Quiet mode operation for cockpit weather displays
First Claim
1. A method for operating threat-warning display for a vehicle comprising:
- obtaining real-time threat information from a source of threat information, calculating the present position, heading and speed of the vehicle, calculating whether at the present position, heading, and speed, the vehicle will encounter a threat in a predetermined period of time, and displaying the threat on a display screen only when the vehicle will encounter the threat within the predetermined period of time.

Abstract
An airborne computer is linked to a ground-based or satellite-based supplier of weather data that is geographically referenced. The computer retrieves the weather data on a regular cycle but does not display the data. The computer also has access to the aircraft'"'"'s state, i.e., position, altitude, speed, and intended route. Algorithms within the computer combine the present and estimated future positions of the aircraft with the weather data, and create an alert to the crew if a threat is detected. When a threat is detected, the weather display is activated to draw the attention of the crew to the threat.

11. A method for operating an aircraft cockpit weather threat display system in an unobtrusive manner, having a source of real-time weather data including the geographical position of weather of a level constituting a threat to the aircraft, a source of flight data including present position, speed, and planned course of the aircraft, a processor for processing weather and flight data, and a display for selectively displaying weather threats, comprising
using the flight data to calculate the position of the aircraft over a predetermined time, comparing the position of the aircraft with the real time weather data to determine whether the aircraft will encounter weather which is a threat to the aircraft, and displaying the threat on a display only when the vehicle will encounter the threat within the predetermined period of time.
