It is used to store pilot logbook entries, flight times, aircraft details, routes, and related operational records for personal and professional aviation record keeping. The format is generally considered low risk; as with other legacy desktop data files, it should still be opened from trusted sources because malformed files may cause application errors.","mime":[],"risk_level":"Safe","signatures":[{"hex":"C8 00 79 00","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":[],"usage":{"python":"def is_lbk(file_path: str) -> bool:\n    \"\"\"Check if file is a valid LBK by magic bytes.\"\"\"\n    signature = bytes([0xC8, 0x00, 0x79, 0x00])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isLBK(buffer: Buffer): boolean {\n  const signature = Buffer.from([0xC8, 0x00, 0x79, 0x00]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsLBK(data []byte) bool {\n    signature := []byte{0xC8, 0x00, 0x79, 0x00}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"}}}
