Indicators and sensors provide real-time data on everything from altitude and airspeed to engine performance and overall system health. That's why we're proud to offer a comprehensive collection of aircraft indicators and sensors for sale on our category page.

Understanding Aircraft Indicators and Sensors

Why Indicators and Sensors are Important

Given the high stakes nature of aviation, it's no exaggeration to say that reliable indicators and sensors are the backbone of the industry. They help in a plethora of ways when on flight, here are a few:

  • They are needed to make split-second decisions while flying

  • They help ensure that the aircraft is safe to fly before each flight. 

  • They assess the aircraft's speed, altitude, and other critical factors.

  • They are needed to troubleshoot issues and diagnose problems.


Simply put, without good indicators and sensors, a safe flight just isn’t possible. So when it comes to choosing the correct gear for you, don’t make the decision lightly.

How Indicators and Sensors Work in Aircraft

Essentially, sensors throughout the aircraft gather data on various systems and feed that information back to the cockpit, where indicator systems present it in an easily digestible format. Meanwhile, diagnostic sensors feed data directly to maintenance systems on board, providing insight on engine health, fuel consumption, and more.

The 5 Types of Aircraft Indicators and Sensors for Sale

Now that we've explored what indicators and sensors are, their importance, and some considerations, let's take a closer look at some of the most essential indicators and sensors that we offer for sale:

Attitude indicators, also known as artificial horizons, give pilots a clear understanding of their aircraft's orientation relative to the horizon. Our selection includes a range of analog and digital models to meet your needs.

But first, let’s get into what indicators and sensors are, why they are crucial for your aircraft, and what types and brands are available on our website. That way when it comes time to make a decision, you will be very well-versed on the topic.

Essentially, an indicator is a device that presents information about a system or condition in an easily digestible format. A sensor is the mechanism that gathers data on the system to provide that information to the indicator. Together, indicators and sensors work hand in hand to give pilots and maintenance personnel the details they need on aircraft performance.

Can Aircraft Indicators and Sensors Fail? 

It's important to note that indicators and sensors are not infallible; they can be affected by factors such as:

  • Weather conditions

  • Electromagnetic interference

  • And mechanical failures.

That's why it's crucial for pilots and maintenance personnel to have a thorough understanding of how these devices work, as well as backup systems and procedures in place in case of failure.

Though, as technology continues to advance, we can expect to see even more sophisticated sensors and indicators that further improve aviation safety and performance.

1. Airspeed Indicators

Airspeed indicators are a critical component of aircraft safety, providing pilots with real-time feedback on their speed relative to the surrounding air. Our selection includes a range of different models, so you're sure to find the one that's right for your aircraft.

2. Altimeters

Without reliable altimeters, pilots wouldn't be able to get a clear picture of how high they are flying, which is a critical component of safe flying. Our selection includes both digital and analog models.

3. Vertical Speed Indicators

Vertical speed indicators give pilots real-time feedback on how quickly they are ascending or descending. This data is essential for maintaining a stable altitude and avoiding issues like stall conditions. Our selection of vertical speed indicators includes a range of different models for different aircraft types.

4. Attitude Indicators

5. Engine Sensors

Finally, we have a range of engine sensors for sale to help you monitor the health of your aircraft's engine. From oil pressure to exhaust temperature, these sensors provide real-time feedback to help you avoid issues like engine failure. Our selection includes many top brands, so you can trust that your aircraft is in good hands.
