Portable meteorological information system
First Claim
1. An apparatus useable in combination with a ground-based weather station, wherein the ground-based station is at an airport runway, the station transmitting signals conveying raw data concerning meteorological conditions at the station, said apparatus comprising:
- a signal receiver for receiving the transmitted signals;
a central processing unit for calculating derived meteorological information at least in part from the raw meteorological data accepted from said signal receiver;
means for inputting into said central processing unit physical data respecting the runway, said physical data selected from the group of site-specific data consisting of runway length, runway altitude, and runway heading; and
means for displaying the raw meteorological data and said derived meteorological information.

Abstract
A meteorological information system useable by aircraft pilots and others. A receiver-calculator unit receives raw meteorological data and site-specific physical data from a ground-based weather station having a signal transmitter for broadcasting signals conveying data about weather conditions at the station. The transmitted raw data signals are received by the receiver-calculator unit in the aircraft. The receiver-calculator unit may feature an input with which the operator inputs information about the physical character, such as the heading, of the runway of interest. The receiver-calculator unit processes both received raw weather data and received site-specific physical data, and/or operator-input data, to derive additional meteorological information. The raw and derived weather conditions information is displayed by the unit to be available to the aircraft pilot during landing or take-off maneuvers. Optionally, the apparatus uses known algorithms for determining aircraft performance characteristics to process raw and derived weather and site-specific data to determine the relative safety of proposed aircraft maneuvers, such as take-off.
