G-NAV: Soaring the Clouds with AdaWebPack

by Fernando Oleo Blanco at Ada Developers Workshop 2024.
Electronic Flight Instrument Systems (EFIS) can effectively increase situational awareness of glider pilots by combining geographic data, aeronautical data, aircraft performance models, geolocation systems and air traffic surveillance systems. While Progressive Web Applications (PWA) are consolidating in the world of mobile technology, G-NAV explores these new possibilities to provide an alternative EFIS solution, carrying Ada along as the main programming language through the AdaWebPack toolchain. With a single code base, the solution can be integrated to different systems in different ways, as it can be provided through the internet or through an onboard data acquisition system. From a developer's perspective, G-NAV implements several particular features, like using its own vector graphics library on top of WebGL to draw shapes, lines and even text on a single canvas. This results in a vivid minimalistic interface that prioritizes awareness and robustness. Finally, the project seeks to promote open access to a tool that can have a positive impact on safety.
