Systems and methods provide dynamically modifiable parameters in required time of arrival (RTA) speed regions of an assigned flight path of an aircraft. The system includes a vertical situation display (VSD) rendering thereon a vertical flight profile of the assigned flight path. A control module is coupled to the display system and configured to: demark the vertical flight profile with a plurality of RTA speed regions related to an initial speed profile; render an RTA speed band graphic having demarked sections vertically representing a speed minimum and speed maximum for an respective RTA speed region, the RTA speed band graphic representing a normalized speed range between zero and a maximum value for each respective RTA speed region. The control module accepts user modifications and updates the RTA speed band graphic and the current speed profile to reflect user input.

Dynamically modifiable parameters in required time of arrival (RTA) regions of an assigned flight path

A method is provided for controlling speed of a vehicle. The method includes determining an arrival time error (ATE) for a required time of arrival (RTA) and a projected trajectory according to a travel plan with a current speed profile having a plurality of regions, each with a respective speed adjustment parameter (SAP) and a respective SAP value relative to a nominal speed profile. The method further includes selecting, when the ATE is greater than a threshold, one of the regions as a selected region for modification based on a priority order of the regions. The method further includes modifying the current speed profile by adjusting the respective SAP value for the selected region according to the respective SAP in order to decrease the ATE; and implementing the modified speed profile.
