This is an obsoleted category in the CPC patent technology category system. It had to do with airplanes and helicopters, and the phrase "lift being provided.": [1]
This category was deleted around May 1, 2017: [2] It seems to have been five levels down in the tree, and CPC B64C2700/627 was its immediate parent. Patents with this assignment were reassigned numbers in the B64C tree. Oddly the deletion document doesn't lay out what the codes meant; what phrase or tree applied.
