This report evaluates alternative methods for introducing enhanced bird threat information into the Air Traffic Control (ATC) environment. It is part of a larger multifaceted Federal Aviation Administration (FAA) effort to reduce significant bird strikes at civil airports nationwide. The FAA Airport Safety Research and Development Section sponsored...

... recent years, the Federal Aviation Administration (FAA) and industry researchers have noted a significant growth in wildlife strike reports [1]. Figure 1 shows the reported wildlife strikes between 1990 and 2013. The increasing trend in bird strike incidents is particularly alarming considering the losses caused by wildlife strikes. ...

... type and format of the bird threat information was identical to the WiSC text condition, with a few notable exceptions. First, the information was handwritten on a blank flight strip (see figure 10) as opposed to being presented on the radar display. Next, there was no color coding for threat level (i.e., only the plus (+) symbol was used to differentiate threat level). ...

... a rule, low-rating values were associated with low/less/disagree, whereas high-rating values were associated with high/more/agree. Figure 11 shows examples of rating scale anchors used in the questionnaires. All questionnaires can be found in the appendices. ...

... that the research team could not detect a statistical difference in self-reported subjective PSQ workload ratings across conditions. Figure 13 shows the mean and standard deviation for PSQ workload ratings. As stated above, the examination of potential workload differences across conditions is a key consideration in this simulation study. ...

... the rating of time spent looking at the radar between conditions. Figure 16 shows the mean and standard deviation across conditions. Time spent looking at the radar was an important consideration to measure because putting additional information on the radar display could theoretically lead to an increase in time spent looking at the radar display. ...

... were marginal differences between the perceived number of bird events by condition, χ 2 (3, N = 5) = 7.63, p =.053. Figure 17 shows the mean and standard deviation across conditions on perceived number of bird events. There was substantial variability in the ratings given in WiSC conditions, and particularly in the WiSC supervisor condition. ...

... research team was not able to detect a statistically significant difference between the WiSC target and WiSC text conditions. Figure 19 shows the mean and standard deviation across conditions. Participants rated the WiSC target condition as the most useful presentation method, followed by the WiSC text and WiSC supervisor conditions. ...

Although participants clearly rated the WiSC target condition most highly in terms of information quality, there was substantial variance in responses for the WiSC text and WiSC supervisor conditions. ...

In Europe, Medium Altitude Long Endurance (MALE) Remotely Piloted Aircraft Systems (RPAS) are only permitted to fly in segregated airspace. Because such restrictions limit civilian applications of MALE RPAS, several SESAR and EDA projects are currently working on the procedures needed to allow routine MALE RPAS flights in unsegregated European airs...
Air traffic management and specifically air-traffic control (ATC) rely mostly on voice communications between Air Traffic Controllers (ATCos) and pilots. In most cases, these voice communications follow a well-defined grammar that could be leveraged in Automatic Speech Recognition (ASR) technologies. The callsign used to address an airplane is an e...

The need to protect air traffic control against attacks and detect security incidents is widely accepted. Nevertheless, depending on the systems and procedures, it is sometimes difficult to distinguish whether "something is not as it should be". On the one hand, it could be due to a failure, on the other, it could be because of an intentional inter...
