Being an embedded developer at **_Luxoft India_**, I got to know about the applications of Embedded Systems in Automotive domain. So out of curiosity I extended my researches to other areas which have similar applications. Here I would like to share a brief knowledge of one such applications of Embedded systems in Avionics.

**Abstract**

The aviation sector significantly relies on embedded systems to carry out crucial tasks that guarantee flight efficiency and safety. Computer systems with specialized functionality known as embedded systems are created to carry out certain tasks inside bigger systems. In this paper, we describe the numerous avionics embedded system applications and how they improve flight efficiency and safety.

**Introduction** 

One of the most heavily regulated sectors of the global economy is aviation. The effectiveness and safety of flight are of the utmost significance. The electronic systems used aboard airplanes, or avionics, are essential to the effectiveness and safety of flight. Avionics primarily relies on embedded systems, which are specialized computers made to carry out particular tasks inside bigger systems.

**Application** **of** **Embedded** **System** **in** **Avionics**
 
1. Flight control system-
Flight control systems, which are in charge of regulating the movement of the aircraft, utilize embedded systems. The control surfaces are adjusted by these systems in response to changes in the position and orientation of the aircraft, which are detected by sensors. The tracking of the aircraft's speed, altitude, and direction is done by embedded systems.


2. Communication system-
Communication systems, which are in charge of sending and receiving data between the aircraft and ground stations, utilize embedded systems. These systems employ a range of communication protocols, such as satellite, VHF, and HF.

3. Navigation system-
The navigation systems, which are in charge of figuring out the position and orientation of the aircraft, utilize embedded systems. These systems use a range of sensors, such as inertial and GPS sensors, to deliver precise positional data.

4. Flight management system-
Flight management systems, which are in charge of overseeing the flight plan for the aircraft, employ embedded technology. These technologies optimize the flight plan and make sure the aircraft reaches its destination quickly and safely using a range of inputs, including meteorological data and air traffic control data.

5. Engine management system-
Engine management systems, which are in charge of observing and managing the aircraft's engines, employ embedded technologies. In order to optimize engine performance, these systems use sensors to monitor engine performance and modify engine settings including fuel flow and ignition timing.

**Benefits** **of** **Embedded** **System** **in** **Avionics**

1. Increased safety-
By giving pilots and ground controllers precise and trustworthy information, embedded technologies in avionics contribute to improving flight safety. The redundant sensors and communication protocols used by these systems guarantee that vital information is constantly accessible.

2. Improved efficiency-
Avionics embedded systems optimize engine performance and flight planning to increase flying efficiency. As a result, there is a decrease in fuel use, a shorter flying time, and lower expenses.

3. Enhanced pilot system-
By providing real-time information and easing the pilot's workload, embedded technologies in avionics improve the pilot experience. This enables pilots to concentrate on other important duties including keeping an eye on the aircraft's systems and handling emergencies.

**Disadvantages** 

1. Complexity-
Avionics embedded systems can be extremely complex and sophisticated, necessitating substantial development and testing to guarantee their functionality. Longer development periods and higher development expenses may follow from this.

2. Reliability-
In avionics, the dependability of embedded systems is crucial, and any malfunction or failure can have serious repercussions. Although thorough testing and redundancy might lessen this risk, it is still something to be concerned about.

3. Security-
Using embedded systems in avionics also poses security issues. These systems can be subject to hacking or cyberattacks since they are frequently interconnected with other systems and networks, which could jeopardize the aircraft's safety and security.

4. Maintenance-
It can be difficult to maintain embedded equipment, particularly in older airplanes. Finding trained individuals to carry out maintenance and repairs might be challenging as these systems get more sophisticated and complicated.

5. Cost-
The price of air travel may be impacted by the high cost of developing and implementing embedded technologies in avionics. Additionally, it might be expensive to maintain and upgrade these systems over time.

**Upcoming** **applications** **of** **Embedded** **Systems** 

1. Health monitoring-
Real-time monitoring of the health of aircraft parts using embedded technologies can give maintenance staff the most recent information on the state of vital parts. This can assist in spotting possible issues before they become serious, lowering maintenance costs and enhancing safety.

2. Augmented reality (AR)-
Embedded systems can be used to integrate Augmented Reality (AR) technologies with avionics systems, giving pilots access to real-time data on weather, flight conditions, and other important variables. As a result, situational awareness and decision-making may be improved, increasing security and effectiveness.

3. Advanced communication-
Faster and more dependable connectivity for airplanes can be provided by modern communication systems, such as 5G networks. These cutting-edge communication technologies can be incorporated into aviation systems using embedded systems, opening up new possibilities including real-time data transfer and remote monitoring.

**Conclusion** 

Avionics embedded systems play a crucial role in ensuring flight efficiency and safety. The aviation sector continues to rely significantly on embedded systems, and technological advancements will only serve to improve their capabilities. Embedded systems will remain essential to the safe and effective operation of aircraft as the aviation sector develops.
