What must be maintained during IFR operations?

• A. ATC separation
• B. Visual separation
• C. Continuous airspeed
• D. Terrain clearance

Answer: (A)

During IFR operations, keeping aircraft separated from one another is the main safety requirement, and this is provided by ATC. Since flight is conducted by reference to instruments rather than visual cues, pilots rely on ATC to maintain horizontal and vertical spacing using standard separation minima, radar guidance, assigned altitudes, headings, and speeds. The pilot follows ATC instructions to preserve that separation throughout en route, approach, and in the terminal area. While terrain clearance and adhering to assigned speeds are important, they support the overarching need for ATC-provided separation to prevent conflicts.
