Display systems and methods for providing displays indicating a required time of arrival

A method for providing a display to a flight crew of an aircraft includes receiving a required time of arrival (RTA) control instruction for arriving at a particular waypoint at a particular time, calculating an initial required aircraft speed at which the aircraft is required to fly in order to arrive at the particular waypoint at the particular time, and providing a flight display comprising a speed tape. The method further includes receiving an input accepting the RTA control instruction and calculating an updated required aircraft speed at which the aircraft is required to fly in order to arrive at the particular waypoint at the particular time. Still further, the method includes updating the flight display comprising displaying the updated RTA target speed on the speed tape using a second symbology that is different from the first symbology and discontinuing the display of the first symbology.
