Which NOTAM type alerts pilots to interim IFR flight procedures?

• A. NOTAM D
• B. Pointer NOTAM
• C. FDC NOTAM
• D. Military NOTAM

Answer: (C)

FDC NOTAMs (Flight Data Center notices) are specifically designed to alert pilots to changes in published flight procedures, including changes to instrument flight rules (IFR) procedures. They provide critical information regarding the alteration of procedures that must be adhered to by pilots.

In contrast, other NOTAM types serve different purposes. NOTAM D notifies pilots about information that is essential for the safe movement of aircraft, which may include things like airport conditions or navigational facility outages, but not necessarily interim procedures. Pointer NOTAMs are used to direct users to another NOTAM, often helping to point out relevant information but not providing procedural changes themselves. Military NOTAMs pertain specifically to military operations and do not address interim IFR procedures applicable to civilian operations.

Thus, the correct choice indicating which NOTAM type does not alert pilots to interim IFR flight procedures is indeed FDC NOTAMs, as they focus on changes rather than interim procedural alerts.
