Satellite-Based Real-Time Thunderstorm Nowcasting for Strategic Flight Planning En Route

Abstract

The added value of a satellite-based thunderstorm detection and nowcasting system with respect to flight safety and efficiency is shown by comparing onboard observations carried out by Deutsche Lufthansa AG and Deutsches Zentrum für Luft- und Raumfahrt pilots to the detection and nowcasting information in both postflight analyses and in real time. For the first time, detection and nowcasting data could be successfully uplinked into the cockpit of aircraft during flight in real time, thereby demonstrating that these data are in good agreement with the returns of the onboard radar, and furthermore provide an overview of the thunderstorm situation around the aircraft and along the aircraft’s flight track. Pilots can use the detection and nowcasting information to strategically plan their route up to 1 h ahead in time. The result is safer flight routes that avoid inadvertent flights through areas where thunderstormrelated hazards like turbulence, icing, and hail occur. In addition, the improved strategic planning enables smarter flight routes, resulting in fuel savings, reduced delays, and less deviations to alternates.
