Patent attributes
An interactive speed profile bar that enables crew awareness of the overall planned flight trajectory speed profile. The speed profile bar will have a graphical depiction (e.g., virtual buttons having alphanumeric symbology) of some or all of the speed segments of the speed profile. Each graphical element (e.g., virtual button) includes symbology identifying the applicable speed mode and corresponding target speed change. Each speed segment will start at the inflection point where the speed change will occur in the flight plan, and will continue until the next trajectory speed change. The speed profile bar will be interactive, allowing the flight crew to select the speed segment to change, in response to which selection the system displays graphical user interface elements showing a menu of the available speed segment options. Each individual speed segment is represented by an individual virtual button that can be selected by touching the screen or other input device.
