Low-Cost Wearable Head-Up Display For Flight General Aviation, Pavan K. Chinta

Doctoral Dissertations and Master's Theses

A low-cost wearable Commercial-off-The-Shelf (COTS) Augmented Reality (AR) Head-Up Display (HUD) system is designed, successfully reduced to practice, and flight tested. The system is developed based on the need for a technology that improves loss-of-control (LOC) safety in the General Aviation (GA) sector. The accuracy of the flight-path based system is determined to be within a degree of the truth source. The repeatability of the data from the COTS system is excellent. A complementary filter is proposed for air data flow angles and successfully flight tested for straight and level flight, dynamic maneuvering, and atmospheric turbulence, provided that a reasonably …

Applications Of The Technology Acceptance Model To Integration Of The Automatic Ground Collision Avoidance System In Fighter Aircraft Operations, Casey Richardson

Doctoral Dissertations and Master's Theses

The leading cause of F-16 fighter aircraft and fighter pilot losses is ground collisions. In an effort to curb this hazard, an automatic ground collision avoidance system (AGCAS) was formally fielded for use in routine U.S. Air Force active-duty F-16 operations in 2014. AGCAS uses a high-level automation design capable of altering the aircraft’s flight control system independent of pilot action.

This study explored an application of the Technology Acceptance Model (TAM) to integration of the AGCAS in fighter aircraft operations. Using data from a survey of active-duty U.S. Air Force F-16 operational fighter pilots (n=142), collected shortly after initial …

The Extent Of Distraction Of Cell Phone Conversations For Passengers In Simulated Flight, Tianhua Li

Doctoral Dissertations and Master's Theses

Currently, passengers are forbidden from making cell phone calls during flights in the United States due to cellular electronic interference. However, some related research has demonstrated that the use of cell phones has little interference with avionics. Furthermore, any potential electronic interference can be eliminated by using new technology. Although talking on the cell phone does not cause electronic interference, the distraction of a passenger caused by a cell phone may negatively impact safety. The cell phone calls have been found to affect people’s attention and performance. In-flight announcements are popular methods to inform commercial airliner passengers of their situation …

An Archival Analysis Of Stall Warning System Effectiveness During Airborne Icing Encounters, John Michael Maris

Doctoral Dissertations and Master's Theses

An archival study was conducted to determine the influence of stall warning system performance on aircrew decision-making outcomes during airborne icing encounters. A Conservative Icing Response Bias (CIRB) model was developed to explain the historical variability in aircrew performance in the face of airframe icing. The model combined Bayes’ Theorem with Signal Detection Theory (SDT) concepts to yield testable predictions that were evaluated using a Binary Logistic Regression (BLR) multivariate technique applied to two archives: the NASA Aviation Safety Reporting System (ASRS) incident database, and the National Transportation Safety Board (NTSB) accident databases, both covering the period January 1, 1988 …
