Automatic weather monitoring and adaptive transmitting system
First Claim
1. A method for automatically providing weather advisories to pilots for an airport, comprising:
- automatically determining weather conditions at the airport;
periodically transmitting the weather advisories in response to the weather conditions on a radio frequency assigned to the airport even when no broadcasts on the frequency from other sources are detected;
monitoring the radio frequency for broadcasts from other sources; and
adaptively changing a period between successive transmissions on the radio frequency of the weather advisories in response to a frequency of the broadcasts from other sources.

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.

4. A method for providing airport weather information to pilots using an automatic weather transmission system, the method comprising:
-
determining weather conditions; transmitting periodic messages announcing a presence of the system and instructions for use of the system on a radio frequency assigned to the airport; responding to pilot requests to access the system by transmitting on the radio frequency information concerning the determined weather conditions; and preventing transmission on the radio frequency of the periodic messages to avoid interfering with transmission from other sources on the radio frequency. - View Dependent Claims (5, 6, 7, 29, 30, 31, 32, 33)

8. A method for automatically providing weather advisories for an airport to pilots using an automatic weather monitoring system, the method comprising:
-
determining weather conditions at the airport; generating the weather advisories in response to the weather conditions; monitoring broadcasts from other sources on a common traffic advisory frequency of the airport; determining existence of a converstation by the other sources on the frequency; broadcasting on the advisory frequency one of a message containing instructions on accessing the system to obtain the weather advisories or the weather advisory; and delaying the broadcasts for a predetermined time period after the end of a conversation from the other sources. - View Dependent Claims (9)

10. A method for providing weather advisories to pilots for an airport using an automatic weather monitoring system, the method comprising:
-
automatically determining weather conditions; periodically broadcasting a menu on a radio frequency assigned to the airport, the menu including a weather advisory option being selectable by broadcasting a predetermined protocol on the radio frequency; detecting broadcast of the predetermined protocol on the radio frequency; and broadcasting the weather advisory on the radio frequency in response to detection of the predetermined protocol. - View Dependent Claims (11, 12, 13, 14, 21, 22)

15. A device for broadcasting weather advisories to pilots, comprising:
-
an automatic weather station for generating weather data indicative of weather conditions; a central processing unit for periodically generating synthesized voice menus, and for selectively generating weather advisories from the weather data in response to a carrier detect signal; and a transceiver for generating the carrier detect signal in response to detection of broadcasts on a radio frequency assigned to the device from other sources, and for broadcasting on the radio frequency the periodic synthesized voice menus and weather advisories. - View Dependent Claims (16, 17, 18, 19, 20, 27, 28)

36. A method for providing information to pilots for an airport, the method comprising:
-
periodically broadcasting a menu on a radio frequency assigned to the airport including information categories, different ones of the information categories being selectable by broadcasting corresponding predetermined protocols on the radio frequency; detecting broadcast of the predetermined protocols on the radio frequency; broadcasting information on the radio frequency corresponding to a selected one of the information categories indicated by the received one of the predetermined protocols; and preventing broadcast on the radio frequency of the menu in response to a concurrent broadcast on the radio frequency from another source. - View Dependent Claims (37, 38, 39)
