What does Instrument approach procedures (IAP) describe?

• A. A series of predetermined maneuvers for the orderly transfer of an aircraft under IFR from the beginning of the initial approach to landing.
• B. A set of air traffic control clearances issued for IFR flights.
• C. A weather briefing required before IFR flight.
• D. A navigation aid used only in VFR flight.

Answer: (A)

Instrument approach procedures describe a published sequence of predetermined maneuvers and altitudes that guide an aircraft under IFR from the initial approach to the runway, enabling a controlled descent and alignment for landing. They define the path in segments—initial, intermediate, and final approach—along with any required course guidance, altitude restrictions, and the missed-approach procedure if the landing cannot be completed. These procedures are designed to ensure obstacle clearance and safe navigation using navigation aids or GPS, and they are specifically for IFR operations.
