What is Failsafe, the Key to Security?

Hello dear readers! Today, we will discuss the topic of "Failsafe", one of the most critical safety features of drone technology, in detail. We will examine what failsafe is in general terms and how this feature works in popular flight control software ArduPilot and PX4.

What is Failsafe?

Firstly, let's consider the term "Failsafe" in its general meaning. Failsafe is a feature that enables systems to switch to a safe state as a result of errors or unexpected situations that may occur in a system. In other words, thanks to the failsafe feature, the system intervenes with minimal or no damage in the event of an error.

Failsafe is particularly important in drone technology. Because in the event of loss of control of a drone or a technical malfunction, serious risks may occur both for the drone and its surroundings. At this point, failsafe comes into play and allows the drone to land safely or return to a designated point.

Now, let's see how the failsafe feature works in ArduPilot and PX4 flight control software.

ArduPilot Failsafe Features

ArduPilot offers a wide range of failsafe options. These options include situations such as loss of radio signal, battery low voltage and GPS loss. Different failsafe actions can be specified for each situation. For example, in case of loss of radio signal, the drone can return to a specified point at a specified height or make an automatic landing. In case of battery low voltage, the drone can be automatically directed to the nearest landing point.

PX4 Failsafe Features

Similarly, the PX4 flight control software provides solutions for various failsafe situations. Different failsafe actions can be specified for situations such as loss of radio signal, battery low voltage, engine failure and GPS loss. PX4 also offers the possibility to pre-test and set the specified failsafe actions.

As a result, a failsafe is one of the most important safety features of drone technology. Both ArduPilot and PX4 increase the safety of drone operations by using this feature effectively. If you are a drone user, be sure to set the failsafe options in your flight control software correctly.

Remember, safety always comes first!

Until next time, we wish you safe flights!
