Abstract
A method of detecting weather using a weather radar onboard an aircraft. A range is selected at which weather is to be detected. A tilt angle of the weather radar is changed to detect weather below an altitude of the aircraft at a selected range when the selected range includes a maritime environment.
Claims20
A method of detecting weather using a weather radar onboard an aircraft at a location, the method comprising:
- receiving an indication of the location or area near the location of the weather radar;
- and
- changing a tilt angle of the weather radar to detect weather below an altitude of the aircraft at a selected range when the indication is associated with a maritime environment, wherein the tilt angle is changed to a lower angle than the tilt angle used for the selected range in a continental environment.
A method of detecting weather events using a weather radar in an aircraft, the method comprising:
- receiving an indication of a location of the weather radar;
- and
- adjusting a tilt angle of the weather radar downward from a non-maritime tilt position to a maritime tilt position in response to the indication identifying the location as being associated with a maritime environment.
An airborne weather radar system that detects weather events in a location, comprising:
- a radar antenna, disposed upon an aircraft, and configured to detect weather events at a selected range;
- and
- a processor for setting a tilt angle of the radar antenna, the tilt angle being automatically lowered with respect to the tilt angle for a continental environment in response to the location being in a maritime environment.
