1. A system for propulsor parking control for an electric vertical takeoff and landing (eVTOL) aircraft, the system comprising:
a plurality of lift propulsors mechanically coupled to the electric aircraft, the plurality of lift propulsors configured to:
generate lift when the eVTOL is hovering; and
park when the eVTOL is in wing-borne flight;
at least a first sensor configured to detect at least a first angular datum associated with a first lift propulsor of the plurality of lift propulsors;
at least a second sensor configured to detect at least a second angular datum associated with a second lift propulsor of the plurality of lift propulsors; and
a first controller communicatively connected to the first lift propulsor, the at least a first sensor, and the at least a second sensor, wherein the first controller is configured to:
generate a trajectory as a function of the atleast a first angular datum and the at least a second angular datum; and
adjust deceleration of the first lift propulsor based on the trajectory and the at least first angular datum.
