A Summary of Unmanned Aircraft Accident/Incident Data: Human Factors Implications

A review and analysis of unmanned aircraft (UA) accident data was conducted to identify important human factors issues related to their use. UA accident data were collected from the U.S. Army, Navy, and Air Force. Classification of the accident data was a two-step process. In the first step, accidents were classified into the categories of human factors, maintenance, aircraft, and unknown. Acci...

Unmanned aircraft systems as wingmen

This paper introduces a method to integrate Unmanned Aircraft Systems (UASs) into a highly functional manned/ unmanned team through the design and implementation of 3D distributed formation/flight control algorithms with the goal to act as wingmen for a manned aircraft. The proposed algorithms are designed to increase UAS autonomy, dynamically modify formations, utilize standard operating forma...

A Mobile Aircraft Tracking System That Supports Unmanned Aircraft Operations

The integration of unmanned aircraft into the national airspace system requires new methods of ensuring collision avoidance. For unmanned aircraft a capability to ‘detect-and-avoid’ is required to replace the traditional ‘see-andavoid’ performed by pilots. The initial results from testing a Mobile Aircraft Tracking System (MATS) show that this ground-based radar system can track a ScanEagle unm...

Reconnaissance and Surveillance in Urban Terrain with Unmanned Aerial Vehicles

Unmanned vehicles endowed with attributes of intelligence are finding applications in reconnaissance, surveillance, and rescue operations in both military and civilian domains. We are introducing a methodology to locate a number of such Unmanned Aerial Vehicles (UAVs) optimally over an urban environment and identify and track potential ground targets using a particle filtering framework. The pa...
