Aspects of this present disclosure relate to systems and methods for dynamically moving graphical elements of a user interface of a flight control system. In one, a method is disclosed comprising: determining aircraft authority limits based on at least one state signal indicating an aircraft state, wherein the aircraft authority limits indicate an extent to which one or more control signals can command the aircraft; determining one or more proximities between the aircraft state and the determined aircraft authority limits; and automatically moving the graphical elements of the user interface to one or more positions on the user interface based on the determined one or more proximities.

An electrical propulsion system comprises an inverter, an electrical motor assembly, an assembly, and a rotor position sensor. The inverter comprises a printed circuit board assembly (PCBA). The electrical motor assembly comprises a stator and a rotor. The assembly is configured to rotate a propeller and comprises a moving component and a stationary component. The rotor position sensor comprises at least one sensor coupled to the PCBA, and a magnet located on the moving component. The at least one sensor is configured to detect a magnetic field of the magnet through the stationary component.
