Multiple Choice

Which statement about NOTAM length is true?

A NOTAM should not exceed 1,500 characters or 20 lines. This limit keeps messages concise and ensures they can be processed and read quickly by pilots and air traffic services. If more detail is needed, the proper approach is to issue additional NOTAMs or spread the information across multiple NOTAMs rather than making one message longer than the allowed size. The 1,500-character cap aligns with how information is entered and displayed in systems, while the 20-line cap provides a practical bound for older display formats.
