Abstract
A control system for providing electrical power to an electronic flight bag device on an aircraft. The control system including a power switching component coupled to a plurality of power sources and at least one electronic flight bag device. The power switching component is operative and configured to selectively apply electrical power from at least one of the plurality of power sources to the at least one electronic flight bag device based upon a condition of the aircraft.
Claims20
A control system for providing electrical power to an electronic flight bag device on an aircraft, the control system comprising a power switching component coupled to a plurality of power sources and at least one electronic flight bag device
- wherein the control system is coupled to the at least one electronic flight bag device by a primary feed;
- wherein the control system is coupled to the at least one electronic flight bag device by an auxiliary feed;
- and
- wherein the power switching component is operative and configured to selectively apply electrical power from at least one of the plurality of power sources based upon a condition of the aircraft.
An electronic flight bag control system comprising:
- a power switching component;
- a primary feed line-in coupling a primary power source to the power switching component;
- an auxiliary feed line-in coupling an auxiliary power source to the power switching component;
- a primary feed coupling at least one electronic flight bag device to the power switching component;
- an auxiliary feed coupling the at least one electronic flight bag device to the power switching component;
- wherein the power switching component is operative and configured to selectively apply electrical power from at least one of the power sources from the plurality of power sources to the at least one electronic flight bag device based upon a condition of the aircraft.
A method for providing electrical power to an electronic flight bag on an aircraft comprising the steps:
- providing a power switching component coupled to a plurality of power sources;
- coupling at least one electronic flight bag device to each of the plurality of power sources via the power switching component through a primary feed and an auxiliary feed;
- determining if the aircraft is in a predetermined condition;
- applying electrical power via the power switching component from one of the plurality of power sources to the at least one electronic flight bag device when the aircraft is determined to be in the predetermined condition;
- and
- applying electrical power via the power switching component from at least two of the plurality of power sources to the at least one electronic flight bag device when the aircraft is determined not in the predetermined condition.
