Final answer:
The duplication of NOTAMs should be avoided to prevent confusion and ensure accurate dissemination of information in aviation.
Step-by-step explanation:
The duplication of NOTAMs, or Notices to Airmen, should be avoided to prevent confusion and ensure the accurate dissemination of information in the aviation industry. NOTAMs are important notices that provide pilots with critical information about potential hazards and changes in flight conditions. Duplicate or repetitive NOTAMs can clutter communication channels and make it difficult for pilots to identify the most relevant and up-to-date information. It is therefore important for aviation authorities and operators to coordinate and consolidate their NOTAMs to minimize duplication.
