Standard noaid aerodrome procedures - the fact that it's unlicenced doesn't really matter - the aerodrome either it has an IAP or it doesn't. In which case, in VMC - IFR aircraft can conduct a visual approach under the requirements (descend below LSALT within the circling area and intercept the normal descent profile for landing), VFR aircraft, same procedures with the standard NVFR 3nm circling area.
