    Study Notes

    Runway Lighting Requirements

    • Adequate intensity is crucial for effectiveness in poor visibility conditions.
    • Lighting must also provide uniform illumination across the runway.

    Approach Lighting System Practices

    • Recommended practice includes gradual intensity changes to improve pilots' visual reference during descent.

    High-Intensity Lighting Systems

    • When high-intensity lighting is implemented, an automatic intensity reduction feature must be included.

    Barrettes Specifications

    • Minimum length for barrettes is specified, ensuring proper coverage and visibility.

    Central Lighting Specifications

    • The central 300 m of the center line contains at least three light sources.
    • A single light source may be used for the center line light position beyond 300 m from the threshold.

    Light Intensity and Positioning

    • Maximum light intensity value on the perimeter within the defined ellipse is established.
    • Minimum effective intensity for aerodrome beacon flashes must align with regulations.

    Aerodrome Beacon and Emergency Lighting

    • Aerodrome beacon should be located prominently for maximum visibility.
    • Recommendations for emergency lights include adequate backup systems where secondary power is unavailable.

    Centre Line Lighting Practices

    • Recommended length for center line lights in simple approach systems is defined.
    • Each center line light should be installed at specified lengths for uniformity.

    Crossbar Light Specifications

    • Crossbar lights in precision approach category I systems have specific location requirements.

    Centre Line Light Placement

    • True statements regarding the placement of center line lights ensure proper navigational aids.
    • Minimum required length for barrettes in precision approaches aligns with safety standards.

    Additional Lighting Recommendations

    • When barrettes are used for the center line, recommended additional lighting enhances visibility.

    Light Spacing Guidelines

    • Recommended spacing between lights in barrettes is detailed, ensuring no dark gaps in coverage.
    • Longitudinal spacing for the center line lights is established for uniform light emission.
    • Lateral spacing between the innermost lights of side rows must adhere to guidelines.

    Crossbar Distance and Specifications

    • Crossbar is provided at a specific distance from the threshold to aid approach visibility.
    • Additional crossbars for lights are required if the center line consists of certain configurations beyond 300 m from the threshold.

    Simple Approach Lighting Systems

    • Recommended spacing between lights in the crossbar of simple systems is indicated.
    • Maximum allowable gap between lights on each side of the crossbar maintains visual continuity.
    • Recommended length and distance of the crossbar from the threshold in simple systems are formulated for effective landing guidance.

    Identification Beacons

    • Recommended transmission speed for identification characters in Morse Code is outlined for effectiveness.

    Simple Approach Lighting System Coverage

    • Minimum distance for a row of lights in simple approach systems should extend beyond the runway threshold.
