20150364047 | TERRAIN AWARENESS SYSTEM WITH OBSTRUCTION ALERTS - Current TAWS systems generally do not provide alerts based on structures or wire obstacles. Such structures and wire obstacles include transmission and electrical wires, and power lines, bridges, and buildings. The current system allows just such alerting. Such alerts are particularly useful for helicopter aircraft, which commonly fly at heights where such structures and obstacles are present near the normal flying altitude of the aircraft. Certain implementations of the system and method include a method of creating an obstacle for use in a terrain awareness warning system, including: receiving data about a first terminus of an obstacle; receiving data about a second terminus of the obstacle; constructing a virtual volume about the first and second termini and a volume therebetween; and storing the virtual volume, whereby a database may be constructed of virtual volumes for use in addition to terrain information to provide alerting on obstacles for an aircraft. | 12-17-2015 |
20130345909 | AIRCRAFT HOVER SYSTEM AND METHOD - An aircraft hover system for enabling an aircraft to hover at a target spatial location represented by GPS location coordinates. The hover system includes a display screen rendering a display including live video feed of the terrain below the airborne aircraft, a first mark overlaying the video feed, the first mark representing the current position of the aircraft relative to the terrain, and a perimeter surrounding the first mark, the portion of the terrain within the perimeter being substantially magnified compared to that of the terrain outside of the perimeter. The hover system is configured such that, as the aircraft approaches the target spatial location, the distance between the first mark and a second mark on the display gradually decreases until and finally the first and second marks coincide; the second mark representing the target spatial location. | 12-26-2013 |
20130190951 | PRESSURE ALTITUDE STABILIZATION - A method and apparatus is provided for determining the altitude of an aircraft. In accordance with the method, Global Positioning Satellite (GPS) data is received from a plurality of GPS satellites and a GPS altitude value is determined from the GPS data. In addition, a pressure altitude value is determined. An altitude difference is determined between the GPS altitude value and the pressure altitude value. At least one of the GPS altitude value and the pressure altitude value is adjusted using the altitude difference. | 07-25-2013 |
20120203997 | INTEGRITY MONITORING - Systems and methods are described here to provide a degree or level of certification to a resident application such as an operating system, e.g., Linux®. In a Linux® implementation, the operating system provides a robust environment including many seasoned communication stacks, e.g., TCP/IP, USB, and the like. However, Linux® is not certified to the level necessary to be a part of many avionics applications. To eliminate the need to certify all of such an operating system, such certification being highly costly, the avionics application itself may be protected so that the operating system cannot alter the application's operating environment, e.g., application code and data, once the application is loaded and running. In this case, only the application requires certification at the highest level, and not the operating system such as Linux®. | 08-09-2012 |

The hover system is configured such that, as the aircraft approaches the target spatial location, the distance between the first mark and a second mark on the display gradually decreases until and finally the first and second marks coincide; the second mark representing the target spatial location. | 01-05-2012 |
20110276201 | TAWS WITH ALERT SUPPRESSION - An aircraft terrain awareness warning system is disclosed that includes an interface for entering flight plan details of an aircraft including at least one waypoint. The terrain awareness warning system is configured such that potential-terrain-collision alerts are suppressed in the aircraft during landing operations performed at waypoints associated with landing zones. | 11-10-2011 |
