Questions and Answers

What’s first thing that happens in the process of creating thrust in a turbofan engine?

  • Combustion
  • Compression
  • The large fan will suck in air (correct)
  • All of the above
  • Which one is in the correct order?

  • Suction,compression,combustion and exhaust (correct)
  • Non of the above
  • combustion,exhaust,compression and suction
  • All of the above
  • The incoming air is captured by the engine inlet. Some of the incoming air passes through the fan and continues on into the core compressor and then the burner, where it is mixed with fuel and combustion occurs.which engine works like this?

    a rotating gyro to display the current compass rose direction (otherwise known as the heading) that the aircraft is flying. Using a 360-degree compass card with north as zero or “N,” the HI shows headings in 5-degree increments with every 30 degrees enumerated. To reduce crowding, the last “zero” of the heading is omitted—”3” is 30 degrees, “12” is 120, etc

    uses internal pressure differential to provide a visual indication of how fast the aircraft is climbing or descending. A diaphragm with chambers connected to the static port expands or rate of climb or descent in hundreds of feet per minute (fpm). A hole in the diaphragm releases the pressure change to return to zero rate when no change is occurring

    Study Notes

    Turbofan Engine Thrust Creation

    • Thrust begins with capturing incoming air through the engine inlet.
    • Air flows through the fan, entering the core compressor, and continues to the burner for combustion with fuel.
    • This process is characteristic of turbofan engines.

    Functions of Bleed Air System

    • Bleed air systems utilize compressed air extracted from the engine’s compressor stages.
    • Common functions include cabin pressurization, engine start assist, and environmental control.
    • One function not associated with the bleed air system might be fuel management.

    Airspeed Indicator

    • Measures the aircraft's speed relative to surrounding air.
    • Displays speed in knots or miles per hour depending on the system design.

    Attitude Indicator

    • Utilizes a canted internal gyro to display the aircraft's orientation relative to the horizon.
    • Shows initial roll rate and stabilized turn rate; features an aircraft silhouette for visual reference.

    Altimeter

    • Uses barometric pressure from the static port to indicate the aircraft's altitude in feet above mean sea level (MSL).
    • Essential for maintaining flight levels and ensuring separation from terrain and other aircraft.

    Heading Indicator (HI)

    • Incorporates a rotating gyro to display the aircraft’s current heading using a 360-degree compass card.
    • Displays headings in 5-degree increments; omits the last “zero” for simplicity (e.g., “3” represents 30 degrees).

    Vertical Speed Indicator (VSI)

    • Uses internal pressure differential to indicate the rate of climb or descent in hundreds of feet per minute (fpm).
    • Features a diaphragm connected to the static port, returning to zero rate when there is no altitude change.

    Ground Proximity Warning System (GPWS)

    • GPWS stands for Ground Proximity Warning System.
    • It warns pilots of impending ground collisions, alerting them to terrain proximity.
    • When a GPWS alert is activated, pilots should execute immediate corrective actions.

    Fly-By-Wire Systems

    • Employ computer technology to process pilot or autopilot commands, directing flight control surfaces.
    • Inherent protections help prevent pilot-induced oscillations and other unsafe flight scenarios.
    • Benefits of fly-by-wire include reduced weight, enhanced safety, and improved maneuverability.
