Abstract
A terrain awareness and warning system (“TAWS”) provides input to a terrain alert (“TA”) processor from at least one real-time aircraft system or sensor and a source of terrain data; the processor determines a terrain clearance surface and a terrain airspace alert surface, and if one surface penetrates the other, the processor generates an alert signal and provides an alert signal to a crew alerting system. The two surfaces are determined by the processor by executing an algorithm(s) embedded in software containing the disclosed embodiments and methods. At least one criterion used to define an aircraft terrain alert surface is programmed to include real-time and/or static input factor data provided by at least one system or sensor input from an aircraft. Such input factor could be used to define a terrain clearance surface.
