Thermal imaging systems can typically get better visibility through the moisture. I do agree, however, this certainly won’t be replacing an ILS any time soon.

This system would be an excellent input to the pilot for managing glide path when the ILS system is inoperative. The PAPI (precision approach path indicator) light system also provides guidance but it’s not a very tight path.
