What is the primary purpose of an altimeter in aviation?
✔✔The primary purpose of an altimeter is to measure the altitude of an aircraft above a
reference level, usually sea level.
Explain the function of a VSI (Vertical Speed Indicator).
✔✔The VSI indicates whether an aircraft is climbing or descending and at what rate, providing
essential information for maintaining altitude.
What is the significance of the pitot-static system?
✔✔The pitot-static system is crucial for measuring airspeed and altitude by using the difference
between static and dynamic air pressure.
How does a gyroscope work in aircraft instruments?
✔✔A gyroscope maintains orientation and provides critical information about the aircraft's
attitude and heading.
1
,What does a DME (Distance Measuring Equipment) indicate?
✔✔DME measures the distance between an aircraft and a ground-based DME station, helping
pilots determine their position relative to navigational aids.
What are the differences between primary and secondary flight instruments?
✔✔Primary flight instruments provide direct and essential data for controlling the aircraft, while
secondary instruments offer additional information that supports flight operations.
Describe the function of a magnetic compass in aviation.
✔✔A magnetic compass indicates the aircraft's heading relative to magnetic north, essential for
navigation.
What is the purpose of a turn coordinator?
✔✔The turn coordinator provides information about the rate of turn and helps pilots maintain a
standard rate of turn during flight.
How do you interpret a fuel flow gauge?
✔✔A fuel flow gauge indicates the rate at which fuel is being consumed by the engine, helping
pilots manage fuel usage effectively.
2
,What is the role of an engine pressure ratio (EPR) gauge?
✔✔The EPR gauge measures the pressure ratio between the inlet and outlet of a jet engine,
providing information about engine performance.
What is the function of an attitude indicator in an aircraft?
✔✔The attitude indicator shows the aircraft's orientation relative to the horizon, indicating
whether the wings are level, climbing, or descending.
Explain the purpose of a heading indicator.
✔✔The heading indicator displays the aircraft's current heading, allowing pilots to maintain a
specific course during flight.
What does a tachometer measure in an aircraft?
✔✔A tachometer measures the rotational speed of the engine's crankshaft, providing information
about engine performance and efficiency.
How does a fuel gauge work?
3
, ✔✔A fuel gauge uses a float mechanism or electronic sensors to indicate the amount of fuel
remaining in the tanks, helping pilots manage fuel levels.
What is the role of a landing gear indicator?
✔✔The landing gear indicator shows the position of the landing gear, confirming whether it is
extended or retracted.
Describe the function of a clock in aviation instruments.
✔✔A clock provides critical timing information for navigation, flight planning, and adherence to
air traffic control instructions.
What is the purpose of an airspeed indicator?
✔✔An airspeed indicator measures the aircraft's speed through the air, essential for safe
operation during different phases of flight.
How does an ADF (Automatic Direction Finder) work?
✔✔The ADF determines the direction to a ground-based radio beacon, assisting in navigation by
providing real-time bearing information.
