Task Introduction:

We invite you to participate in our user study to evaluate the utility of recommended missing requirement concepts in the UAV (Unmanned Aerial Vehicle) domain.

Task Steps:

1. You will receive a complete document containing a set of UAV requirements, including 70% of the requirements.
2. We have already removed 30% of the requirements, which are considered as missing requirements for a system.
3. Your task is to:
   • First, reading the 70% of the requirements to understand the context and background of the UAV domain.
   • For each recommended missing requirement concept, rate it to indicate whether the concept would be helpful in writing the missing 30% of the requirements. You can use a predefined rating system, such as 1 to 5, where 1 indicates "Not Helpful" and 5 indicates "Very Helpful."

Time Estimate:

Completing the entire task may take 3-5 minutes, depending on your familiarity with the domain and your rating speed. The task includes some domain-specific knowledge in the UAV field, so it may take some additional time to understand the requirements.

Requirements:

You should have a certain level of familiarity with the UAV domain to effectively evaluate the practicality of the missing requirement concepts.

Important Note:

Your feedback is crucial for our research and will help improve the recommendation methods for missing requirements concepts, enhancing the quality and reliability of UAV systems. Thank you for participating in this study!

Here is the 70% UAV requirements description:

17 . When requested the Coordinate System shall transform coordinates to alternate formats.

18 . When given two coordinates the Coordinate System shall compute the direction from the first coordinate to the second coordinate.

19 . When the hover in place command is issued the Flight Manager shall halt the UAV in place and maintain its current position.

21 . The Mission Planner shall manage predefined Flight Patterns

22 . When requested if a mission is currently active the Mission Planner shall cancel the active mission.

23 . When requested the Single UAV Flight Plan Scheduler shall schedule a route for execution.

24 . If a route contains a specific UAV ID the Single UAV Flight Plan Scheduler shall assign the route to the given UAV.

25 . If a scheduled flight is not manually assigned to a UAV the Single UAV Flight Plan Scheduler shall assign the route automatically to an UAV

33 . When given a goto command the Internal Simulator shall update the location of the UAV at increments of SIMULATION STEP SIZE meters moving it towards the target destination until the destination is reached.

34 . The Internal Simulator shall approximate the state of the battery

35 . The Activity Logger shall log all flight plan related events.

36 . The Activity Logger shall log all commands sent to and messages received from a GCS.

41 . When the Vaadin UI is activated the Vaadin UI shall be configured according to stored configuration parameters.

42 . When loading the map view it shall be positioned at the pre-defined location

43 . When a route is assigned or removed from a UAV the Route Assignment UI shall notify Dronology.

44 . When a UAV is selected the Route Assignment UI shall display its active flight plans.

45 . A user may reorder routes or remove flight plans assigned to a UAV as long as the flight has not started execution.
