1. A system comprising:
a processor; and
a memory coupled to the processor, the memory including a set of instructions, which when executed by the processor, causes the system to:
identify a flight path, wherein the flight path includes a plurality of segments that each include a waypoint;
identify a flight profile that includes one or more of desired velocities or desired altitudes;
calculate a first horizontal distance from a beginning of the flight path to reach the one or more of the desired velocities or the desired altitudes to comply with a constraint associated with an aircraft;
identify a first waypoint from the plurality of segments based on the first horizontal distance; and
adjust the first waypoint to reach the one or more of the desired velocities or the desired altitudes.
