Abstract: A method, apparatus and system for monitoring an emergency frequency at a ground station for detection of an emergency signal and, upon detecting an emergency signal, determining whether the emergency signal represents an emergency event. If an emergency event is detected, the emergency event is reported. Determining whether the emergency signal represents an emergency event may include testing validity of the emergency signal to eliminate false positives. Reporting the emergency event may include sending an emergency event message to a remote server. The emergency event message may include time information and signal strength information associated with the detected emergency event and location information associated with the ground station.

Abstract: A method and apparatus for automatically providing advisories to pilots in a monitored airspace comprises monitoring weather conditions and air traffic in an airspace and then generating and broadcasting advisories over a radio channel in response to relevant air traffic conditions. Advisory lengths are sized based on the volume of communications on the common traffic advisory frequency. An airspace model, made up of a multitude of constantly updated records, is used to keep track of important flight information and weather conditions. A monitoring CPU, accessing the airspace model, creates the advisory messages based upon hazard criteria, guidelines, airport procedures and other relevant air traffic data.

Abstract: A method for automatically providing weather advisories for an airport to pilots comprises monitoring weather conditions at the airport and then generating weather advisories in response to these weather conditions. The broadcast traffic on a common traffic advisory channel is also simultaneously monitored and then menus providing for selectable weather advisories and radio check options are broadcast to the pilots. The weather advisories or radio check can then be selected by the pilot by clicks of their transmit button. The time spacing between the menus is adaptively changed in response to traffic on the common traffic advisory frequency. Also, the length of the weather advisories is also changed in response to this traffic. The radio check option is provided automatically by first confirming selection of the radio check option and then allowing the broadcaster to broadcast a short message which is recorded by the system and then rebroadcast.

Abstract: An automated transceiver is adapted to monitor a frequency of interest. In response to receiving some predetermined protocol, it becomes activated and records the next transmission on the frequency. The transceiver then rebroadcasts the recorded transmission. In this way, a radio operator can be assured that the transceiver is operating when the rebroadcasted transmission is received. If the transmission from the device is an acceptable quality, there is an assurance that the transceiver is operating properly since, to receive the rebroadcasted transmission, both the transmitter portion must operate to transmit the message to the inventive radio check device, and the receiver portion of the transmitter must be operational to receive the rebroadcasted message from the system. The remote operator need not rely on the subjective determination of another. Further, the participation of another person is not required.
