A System for In-Flight Weather Mapping Using Existing Ground Based Facilities 981211
In flight weather mapping remains an area out of the reach of many operators of single and light twin engine aircraft. Those systems that exist tend to be heavy, costly or both. Data link systems that transmit the data from ground based weather sensors to the aircraft are in work, but require dedicated ground based transmitters and special receivers in the aircraft.
This paper will propose a simple method of transmitting ground based weather radar data to the aircraft. The system sends image data over the existing voice channel of VOR navigation stations. These transmitters already installed and require only the addition of inexpensive equipment. The aircraft needs only a processor and display unit that could cost less than $1000.
