AI in aviation: A runway to smarter airports

The aviation industry keeps the world connected by transporting people and goods. As technology advances, an increasing number of people are traveling. This year, global passenger traffic is expected to reach 9.4 billion. Monitoring airport operations is more important than ever to avoid expensive delays and keep passengers from having a bad travel experience.

Artificial intelligence (AI) in airports can help streamline operations, boost efficiency, and improve the overall travel experience. In this article, we’ll explore various applications of AI in the airline industry. We’ll also take a look at the advantages of AI in aviation and the challenges that come with it.

How is AI used in aviation?#

Different AI technologies like machine learning, natural language processing (NLP), and computer vision are transforming the aviation industry. Machine learning uses algorithms to identify patterns and make predictions. It can help optimize flight schedules, improve aircraft turnaround times, and predict equipment failures before they happen.

NLP, which allows computers to understand and generate human language, can be used for applications like sentiment analysis. By analyzing passenger feedback from surveys, social media, and customer reviews, NLP can help airlines and airports gauge customer satisfaction and identify areas for improvement.

Computer vision makes it possible for computers to interpret and make decisions based on visual data. It can be used in advanced surveillance systems to strengthen security through applications like facial recognition, behavior analysis, and detection of suspicious activity. These are merely a few uses of AI within the aviation field. Let's look at how these technologies are impacting the field in more detail.

Applications of AI in aviation#

To get a clearer picture of how these AI applications are reshaping aviation, let's look at a few detailed examples. We'll understand the need for the application, the solution we can create using AI, and how it works.

Using computer vision to calculate airplane landing distances#

An interesting application of computer vision in aviation is calculating airplane landing distances. Although it’s not commonly used yet, computer vision can serve as a backup if instruments fail and help with landing in low-visibility situations. It can make landing procedures safer and more reliable. Unlike the traditionally used Instrument Landing System (ILS), which provides guidance to aircraft during landing using radio signals, computer vision offers support from the ground.

Object detection is a computer vision task in which AI models identify and locate objects within an image or video. It is essential for various applications, from autonomous vehicles to security systems. In this particular application, object detection can be used to accurately identify the airplane and its landing spot.

Ultralytics YOLOv8, for instance, is an advanced computer vision model that supports object detection, which can be used for this. The airplane and where it should land can be detected, and bounding boxes can be drawn around the objects. Then, you can measure the gap between the two objects by using the center of the bounding boxes.

To integrate this into existing airport infrastructure, cameras positioned along the runway could feed video data to the YOLOv8 model in real time. The system would continuously monitor the landing approach, providing instant feedback to air traffic controllers and pilots about the exact landing distances. The system would make it easier to calculate airplane landing distances in challenging conditions.

AI chatbots make airport customer service smarter#

One major issue in airports is the constant need for customer support. Passengers often require assistance with flight information, check-in processes, and navigating the airport. This can end up overwhelming the staff and creating longer wait times. AI chatbots built using NLP and Large Language Models (LLMs) like GPT-4o can help.

NLP and LLMs let chatbots understand and generate human language. They can interact with passengers in a natural, conversational way. In airports, these chatbots can efficiently manage various tasks because they draw on extensive knowledge from their training data. Passengers can use chatbots to get real-time flight information, answer questions about airport facilities, assist with booking and check-in processes, and even offer recommendations for dining and shopping.

AI-enabled baggage handling systems#

AI in airports can make the process of transporting and collecting check-in baggage more efficient and reduce the likelihood of lost luggage. Airports can streamline baggage sorting, tracking, and management using technologies like computer vision and machine learning.

Ultralytics YOLOv8 supports object tracking and instance segmentation, making it a good option for this application. Object tracking lets us follow the movement of each piece of luggage from the moment it is checked in until it is loaded onto the aircraft. Continuous monitoring helps prevent mistakes and ensures that every bag reaches its destination.

Instance segmentation helps identify and distinguish each piece of luggage individually. It is useful for tasks like counting luggage on the collection carousel. The AI-enabled baggage handling systems can keep track of the number of bags as they are placed on the carousel and as passengers collect them. With this type of monitoring, airlines can help ensure that no bags are left unclaimed and that all passengers receive their luggage.

Integrating computer vision models like YOLOv8 into baggage handling can make these processes much more efficient and accurate. Real-time monitoring and data collection help reduce mistakes, minimize lost luggage, and improve passenger satisfaction. By automating these tasks, airport staff can focus on more important tasks to improve the airport's overall efficiency.

Keeping an eye on airport ground operations#

We explored monitoring baggage handling using computer vision, but that is just one aspect of ground operations. Many other aspects of ground operations can be monitored and tracked to identify where delays are occurring. Identifying and eliminating delays can reduce losses and improve overall efficiency.

From refueling and maintenance to catering services and ramp safety, computer vision systems can use cameras and sensors to watch over ground operations. These systems analyze the visual data to spot any issues, streamline workflows, and make sure safety rules are followed. Over time, these insights can help airports continuously improve their operations, leading to smoother, safer, and more efficient ground handling processes.

Challenges of implementing AI in airports#

Various roadblocks may occur while implementing AI applications in airports. Some of the more commonly known challenges are related to high infrastructure costs, data privacy, ethical implications, and integration with legacy systems. However, these challenges also arise in other industries. In aviation, there are specific challenges unique to the sector.

Making sure AI systems are reliable and safe is key in aviation. AI has to meet strict standards and go through a lot of testing because any glitch could result in serious consequences. Another challenge is that adapting to different airport environments can be difficult. Airports work in all kinds of climates, with different levels of passenger traffic and types of aircraft. AI systems need to handle these diverse conditions. Also, getting approval from regulatory bodies and industry stakeholders can be tough. AI systems must follow strict safety regulations, and this can slow down the process of developing and deploying AI solutions. Convincing airlines, airport operators, and passengers that AI is reliable and beneficial takes a lot of effort and proof that it really works to improve safety and efficiency.

The future of AI in aviation#

As AI technologies keep improving, we can expect even better efficiency, safety, and passenger experiences. For instance, Singapore's Changi Airport uses AI-powered immigration systems that let passengers clear immigration in less than a minute. There is also work being done on autonomous aircraft and AI plays a major part in navigation and decision-making. Integrating AI across various parts of aviation won't just improve current operations but will also lead to new and innovative solutions we haven't even thought of yet.
