A majority of instruments relied on survey data (88%) (Table 3), either alone (n = 76), or in combination with data collected from chart reviews (n = 4), administrative claims (n = 1), or all three data types (n = 3).
Both pilots apparently were flying without the help of instruments, relying on their vision to navigate.
In addition, most self-report instruments rely on a numerical Likert scale or a system of "emoticons" in which students identify their agreement based on a scale (e.g., 1 5 with 1 representing a low level of agreement and 5 representing the highest level of agreement with a given statement).
