First Claim
1. A system for displaying aeronautical information, said system comprising:
- a central processing unit;
a memory coupled to said central processing unit; and
a display screen coupled to said central processing unit,said central processing unit being configured for executing the steps of;
1) receiving, from a user, a user-specified upper-threshold altitude;
2) receiving altitude-related information regarding one or more targets;
3) using said altitude-related information to identify one or more targets that have an altitude that is greater than said user-specified upper-threshold altitude; and
4) withholding from display on said display screen one or more of said one or more targets identified in said Step 3,wherein said central processing unit is further configured for;
displaying said user-specified upper-threshold altitude on said display screen;
displaying a lower-threshold altitude on said display screen;
displaying a current filtering mode on said display screen, wherein said current filtering mode is selected from a group consisting of;
look-up mode, look-down mode, and look level mode.

Abstract
A system and method for filtering various targets (such as ground vehicles, stationary objects, and aircraft) from display on a display screen within the cockpit of an “Own Ship” aircraft. The system and method withhold from display any non-exempt targets that have an altitude that is either: (1) greater than an upper-threshold altitude; or (2) less than a lower-threshold altitude. The upper-threshold altitude and the lower-threshold altitude may be set to user-specified, customized values as desired to accommodate current flying conditions. In addition, the system and method may also be configured to operate in a plurality of operating modes, each of which features a different upper threshold altitude/lower threshold altitude combination. The system and method are preferably configured to reset certain threshold altitudes to pre-defined default altitudes in response to the aircraft landing.

11. A system for displaying aeronautical information, said system comprising:
-
a central processing unit; a memory coupled to said central processing unit; and a display screen coupled to said central processing unit, said central processing unit being configured for executing the steps of; 1) receiving, from a user, a user-specified lower-threshold altitude; 2) receiving altitude-related information regarding one or more targets; 3) using said altitude-related information to identify one or more targets that have an altitude that is less than said user-specified lower-threshold altitude; and 4) withholding from display on said display screen one or more of said one or more targets identified in said Step 3, wherein said central processing unit is further configured for; receiving an exempt target designation identifying at least one exempt target that is not to be withheld from display on said display screen based on a relationship between said user-specified lower-threshold altitude and an altitude of said exempt target; and in response to said exempt target being detected by said system, displaying said exempt target on said display screen regardless of whether an altitude of said exempt target is greater than, less than, or equal to said user-specified lower-threshold altitude. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
