This white paper proposes a global, AI-powered aviation architecture where a centralized Large Language Model (LLM) system replaces legacy flight planning constructs such as SIDs, STARs, airways, and ground-based navaids. It introduces a paradigm shift in trajectory planning, regulatory integration, airspace management, and aircraft communication using real-time digital technologies including ADS-B, CPDLC, space-based internet, and mesh networking. This version expands on the challenges and opportunities of this approach, including scalability, security, regulatory considerations, and the role of human-machine interfaces.

1. Introduction

The current aviation ecosystem relies on static, pre-published routes and manual decision-making, leading to inefficiencies, delays, and conflicts. The proposed system leverages a globally accessible LLM that dynamically generates optimal 4D flight trajectories for every aircraft, in real-time, while adhering to geopolitical, regulatory, environmental, and operational constraints.
