this; green, amber and red. Where green represents that everything is fine in terms of alertness. Whilst amber and red are two warning limits that can be edited by the user. These indicate, depending on what the user’s own preferences are, limits that tell the user if a flight will be harder than normal flights (amber) or an extremely hard flight (red). If the the duty is another type of duty, for instance a Simulator Instruction session or a Ground Duty it is colored with a fix color for that duty type. These duties do not change color by alertness. Between duties there can in some cases be either a red or a green line, as in figure 2.4(b).

2.3. DESCRIPTION OF CREWALERT CHAPTER 2. BACKGROUND trip. Whilst red lines represent a mismatch in arrival and departure time zones. That is, the user is not departing from the time zone he or she last arrived at. Somewhere the user had to have relocated without marking it in the schedule in CrewAlert with, for instance, a dead-head flight. (a) (b) Figure 2.4: Duties without and with lines between them. Upon tapping a duty it expands down to the solid alertness curve giving a comparison on how the alertness will be during the flight, as seen in figure 2.5. To the left of the duty a tool tip box is displayed showing information about the duty. This includes departure and arrival airports and times, the time zone for these times, how many legs the duty consists of, the shift in time zones, the CAS score at top-of-decent and a comment on the flight, if the user enters one. Figure 2.5: An expanded duty, showing it’s tool-tip. The alertness goes beneath the amber limit, giving it a amber color. 8
2.3. DESCRIPTION OF CREWALERT CHAPTER 2. BACKGROUND Sleep/awake bar based on user data At the bottom of the schedule is another sleep/awake bar that shows user’s logged sleep and awake. These are logs with a start and end time, during this period the user is considered to be awake, if nothing else is entered. Inside of these logs the user can add a sleep period. Logs are colored white and sleeps are colored blue, as in figure 2.6. Upon tapping on a sleep period a tool tip box is displayed showing the start and end time of the sleep. Figure 2.6: The user based sleep/awake bar. Light bar In between the predicted and user’s sleep/awake bars there is a light bar, shown in figure 2.7. This bar shows the times the sun is up (white color) and down (black color) for the area the user is in at that time. Dusk and dawn are also shown (gray color) This is calculated with the help of the departure and arrival airports entered for the duties. Figure 2.7: The light bar. 2.3.2 Feature set Apart from the Graph view tab, CrewAlert also contains a number of prevalent features.
