A dynamic wake avoidance system utilizes aircraft and atmospheric parameters readily available in flight to model and predict airborne wake vortices in real time. A novel combination of algorithms allows for a relatively simple yet robust wake model to be constructed based on information extracted from a broadcast. The system predicts the location and movement of the wake based on the nominal wake model and correspondingly performs an uncertainty analysis on the wake model to determine a wake hazard zone (no fly zone), which comprises a plurality of “wake planes,” each moving independently from another. The system selectively adjusts dimensions of each wake plane to minimize spatial and temporal uncertainty, thereby ensuring that the actual wake is within the wake hazard zone. The predicted wake hazard zone is communicated in real time directly to a user via a realistic visual representation. In an example, the wake hazard zone is visualized on a 3-D flight deck display to enable a pilot to visualize or “see” a neighboring aircraft as well as its wake. The system substantially enhances the pilot's situational awareness and allows for a further safe decrease in spacing, which could alleviate airport and airspace congestion.

An airborne obstacle detector for a helicopter includes a visual display, a GPS receiver and an altimeter for indicating the position and course of an aircraft. A computer provides moving map data indicative of a topography of an area which surround the position of the aircraft. The computer determines a first hazard zone within a first preselected distance from the aircraft and generates a first color display of a first hazard zone based on the moving map data. The computer also detects a more danger zone within a second preselected distance from the aircraft which is less then the first preselected distance and generates a second color display of the more dangerous zone. A detector then senses a physical obstacle which is within a third preselected distance from the aircraft which is less than the first preselected distance from the aircraft and sends a signal to an alarm. The alarm then produces a series of audible clicks which increase in frequency and / or volume as the aircraft approaches the obstacle. A mute subsystem, a visual alarm in place of a muted audio signal and a mute override are also disclosed.
