Day 6 Progress Check Flashcards
What is the primary role of engine instruments in an aircraft?
Monitor engine parameters like quantity, pressure, speed, and temperature
Which system feature in modern instrument panels reduces wiring and increases efficiency?
Digital data buses
What factor influences the accuracy of an analog altimeter?
Weather conditions, temperature, and installation errors
What is the main function of a pressure switch in an aircraft instrument system?
It triggers actions based on reaching a pressure threshold.
What is the role of an air data computer (ADC) in a modern aircraft system?
It converts air pressures into digital values and compensates for accurate instrument
How do solid-state sensors in pressure measuring instruments operate?
They convert pressure changes into electrical signals using piezoelectric or semiconductor
Which instruments are connected to the pitot-static system?
Altimeter, airspeed indicator, and vertical speed indicator
What is the purpose of a Machmeter in high-performance aircraft?
It measures the aircraftâ s speed as a fraction of the speed of sound.
What type of pressure is compared to a total vacuum?
Absolute pressure
What do pitot-static systems primarily measure?
Air pressure for flight instruments like airspeed, altitude, and vertical speed
What are Bourdon tubes commonly used for in aviation instruments?
To measure high pressures by straightening out under pressure
Which instrument helps a pilot monitor the rate of climb or descent?
Vertical Speed Indicator (VSI)
In an aircraft with multiple engines, how is engine information commonly displayed?
A single gauge with multiple pointers displaying information for all engines
How does the Kollsman window on an altimeter function?
It adjusts for barometric pressure, allowing accurate altitude readings.
What is the significance of the Engine Pressure Ratio (EPR) for turbine engines?
It compares exhaust pressure to inlet pressure to measure engine performance.
