Abstract: Systems and methods for displaying a location reference indicator (LRI) associated with an ownship icon are provided. In various embodiments, an airport moving map (AMM) is displayed, and the ownship icon is displayed in the AMM, where the ownship icon represents the ownship. A degree of zoom of the AMM is determined. In response to a determination that the degree of zoom is not within a range of center referenced threshold values, a first LRI is displayed that indicates that the icon representing the ownship is not to scale with other objects displayed in the AMM. In response to a determination that the degree of zoom is within the range of center referenced threshold values, a second LRI is displayed.

Abstract: In some examples, a processor is configured to control a ground obstacle collision alerting system of an aircraft to deactivate delivery of ground obstacle collision alerts in response to determining the aircraft is in a designated ground area. In some examples, the processor is configured to determine the aircraft is in the designated ground area based on user input, based on a geographic location of the aircraft, or both. The processor is further configured to control the ground obstacle collision alerting system to automatically reactivate the delivery of the ground obstacle collision alerts in response to determining the aircraft is outside of the designated ground area. In some examples, the processor is configured to determine the aircraft is outside of the designated ground area based on a geographic location of the aircraft, a ground speed of the aircraft, or both.

Abstract: Systems and methods for identifying ownship deviation from assigned taxi-clearance in the area of taxiway intersection. An exemplary system provides alerts in the event of a significant deviation from the assigned clearance, but does not give unwanted alerts when the flight crew is performing normal turning maneuvers in the area of an intersection.

Abstract: Systems and methods for alerting a flight crew if a taxiing collision condition exists. An exemplary system on a host vehicle determines one or more first protection zones around other vehicles on the ground based on the received information about the other vehicles, determines a second protection zone around the host vehicle based on the stored information about the host vehicle and the sensor information and generates an alert, if any of the first protection zones occupies at least a portion of the same geographic area as the second protection zone. The received information includes position, ground speed, vehicle type information and heading or track information. The protection zones include a width dimension that is based on vehicle size information, a base length dimension that is based on the size information, and a variable component of the length dimension that is based on the ground speed.
