Frequently Asked Questions (FAQs)
1. What do altimeters measure?
Altimeter on the Matterhorn. An altimeter is a device that measures altitude—a location's distance above sea level. Most altimeters are barometric, meaning they measure altitude by calculating the location's air pressure.
2. What are altimeters in aviation?
The altimeter measures the height of an aircraft above a fixed level. The instrument senses this by taking the ambient air pressure from the static port. That air is plumbed through the back of the panel and into the back case of the altimeter. Inside the altimeter is a sealed disc called an aneroid, or bellows.
3. How accurate are altimeters?
With proper calibration, the barometric altimeter of an outdoor watch or handheld will report elevation readings ranging from -2,000 to 30,000 feet with an accuracy of +/-50 feet. Elevation values greater than 30,000 feet can be generated, but may not be accurate due to environmental factors.
4. How do pressure altimeters work?
It works by measuring air pressure, utilising the fact that the air pressure of the atmosphere decreases by approximately 1 millibar for each 10 metres in height. The pressure measured is static pressure and so is independent of the airspeed of the aeroplane.
