Human Factors Affecting Safe Operation Data Analysis Chapter

From the descriptive in the Table 19, the respondents of the survey question 2 and 3 support the first null hypothesis and reject the alternative hypothesis. Based on the findings, the study supports the first null hypothesis that states:

H0: "Majority of UAV pilots do not agree that graduating from Undergraduate Pilot Training (UPT), to be under 40 years old and have a minimum of 100 flying hours are critical attributes that all safe UAV pilots should possess."

However, the study rejects the first research hypothesis that states:

H1: "Majority of UAV pilots will agree that graduating from Undergraduate Pilot Training (UPT), to be under 40 years old and have a minimum of 100 flying hours are critical attributes that all safe UAV pilots should possess."

Valenti et al. (2004) support the findings of the first hypothesis by pointing out that the major objective of the UAV is to execute mission without human interaction. UAV is remotely controlled aircraft where the pre-programmed flight plans are being controlled by complex dynamic automation systems. UAV is typically developed for number of mission including attack roles. UAV is also developed to eliminate the dangerous missions being carried out by the pilots of the manned aircrafts. In carrying out some of the missions, many pilots have lost their lives in the enemy combat, while some pilots have been killed during National Guard mission such as fires disaster, earthquake, and other natural disaster. Since the UAVs are remotely controlled by the automation systems, and not manned by the pilots "graduating from Undergraduate Pilot Training (UPT), to be under 40 years old and have a minimum of 100 flying hours" are not critical attributes that all safe UAV pilots should possess.

Testing the Second Hypothesis

The study proceeds to test the second null hypothesis that states:

Ho: "UAV pilots do not believe that lack of involvement in a "human related" aviation safety incident and possession of computer skills contributes to being a safe UAV operator in the USAF."

And the research hypothesis that states that:

H2: "UAV pilots believe that lack of involvement in a "human related" aviation safety incident and possession of computer skills contributes to being a safe UAV operator in the USAF."

To define the safety objectives of the UAV, it is essential to evaluate the current level of safety necessary for the human-piloted aircrafts. While manned pilot aircrafts consider the safety of the pilots and the people on board to be important, however, the safety of the UAV is considered relatively to the hazard that that it will cost to the community. Thus, the intervention of human related aviation safety

Human Factors in Aviation Brief Historical Background The Airline Industry has a history that dates back to 1903 when the Wright brothers made their first successful flight in Kitty Hawk, North Carolina. Initially the public did not take the idea of the airplane travel favorably. But this event marked the beginning of the Airline Industry as more and more inputs were given by people such as Charles Lindbergh who successfully completed a
