Power line detection system

In an existing transmission line complex including at least one tower and at least one transmission line, the improvement comprising a detection system, said detection system including:

• at least one radio-frequency (RF) transmitter mounted on said at least one transmission line;
• a RF receiver located on board an aircraft wherein said RF receiver is tuned to receive a transmission from said at least one RF transmitter;
• and
• wherein said RF receiver comprising:
• a RF antenna;
• a first receiver channel to receive a first frequency from said RF antenna;
• a second receiver channel to receive a second frequency from said RF antenna;
• and
• a first comparator to compare signals from said first receiver channel and said second receiver channel wherein said first comparator sends a signal to a display and alarm system after comparing the signals from the first and second receiver channels
• the display and alarm system located on-board said aircraft wherein said display and alarm system is triggered by said RF receiver when said RF receiver receives a transmission from said at least one RF transmitter, said display and alarm system comprising:
• a first display to indicate a Dower line altitude signal and identification number of said at least one RF transmitter;
• a barometric pressure corrected altimeter producing an aircraft altitude signal;
• a second display to indicate said aircraft altitude signal;
• a comparator to compare said aircraft altitude signal with said power line altitude signal;
• a third display to indicate the difference between said aircraft altitude signal and said power line altitude signal plus a margin of error;
• and
• an audio and visual alarm that receives signals from said comparator, wherein said audio and visual alarm is triggered when said aircraft altitude is less than said power line altitude plus said margin of error.
