What does a standard aircraft altimeter measure?
Temperature
Atmospheric pressure
Airspeed
Lift force
Answer explanation
A standard aircraft altimeter measures atmospheric pressure. It uses changes in pressure to determine altitude, as pressure decreases with an increase in altitude.

How does the altitude reading on an aneroid barometer altimeter change as an aircraft climbs?
Increases as atmospheric pressure decreases
Increases as atmospheric pressure increases
Decreases as temperature increases
Stays the same unless manually adjusted
Answer explanation
As an aircraft climbs, atmospheric pressure decreases. An aneroid barometer altimeter measures this pressure change, causing the altitude reading to increase. Thus, the correct answer is that altitude increases as atmospheric pressure decreases.

What principle is used to determine airspeed in a Pitot-static system?
Newton’s Third Law
Bernoulli’s Principle
Archimedes’ Principle
Pascal’s Law
Answer explanation
Bernoulli’s Principle explains how the pressure difference created by varying airspeed in a Pitot-static system allows for the measurement of airspeed. It relates the speed of fluid flow to its pressure.

What is the likely result if a Pitot tube becomes completely blocked?
The altimeter will give false readings
The airspeed indicator will freeze at its last reading
The aircraft will lose lift
The static port will malfunction
Answer explanation
If a Pitot tube is completely blocked, the airspeed indicator will not receive any dynamic pressure changes and will freeze at its last reading, leading to inaccurate airspeed information.

What happens if the static port is blocked while the Pitot tube remains clear?
The altimeter reads normally, but airspeed readings are incorrect
Both the altimeter and airspeed indicator stop working
The airspeed indicator shows incorrect readings based on altitude changes
The airspeed indicator functions normally
Answer explanation
When the static port is blocked, the airspeed indicator will show incorrect readings because it relies on static pressure to measure airspeed. The readings will vary with altitude changes, leading to inaccuracies.

Describe the function of an aneroid barometer altimeter and how it determines altitude.
Evaluate responses using AI:
OFF
Answer explanation
An aneroid barometer altimeter measures atmospheric pressure to determine altitude. As altitude increases, pressure decreases; the altimeter calibrates this change to provide an accurate altitude reading.

List two sources of error that may affect the accuracy of an altimeter and explain how they impact altitude readings.
Evaluate responses using AI:
OFF
Answer explanation
Two sources of error for altimeters are temperature variations and atmospheric pressure changes. Temperature affects air density, leading to inaccurate altitude readings, while pressure changes can cause the altimeter to misinterpret altitude, resulting in errors.
