A multi-alternative PCRE pattern (with global/multiline flags) for parsing NFDC (National Flight Data Center) aviation data. It matches slash-delimited NFDC identifiers like 'NFDC/xx/xx/xx/xx-xx/nn-nn', '(Sec)' section headers followed by descriptive text, 'Channel Name :' entries with optional frequency values, and numbered records paired with date strings in n/n/n format. Useful for extracting facility codes, channel names, and dated entries from FAA/aviation data files.
