The thesis is an investigation on current regulations of commercial aircraft landing and take-off procedures and an analysis of potential weaknesses within the regulatory system for commercial aerospace. To determine such flaws, an area of worse-case scenarios with regard to the aforementioned flight operations was researched. The events selected to best-depict these scenarios where incidents of aircraft overrunning the runway, referred to as runway excursions. A case-study conducted of 44 federal investigations of runway excursions produced data indicating four influential factors within these incidents: weather, pilot error, instrument malfunction, and runway condition. Upon examination, all but pilot error appeared to have federal enforcement to diminish the occurrence of future incidents. This is a direct result of the broad possibilities that make up this factor. The study then searched for a consistent fault within the incidents with the results indicating an indirect relationship of thrust reversers, a technique utilized by pilots to provide additional braking, to these excursions. In cases of thrust reverser failure, pilots' over-reliance on the system lead to time being lost from the confusion produced by the malfunction, ultimately resulting in several different runway excursions. The legal implication with the situation is that current regulations are ambiguous on the subject of thrust reversers and thus do not properly model the usage of the technique. Thus, to observe the scope of danger this ambiguity presents to the industry, the relationship of the technique to commercial aerospace needed to be determined. Interviews were set-up with former commercial pilots to gather data related to the flight crew perspective. This data indicated that thrust reversers were actively utilized by pilots within the industry for landing operations. The problem with the current regulations was revealed that the lack of details on thrust reverser reflected a failure of regulations to model current industry flight operations. To improve safety within the industry, new data related to thrust reverser deployment must be developed and enforced to determine appropriate windows to utilize the technique, thus decreasing time lost in confusion that results from thrust reversers malfunction. Future work would be based on producing simulations to determine said data as well as proposing the policy suggestions produced by this thesis.
