Abstract
Abstract A method for providing real-time weather and other information about an airport to an aircraft. The method comprises the steps of generating a signal representing instantaneous weather information, determining a real-time weather information value from the instantaneous weather information signal over a predetermined time interval, generating an address signal representing the real-time weather information value, storing a plurality of signals representing real-time weather information messages, generating one of the message signals corresponding to the real-time weather information value in response to the address signal, and transmitting the message signal to a receiver on the aircraft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A method of transmitting a plurality of types of real-time weather information to a remotely located receiver comprising the steps of: a. generating a signal representing instantaneous weather information; b. determining a real-time weather information value from said instantaneous weather information signal over a predetermined time interval; performing said steps (a) and (b) for each one of said types of real-time weather information in sequence; c. generating an address signal representing said real-time weather information value; d. storing a plurality of signals representing real-time weather information messages; e. generating the one of said message signals corresponding to the real-time weather information value in response to said address signal; f. transmitting said one message signal to the receiver; and performing steps (c) through (f) for each one of said types of real-time weather information in sequence.
Claim 2
Independent Claim
135 words
A method of transmitting a plurality of types of real-time weather information to a remotely located receiver comprising the steps of: a. generating a signal representing instantaneous weather information; b. determining a real-time weather information value from said instantaneous weather information signal over a predetermined time interval; performing said steps (a) and (b) for each one of said types of real-time weather information in sequence; c. generating an address signal representing said real-time weather information value; d. storing a plurality of signals representing real-time weather information messages; e. generating the one of said message signals corresponding to the real-time weather information value in response to said address signal; f. transmitting said one message signal to the receiver; and performing steps (c) through (f) for each one of said types of real-time weather information in sequence.
Claim 3
Dependent Claim
27 words
The method according to claim 1 wherein said step (b) includes averaging said weather information signal over said predetermined time interval for obtaining said real-time information signal.
Claim 4
Dependent Claim
27 words
The method according to claim 1 including the step of generating an activation signal and wherein said step (c) is performed in response to said activation signal.
Claim 5
Dependent Claim
21 words
The method according to claim 1 wherein said step (a) includes periodically storing the present value of said instantaneous weather information.
Claim 6
Dependent Claim
46 words
The method according to claim 4 including the step of comparing said present value of said instantaneous weather information signal with the value of the last stored value of said instantaneous weather information signal and generating a malfunction indication if the difference exceeds a predetermined value.
Claim 7
Independent Claim
185 words
A method for transmitting real-time weather and other information to an airplane having a radio receiver comprising the steps of: a. generating a plurality of signals representing instantaneous weather information including a temperature signal, a wind speed signal, a wind direction signal and a barometric pressure signal; b. determining a real-time weather information value for each of said plurality of weather information signals over individual predetermined time intervals; performing said steps (a) and (b) for each of said weather information signals in sequence; c. generating a plurality of address signals each representing one of said real-time weather information values; d. storing a plurality of signals representing real-time weather information messages; e. generating the one of the plurality of message signals corresponding to each one of said real-time weather information values in response to said address signals; and f. transmitting said message signal to the radio receiver whereby said real-time weather information signals are audibly reproduced to provide the pilot with temperature, wind speed and direction and barometric pressure information; and performing said steps (c) through (f) for each of said weather information signals in sequence.
Claim 8
Independent Claim
185 words
