What are Aircraft Altimeters?
How Do Altimeters Work?
An aircraft altimeter is a key instrument used to measure the altitude of an aircraft above a given datum or reference point. It operates based on the principle that atmospheric pressure decreases with increasing altitude, which provides pilots with accurate altitude readings during flight.
Whether you are an aviation enthusiast or a pilot looking for more information on altimeters, this article will provide you with the knowledge you need. But first things first, let’s get a better understanding of what aircraft altimeters are.
Altimeters work with a sealed aneroid capsule that is connected to a series of gears and levers which amplify the small movements of the capsule. As the aircraft climbs or descends, the capsule expands or contracts, causing the gears and levers to move a pointer on the instrument's face.
The 4 Key Components of Altimeters
Interpreting altimeter readings is a complex task that requires a thorough understanding of various factors. Pilots undergo extensive training to ensure they can accurately interpret altimeter readings and make informed decisions based on the altitude information provided.
Modern altimeters often incorporate additional features, such as digital displays, altitude trend indicators, and altitude alerting systems. These enhancements improve the accuracy and usability of altimeters, providing pilots with even more valuable information during their flights.
The 3 Types of Aircraft Altimeters
When it comes to aircraft altimeters, there are a wide range of options available, each with its own unique features and advantages. Let's dive deeper into the most commonly used types to get a better understanding of their functionality and applications.
An altimeter measures the atmospheric pressure at the aircraft's current location, which is then compared to the known standard pressure at sea level. By calculating the difference between the two pressures, the altimeter determines the corresponding altitude.
The instrument's face is calibrated in units of altitude, such as feet or meters, allowing pilots to easily read their aircraft's altitude, allowing pilots to accurately determine the aircraft's altitude. Once this process is complete, the pilots proceed to interpret the altimeter readings.
How to Interpret Altimeter Readings
Pilots must interpret altimeter readings correctly to ensure safe and accurate altitude navigation. There are a lot of factors that go into these interpretations, pilots must consider:
Regardless of the type of altitude indicator used, pilots rely on this component to keep track of their aircraft's altitude. Once you have understood what altimeters are, their main functions, and the components of these aircraft parts, let’s get into the different types of aircraft altimeters.
The 3 Most Common Altimeter Issues
As technology continues to advance, new types of altimeters are being developed, each offering unique features and capabilities. Once you know which altimeter you need and you have made your purchase, it is also important to take into account that you will need to maintain and troubleshoot it.
The effect of temperature on pressure as the altimeter may indicate a higher altitude than the actual height above sea level.
The variations in reference pressure do to weather systems and geographical locations.
Non-standard atmospheric conditions which can cause discrepancies between the indicated altitude and the actual height above sea level.
Now that we have better understood how altimeters work and how pilots can read them, let’s take a deeper look into their main functions. This will help you better understand why altimeters are so crucial to proper aircraft function.
The 5 Main Functions of Altimeters
Accurate altitude information is essential for pilots to ensure safe navigation, proper separation from other aircraft, and compliance with flight regulations. But these aren’t the only roles they play in proper aircraft function. Aircraft Altimeters can:
Prevent potential hazards and risks in the skies by alerting pilots.
Help comply with airspace regulations.
Aid in maintaining a safe distance from other aircrafts.
Enable pilots to follow designated flight paths and avoid restricted airspace.
Ensure the aircraft maintains the correct altitude during landing and take off.
Now that we understand what altimeters are and why they are so crucial to the proper function of an aircraft, we can delve into the main components of aircraft altimeters to gain a deeper insight.
Aircraft altimeters provide pilots with accurate altitude readings, allowing them to navigate the skies safely and efficiently. They are composed of four components that make these altimeters work. So let’s get a deeper look at these components.
Component of Altimeter | Function of the Component | How it Works |
Pressure Sensor | It detects and measures the atmospheric pressure and converts it into altitude readings, which allows pilots to accurately determine their aircraft's height above sea level. | It consists of a diaphragm that flexes in response to changes in air pressure, which triggers a mechanism that converts the pressure readings into altitude measurements. |
Aneroid Wafer | It is used to determine the aircraft’s altitude by expanding or contracting according to atmospheric pressure. | It is a small, flexible disk made of a sensitive metal material, that is connected to a mechanical linkage system that translates its movement into altitude readings. |
Altitude Indicator | It shows the altitude reading in feet or meters through a mechanical or digital display allowing pilots to monitor the aircraft's altitude. | They consist of a series of gears, levers, and dials that move in response to the movement of the aneroid wafer and provide a reliable altitude reading. |
Digital Altitude Indicators | They offer enhanced accuracy on readings and additional features such as altitude alerts and trend indicators. | These modern displays use electronic sensors and microprocessors to calculate and display altitude readings. |
Type of Altimeter | How They Work | Uses of The Altimeter |
Barometric Altimeters | They rely on changes in atmospheric pressure to provide accurate altitude readings to precisely determine the aircraft's altitude. | They are useful during flight planning and navigation, as they provide pilots with essential altitude information. |
Radar Altimeters | They utilize radio waves to determine the aircraft's altitude by measuring the time it takes for the radio waves to bounce off the ground and return to the aircraft. | They provide accurate altitude measurements above the ground so pilots can make informed decisions during landing and take off during foggy weather. |
Laser Altimeters | They employ lasers to measure the distance between the aircraft and the ground below. | By calculating the time it takes for the laser beam to reflect back, laser altimeters can determine the aircraft's precise altitude. |
Incorrect readings
Altitude deviations
or malfunctioning displays.
These issues can often be attributed to factors such as instrument calibration, mechanical wear and tear, or electrical faults. If you encounter any of these issues, you will either need to do some maintenance or replace the altimeter.
Let’s look at some great maintenance practices you can apply to your altimeters to prevent having to replace them and some troubleshooting tips you can regularly do to keep your parts in top quality shape.
The 5 Best Tips to Maintain and Troubleshoot Your Altimeter
Regular maintenance practices and troubleshooting is essential for the correct functioning of aircraft altimeters. Here are some great tips to keep your parts in top-quality shape:
Perform regular calibration checks
Clean your altimeter after each flight
Perform regular visual inspections.
Follow the manufacturer's recommendations
Consult qualified professionals for any maintenance procedures.
With a comprehensive understanding of aircraft altimeters, their components, types, and maintenance, pilots can confidently rely on these instruments for accurate altitude readings and safe navigation during flight.
