Description
The objective of this study was to investigate if 911 operators experience similar stressors and amounts of stress as law enforcement, fire, and EMS personnel. To accomplish this, I conducted a focus group to obtain information about similar stressors experienced by all three areas of emergency services. Then I utilized this information to form a survey to quantify the amounts of stress experienced by emergency service personnel. My findings indicate that the stress experience is similar.

Description
The primary objective of this research paper is to gather information on how individuals engaged in flight operations and maintenance activities perceive the expanding role of automation as it relates to the integration of Uncrewed Aerial Systems Traffic Management (UTM) into the National Airspace System (NAS). Rulemaking efforts to address operations beyond visual line of sight (BVLOS), including operations over people, performance requirements for aircraft, and operator qualifications, among others, have been ongoing. Decisions regarding a system architecture that reflects requirements of a fully automated service model that interfaces with current Air Traffic Services systems are yet to be finalized. Gaining the perspective of individuals currently working in the field of aviation is an important step in gauging any resistance to change and support for the rapid evolution occurring in the global Air Traffic Management (ATM) system.

Description
This thesis explores the human factors effects pilots have when controlling the aircraft during the takeoff phase of flight. These variables come into play in the transitory phase from ground roll to flight, and in the initiation of procedures to abort a takeoff during the ground run. The FAA provides regulations for manufacturers and operators to follow, ensuring safe manufacture of aircraft and pilots that fly without endangering the passengers; however, details regarding accounting of piloting variability are lacking. Creation of a numerical simulation allowed for the controlled variation of isolated piloting procedures in order to evaluate effects on field performance. Reduced rotation rates and delayed reaction times were found to cause significant increases in field length requirements over values published in the AFM. A pilot survey was conducted to evaluate common practices for line pilots in the field, which revealed minimum regulatory compliance is exercised with little to no feedback on runway length requirements. Finally, observation of pilots training in a CRJ-200 FTD gathered extensive information on typical piloting timings in the cockpit. AEO and OEI takeoffs were observed, as well as RTOs. Pilots showed large variability in procedures and timings resulting in significant inconsistency in runway distances used as well as V-speed compliance. The observed effects from pilot timing latency correlated with the numerical simulation increased field length outputs. Variability in piloting procedures results in erratic field performance that deviates from AFM published values that invite disaster in an aircraft operating near its field performance limitations.
