This disclosure is directed to weather radar configured to act as a communication device to allow real time data communication. This disclosure describes using weather radar on board aircraft as a high bandwidth X-band radio for communication. The X-band weather radar is used for receiving flight related data and weather-related data while still acting as a weather radar. As the weather radar system is already present on most commercial aircraft, there is no requirement for additional hardware, devices or equipment onboard the aircraft to meet the data communication needs. An airport may install an X-band data transmitter to broadcast digital data received from detection systems at or near an airport such as an Automated Weather Observing System (AWOS), predictive wind shear (PWS) and bird strike warning systems.

1. A method comprising: transmitting, by a weather radar antenna of a weather radar system of an aircraft, radar signals;receiving, by the weather radar antenna of the weather radar system, reflected radar signals;receiving, by the weather radar antenna of the weather radar system, an X-band carrier
1. A method comprising: transmitting, by a weather radar antenna of a weather radar system of an aircraft, radar signals;receiving, by the weather radar antenna of the weather radar system, reflected radar signals;receiving, by the weather radar antenna of the weather radar system, an X-band carrier signal, wherein the X-band carrier signal comprises a broadcast signal from an omni-directional X-band transmitting antenna and includes a digital data stream, wherein the digital data stream is separate from the reflected radar signals;converting, by the weather radar system, the digital data stream into an alert signal; andoutputting, to an operator of the aircraft and by the weather radar system, a representation of the alert signal. 2. The method of claim 1, wherein the digital data stream includes first information and second information, and the first information and the second information comprise one or more of lightning location, runway wind speed, runway wind direction, precipitation, visibility, temperature, air pressure, airborne aircraft location coordinates, aircraft taxi location coordinates, bird flock location coordinates, wind shear area coordinates, or ground vehicle location coordinates. 3. The method of claim 1, further comprising: performing, by the weather radar system, weather radar functions while receiving the digital data stream. 4. The method of claim 1, wherein outputting, by the weather radar system, the representation of the alert signal comprises outputting the alert signal to a multi-function display (MFD). 5. The method of claim 1, further comprising: outputting the representation of the alert signal as an auditory message. 6. The method of claim 1, wherein the weather radar system receives the digital data stream from an airport X-band data transmitter. 7. The method of claim 1, wherein outputting, by the weather radar system, the representation of the alert signal comprises outputting the alert signal to an integrated display unit of the weather radar system. 8. A system for data communication, the system comprising: a data communication interface configured to receive first information from a first airport detection system;an X-band data conversion unit communicatively coupled to the data communication interface and configured to convert the first information from the first airport detection system to first digital data on an X-band carrier signal, wherein to convert the first information, the X-band data conversion unit modulates the X-band carrier signal to load the first digital data onto the X-band carrier signal;an omnidirectional antenna; andan X-band data transmitter configured to receive the first digital data from the X-band data converter and transmit broadcast the first digital data on the X-band carrier signal via the omnidirectional antenna. 9. The system of claim 8, wherein the X-band data conversion unit is further configured to convert second information from a second airport detection system to second digital data on the X-band carrier signal. 10. The system of claim 9, wherein the first airport detection system and the second airport detection system comprise one or more of: air traffic control (ATC) radar, airport surveillance radar (ASR), terminal Doppler weather radar (TDWR), airport surface detection system, avian radar system, predictive wind shear system (PWS), Automated Weather Observing System (AWOS) or bird strike prevention system. 11. The system of claim 9, wherein the first information and the second information comprise one or more of lightning location, runway wind speed, runway wind direction, precipitation, visibility, temperature, air pressure, airborne aircraft location coordinates, aircraft taxi location coordinates, bird flock location coordinates, wind shear area coordinates, or ground vehicle location coordinates. 12. The system of claim 8, wherein the omnidirectional antenna is on an airport and the X-band data transmitter is configured to transmit the first digital data from the airport to an aircraft within receiving distance of the X-band data transmitter. 13. The system of claim 12, wherein the receiving distance of the X-band data transmitter is approximately ten nautical miles. 14. A device installed in an aircraft comprising: an X-band transmitting antenna configured to transmit radar signals;an X-band receiving antenna configured to receive reflected radar signals and an X-band carrier signal, wherein: the X-band carrier signal comprises a broadcast signal from an omni-directional X-band transmitting antenna;the X-band carrier signal includes a digital data stream, andthe X-band carrier signal is separate from the reflected radar signals;X-band data receiver circuitry configured to extract a digital data stream from the X-band digital data signal and convert the digital data stream into an alert signal; andan output device configured to output the alert signal to an operator of the aircraft. 15. The device of claim 14, further comprising: an integrated display unit, wherein the integrated display unit is configured to receive the alert signal at the output device and present a representation of the alert signal. 16. The device of claim 14, wherein: the alert signal is compatible with a multi-function display (MFD),the MFD is configured to receive the alert signal at the output device, andthe alert signal causes the MFD to present a representation of the alert signal. 17. The device of claim 14, wherein the output device is configured to output the alert signal in a format compatible with an auditory message. 18. The device of claim 14, wherein the X-band receiving antenna is an airborne weather radar antenna and the X-band data receiver circuitry includes computer-readable medium storing instructions that provide the capability for the X-band receiver circuitry to extract the digital data stream from the X-band data signal. 19. The device of claim 14, wherein the X-band receiving antenna comprises an omnidirectional X-band receiving antenna. 20. The device of claim 14, wherein the digital data stream includes first information and second information and the first information and the second information comprise one or more of lightning location, runway wind speed, runway wind direction, precipitation, visibility, temperature, air pressure, airborne aircraft location coordinates, aircraft taxi location coordinates, bird flock location coordinates, wind shear area coordinates, or ground vehicle location coordinates.
