure.

• The cabin temperature would increase.

• The pressurization system would shut down automatically.
