Final answer:
NOTAMs should not be used to advertise data already available in other media sources
Step-by-step explanation:
NOTAMs (Notices to Airmen) are used to provide pilots and aviation personnel with important information regarding the state of the National Airspace System (NAS). However, NOTAMs should not be used to advertise data that is already available or disseminated correctly through other media sources such as FLIPS (Flight Information Publications) or the FAA Notice to Airmen Publication (NTAP).
