Which lighting is associated with runway 27R?

The correct answer identifies the full suite of lighting systems associated with runway 27R, which typically includes both operational and navigational aids crucial for pilots during approach and landing.

MALSR (Medium-intensity Approach Lighting System with Runway Alignment Indication Lights) provides essential visual guidance to pilots, especially in low visibility conditions, by helping them align with the runway. HIRL (High-Intensity Runway Lights) enhances the visibility of the runway itself, making it easier for pilots to identify the runway during both day and night operations.

Additionally, RAIL (Runway Alignment Indicator Lights) offers further visual cues that guide pilots as they approach the runway. The inclusion of PAPI (Precision Approach Path Indicator) is vital as it provides information about the aircraft's position in relation to the ideal glide slope, assisting in maintaining safe descent angles.

Sequenced flashing strobes further enhance the visibility of the runway environment, particularly in adverse conditions. This comprehensive combination of lighting aids not only promotes safety but also assists pilots in making accurate and confident landings.

Thus, the correct choice reflects the variety and complexity of the lighting systems in use, providing a clearer understanding of the operational requirements for runway 27R.
