Approach lighting systems are critical during low ceiling and low visibility conditions when you must decide whether to continue to land or execute a missed approach. If when reaching the minimum descent altitude or decision altitude on the approach and you have the approach lights in sight, you are permitted to descend to 100 feet above the touchdown zone elevation published for the runway.

Keep an eye on the weather as you approach the destination, using both ADS-B datalink weather, and by tuning in the local ATIS/AWOS on the radio. If it looks like the weather will be near the minimums for the approach, it is time to start thinking about what the best alternate airport will be based on the current weather. If it still looks like the planned alternate is the best option, go for it.

During your instrument training, you routinely fly instrument approach procedures to “minimums” under simulated conditions. The more likely scenario when flying under instrument flight rules (IFR) is the option to complete the flight under visual flight rules (VFR), flying a visual approach procedure, or flying an instrument procedure in which you acquire the runway visually well above the charted “minimums.”
