1. A method for aircraft operation comprising, while operating an aircraft in a flight mode:
- during a first time interval, at a downward proximity sensor of the aircraft, sampling a first downward proximity measurement, wherein the downward proximity sensor is oriented substantially downward with respect to an aircraft vertical axis;
based on the first downward proximity measurement, determining a first ground clearance between the aircraft and a floor below the aircraft;
during the first time interval, at an upward proximity sensor of the aircraft, sampling a first upward proximity measurement, wherein the upward proximity sensor is oriented substantially upward with respect to the aircraft vertical axis;
based on the first upward proximity measurement, determining a first ceiling clearance between the aircraft and a ceiling above the aircraft, wherein the first ceiling clearance is greater than zero;
during a second time interval after the first time interval, at the upward proximity sensor, sampling a second upward proximity measurement;
based on the second upward proximity measurement, determining a second ceiling clearance between the aircraft and the ceiling;
based on the first and second ceiling clearances, determining a ceiling clearance change;
based on the ceiling clearance change and the first ground clearance, determining a second ground clearance between the aircraft and the floor; and
controlling flight of the aircraft based on the second ground clearance.

Abstract
An aerial system, preferably including one or more proximity sensors, such as sensors arranged in opposing directions. A method for aerial system operation, preferably including: determining a set of sensors; sampling measurements at the set of sensors; localizing the aerial system based on the measurements, such as to determine one or more obstacle clearances; and controlling system flight, such as based on the clearances.

12. A method for aircraft operation comprising, while operating an aircraft in a flight mode between a first obstacle and a second obstacle:
-
during a first time interval, at a first proximity sensor of the aircraft, sampling a first proximity measurement indicative of aircraft proximity to the first obstacle, wherein the first proximity sensor is oriented in a first direction; based on the first proximity measurement, determining a first obstacle clearance between the aircraft and the first obstacle; during a first time interval, at a second proximity sensor of the aircraft, sampling a second proximity measurement indicative of aircraft proximity to the second obstacle, wherein the second proximity sensor is oriented in a second direction substantially different from the first direction; based on the second proximity measurement, determining a second obstacle clearance between the aircraft and the second obstacle, wherein the second obstacle clearance is greater than zero; during a second time interval after the first time interval, at the second proximity sensor, sampling a third proximity measurement indicative of aircraft proximity to the second obstacle; based on the third proximity measurement, determining an updated second obstacle clearance; based on the second obstacle clearance and the updated second obstacle clearance, determining a second obstacle clearance change; based on the second obstacle clearance change and the first obstacle clearance, determining an updated first obstacle clearance; and controlling flight of the aircraft based on the updated first obstacle clearance. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
