1. a. The MALSF (Medium-Intensity Approach Lighting System with Sequenced Flashers) is only used on non-precision approaches.
2. c. The flashers stop at the decision bar for all ALSF and MALSF. They stop 400 feet before the decision bar on MALSR and SSALR systems.
3. b. The decision bar is the wide row of white lights 1000 feet before the
threshold. It helps make the transition from instrument to visual flight by providing a horizon line and orientation to the runway.
4. d. It’s 10 degrees and four miles. They should be visible from three to five miles away on sunny days.
5. c. Assuming no one else activates or adjusts the lighting intensity, the lights will stay on for 15 minutes. Non-standard lighting for runways without IAPs may not comply with this rule.
6. False. The exact combination of what’s controlled from the air and what isn’t varies from airport to airport.
