Day 5 Progress Check Flashcards
Which type of pressure is measured against a total vacuum, and is commonly used in aircraft systems?
Absolute pressure
Which flight instrument uses both static and dynamic air pressure to provide readings?
Airspeed indicator
What factor primarily affects the accuracy of a pressure altimeter?
Weather conditions, temperature, and installation errors.
How do solid-state sensors in pressure-measuring instruments work?
By converting pressure changes into electrical signals using piezoelectric or semiconductor chips.
How do Air Data Computers (ADC) improve the function of pitot-static systems?
They convert air pressures into digital values and perform compensation for accurate readings.
Why is it important to understand the operation of the Kollsman window on an altimeter?
It adjusts for barometric pressure, allowing accurate altitude measurements.
In what scenario would you use differential pressure instruments?
To compare engine inlet and exhaust pressures in turbine engines.
Why is a Machmeter essential for high-performance aircraft?
It measures the aircraftâ s speed as a fraction of the speed of sound, ensuring safe high-speed operations.
In a multi-engine aircraft, how is engine information commonly displayed?
A single gauge with multiple pointers displaying information for all engines.
What is the major advantage of digital data buses in modern instrument systems?
They reduce wiring, weight, and increase system reliability.
Which of the following best describes the primary evolution of aircraft instruments from early aviation to modern systems?
A transition from individual analog instruments to integrated digital systems with flat-panel displays.
Which system component in pitot-static systems is responsible for capturing impact air pressure?
Pitot tubes
What is a key responsibility of technicians regarding modern aircraft instrument systems?
Understanding both analog and digital systems, including troubleshooting and maintaining them.
What is the function of the altimeter and airspeed indicator?
They monitor flight, altitude and speed.
What is the purpose of an instantaneous vertical speed indicator (IVSI)?
It reduces the lag in the display of rate of climb or descent compared to a standard VSI.
