For planning a mission in the United States, which reference provides supplementary airfield information?

• A. AP/1
• B. IFR Supplement
• C. A/FD
• D. AIM

Answer: (A)

This question is about where to find extra airfield details used for planning a flight in the United States. AP/1 is the publication that contains supplementary airfield information—such as field conditions, services available, lighting notes, and any special considerations that affect planning. The IFR Supplement covers instrument procedures and approaches, not extra airfield notes. The A/FD lists the core airport and facility data, but supplementary notes are provided separately in AP/1. The AIM offers general aviation information and guidance, not specific airfield details. So AP/1 is the best source for supplementary airfield information.
