MIRL is used for which type of approaches?

• A. Non-precision approaches
• B. Precision approaches
• C. Visual approaches
• D. All types of approaches

Answer: (A)

MIRL stands for Medium-Intensity Runway Lighting. It is tied to instrument procedures that provide lateral guidance but not vertical guidance—that is, non-precision approaches. On these approaches, pilots rely on lateral navigation cues to align with the runway, and MIRL helps by giving a moderate level of lighting to clearly identify the runway environment, threshold, and final path for safe descent and landing. For precision approaches, which include vertical guidance (like ILS), higher or different lighting and guidance systems are used, and MIRL isn’t the defining lighting for those approaches. Visual approaches rely mainly on outside visibility rather than instrument lighting cues. So MIRL is best associated with non-precision approaches.
