Abstract: A user of a mobile device receives, through the mobile device, a request to dispatch a transport vehicle to a destination. In response to the request, the mobile device provides the user with a graphical user interface, which may be used to review information regarding the request and, if required, modify the information based on the fulfillment of the request. If the graphical user interface detects that the request has been fulfilled, the graphical user interface causes the mobile device to display a form specifying information associated with fulfillment of the request and modifiable by the user. Once the user has approved the provided information or has updated this information for accuracy, the graphical user interface causes the mobile device to transmit the completed forms to an aviation management service.
