The vertical resolution and/or vertical accuracy of topographic elevation data in the vicinity of an aircraft runway is adjusted by obtaining local topographic data, producing a first elevation value for a query location. A processor receiving the first elevation value calculates a plane equation based on a predetermined standard model adapted to geometrically conform to the aircraft runway, thereby producing a second elevation value for the query location. The processor selectively uses the first and second elevation values to generate an adjusted elevation value provided to the terrain avoidance and warning system.
飞行器跑道附近的地形高程数据的垂直分辨率和/或垂直精度通过以下方式来调整:获得本地地形数据,产生查询位置的第一高程值。接收第一高程值的处理器基于适合于在几何上符合飞行器跑道的预定标准模型来计算平面方程,从而产生查询位置的第二高程值。处理器选择性地使用第一和第二高程值来生成提供给地形避开和警告系统的调整后的高程值。
