Addressing Missing Data in NOTAM and METAR Systems

Introduction

This case study examines the strategies employed to handle missing data in Notice to Airmen (NOTAM) and Meteorological Aerodrome Reports (METAR) systems. Focusing on the development of data analysis techniques, the study highlights the implementation of auto-fill or rejection policies for abnormal NOTAMs and the generation of synthetic missing METAR information. Additionally, it emphasizes the importance of ML Ops practices for maintaining the efficiency and reliability of NOTAM and METAR AI systems.

Challenges
