I'm confused... Please interpret this note for me... https://aeronav.faa.gov/d-tpp/1906/05901R29.PDF On the RNAV 29 to Burlington WI, the following note applies: "Straight-in and Circling Rwy 29 NA at night." What else is there other than a straight in or circling? Does this note mean that the procedure is not authorized at night? Please help unconfuse me.
