Approach Light Secrets

As much as we drill instrument students on the 10 items from FAR 91.175 (c) you could see to go below DA/MDA, in the real world if we see anything that might be part of the runway, we land on it. Its nearly certain that youll first see the ALS, allowing you to descend to 100 feet AGL and search for something resembling a runway.

Key Takeaways:

  • Approach Lighting Systems (ALS) are essential for safely transitioning from instrument to visual flight, providing critical orientation, visual guidance, and a means to measure flight visibility.
  • Pilots must understand the specific components and functions of various ALS configurations, such as the ALSF-2 with its sequenced flashing lights and roll bar, and other variations like ALSF-1 or ODALS.
  • Briefing the expected ALS is crucial for accurately assessing flight visibility based on the lights seen, making informed decisions at Decision Altitude/Minimum Descent Altitude, and utilizing available controls to optimize light intensity.
