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.

Altitude range filter for cockpit traffic display

The present invention provides an aircraft navigational system including a graphical user interface that is capable of displaying navigational information in a split-screen format. The split-screen format includes displaying multiple graphical user panels, each depicting different traffic information. For example, one of the panels displays a plurality of air traffic symbols corresponding to airborne obstacles and another of the panels simultaneously displays ground traffic symbols representing ground obstacles. The obstacles can include other aircraft in the air and on runways as the pilot's aircraft approaches for a landing. The navigational system also is capable of switching between a single graphical user panel and multiple panels in response to a triggering event, such as a change in the course of the aircraft.

A communications system provides subfleet calls for both voice and data communications using a secondary identification (301, 303, 305, 307, 309) incorporating a plurality of subfleets in a hierarchical arrangement. A message including the secondary identification (301, 303, 305, 307, 309) is transmitted to a communication unit (117) having a stored secondary identification (301, 303, 305, 307, 309). If the transmitted secondary identification sufficiently matches the stored secondary identification, the communication unit (117) responds to the instructions in the transmitted message.
