Systems and methods for the co-location of high-maintenance air data system components into one LRU are disclosed. In at least one embodiment, an air data sensing line-replaceable unit (LRU) comprises at least one pressure sensor and at least one probe or port coupled to the at least one pressure sensor. The at least one probe or port conduits air located outside the air data sensing LRU to the at least one pressure sensor. Further, the at least one probe or port and the at least one pressure sensor are connected to each other by a permanent connection.
