Problem: The current method of turbulence detection using airborne radar is of limited use to flight crews. With the current method there is still a significant number of injuries due to turbulence.

Approach: As part of a NASA team, AeroTech developed improved turbulence detection techniques, taking advantage of current radar capabilities.

Enhanced Turbulence Radar Concept

  

Latest Developments (as of September 2005):   In August of 2004, AeroTech’s enhanced turbulence (E-Turb) algorithms were incorporated into a Rockwell Collins MultiScan® radar and installed in a Delta Air Lines B-737-800.   Since then the E-Turb radar system has been used and evaluated by Delta Air Lines pilots during commercial revenue flights throughout the United States and the Caribbean.   The evaluation program, being performed under the Turbulence Element (TPAWS) of NASA’s Aviation Safety and Security Program, is designed to evaluate the E-Turb radar system’s ability to increase the pilot’s situational awareness of turbulence, and assess the system’s ability to help reduce encounters with turbulence..   Recordings from the E-Turb radar have been downloaded on a routine basis, providing researchers ar Rockwell Collins and ATR the chance to evaluate the radar's performance.   The results of the analysis of the collected E-Turb radar data and the feedback from the Delta pilots have been extremely positive.   The evaluation will conclude in September of this year.
