Systems and methods for applying a movable notch filter in flight control of EVTOL aircraft

An aircraft, comprising:

• at least one propeller;
• at least one inertial sensor;
• a second sensor;
• at least one processor configured to:
• receive first sensor data from the at least one inertial sensor of the aircraft, wherein the first sensor data is indicative of a state of the aircraft;
• receive second sensor data from the second sensor, the second sensor comprising at least one of an airspeed sensor indicating an airspeed of the aircraft or a propeller speed sensor indicating a propeller speed of the at least one propeller of the aircraft;
• determine the state of the aircraft based on the first sensor data, wherein:
• determining the state of the aircraft comprises filtering aircraft state measurements using at least one filter parameter to lessen influence of propeller vibrations on at least one aircraft signal;
• and
• the at least one filter parameter is dynamically determined based on the second sensor data while the aircraft is in flight;
• and
• control the aircraft based on a pilot input command and the determined state of the aircraft.
