Respuesta :
ariations in temperature can affect the altimeter readings due to changes in air density. Altimeters measure altitude based on atmospheric pressure, which decreases with altitude. However, temperature also affects air density, and this can lead to discrepancies in altimeter readings.
Here's how temperature variations impact altimeter readings:
Temperature and Air Density: Warmer air is less dense than colder air. As temperature increases, air molecules spread out, reducing air density. Conversely, colder air is denser because molecules are closer together.
Pressure and Altitude Relationship: Altimeters rely on atmospheric pressure to determine altitude. As you ascend in altitude, atmospheric pressure decreases. However, if the air temperature is significantly different from standard atmospheric conditions (15°C or 59°F at sea level), the altimeter reading may not accurately reflect the true altitude.
Non-Standard Atmosphere Corrections: To compensate for non-standard atmospheric conditions, pilots often adjust altimeter readings using standard atmosphere tables or by setting the altimeter to the current local altimeter setting provided by air traffic control. This adjustment helps align the altimeter reading with the actual altitude above mean sea level.
Temperature Inversion Effects: In certain weather conditions, such as temperature inversions, the normal decrease in temperature with altitude is inverted, causing warmer air to be found at higher altitudes than colder air. This can lead to abnormal altimeter readings and is something pilots need to be aware of, especially during instrument flight.Answer:
