The Department of Aerospace Engineering seeks to instruct the design, analysis, testing, and operation of vehicles which operate in air, water, or space, including studies of aerodynamics, structure mechanics, propulsion, and the like.

The Department of Aerospace Engineering was organized as the Department of Aeronautical Engineering in 1942. Its name was changed to the Department of Aerospace Engineering in 1961. In 1990, the department absorbed the Department of Engineering Science and Mechanics and became the Department of Aerospace Engineering and Engineering Mechanics. In 2003 the name was changed back to the Department of Aerospace Engineering.

Computer Science—the theory, representation, processing, communication and use of information—is fundamentally transforming every aspect of human endeavor. The Department of Computer Science at Iowa State University advances computational and information sciences through; 1. educational and research programs within and beyond the university; 2. active engagement to help define national and international research, and 3. educational agendas, and sustained commitment to graduating leaders for academia, industry and government.

The Computer Science Department was officially established in 1969, with Robert Stewart serving as the founding Department Chair. Faculty were composed of joint appointments with Mathematics, Statistics, and Electrical Engineering. In 1969, the building which now houses the Computer Science department, then simply called the Computer Science building, was completed. Later it was named Atanasoff Hall. Throughout the 1980s to present, the department expanded and developed its teaching and research agendas to cover many areas of computing.

Electrical and Computer Engineering

The Department of Electrical and Computer Engineering (ECpE) contains two focuses. The focus on Electrical Engineering teaches students in the fields of control systems, electromagnetics and non-destructive evaluation, microelectronics, electric power & energy systems, and the like. The Computer Engineering focus teaches in the fields of software systems, embedded systems, networking, information security, computer architecture, etc.

The Department of Electrical Engineering was formed in 1909 from the division of the Department of Physics and Electrical Engineering. In 1985 its name changed to Department of Electrical Engineering and Computer Engineering. In 1995 it became the Department of Electrical and Computer Engineering.

Unmanned Aerial Systems (UAS) are quickly integrating into the National Air Space (NAS). With the number of registered small (under 55 pounds) UAS in the USA alone at over 1.5 million, and projected to expand rapidly, according to the Federal Aviation Administration (FAA), safety is a pressing consideration. Safe UAS integration into the NAS requires an intelligent, automated system for UAS Traffic Management (UTM). Even more than for manned aircraft, UTM must integrate runtime checks to ensure system safety, at the very least to make up for the lack of humans on board to employ the common-sense safety checks ingrained into the culture of human aviation.

We overview a candidate automated, intelligent UTM system and propose multiple integration points for runtime verification (RV) to ensure that each part of the UTM adheres to safety requirements during operation. We write, validate, and present patterns for formal requirements across multiple subsystems of this UTM framework. After encoding our requirements as flight-certifiable runtime observers in the R2U2 RV engine, we execute them in simulation across multiple real-life test flights supplemented with simulated data to cover additional cases that did not occur in flight. Lessons learned accompany an analysis of the efficacy and performance of RV integration into the UTM framework.
