What affects the accuracy of altimeters and altitude during flight?

• A. Changes in weather conditions
• B. Both of the answers are correct
• C. Changes in aircraft configuration
• D. Changes in altitude only

Answer: (B)

The accuracy of altimeters and altitude during flight is influenced by several factors, including changes in weather conditions and aircraft configuration. Changes in atmospheric pressure due to weather fluctuations can significantly affect altimeter readings. For instance, if the barometric pressure decreases, the altimeter may indicate a higher altitude than the actual altitude, which can lead to dangerous situations during flight. Additionally, changes in aircraft configuration—such as variations due to fuel load, wing flaps, and landing gear—can impact how an aircraft experiences lift and drag, affecting its true altitude. Since both weather conditions and aircraft configuration can independently and collectively influence altitude readings, the answer indicating both factors is not only accurate but necessary for a comprehensive understanding of what affects altimeter readings during flight.
