Key Takeaways:

Pilots are cautioned against violating instrument approach minimums, specifically regarding required flight visibility and the "normal maneuvers" rule, as many non-precision approaches have a Missed Approach Point (MAP) too close to the runway for a safe and legal landing.
Advisory Circular 90-108 permits the use of GPS in lieu of DME to identify position, such as the Missed Approach Point (MAP) on a VOR approach, but notes that moving maps are primarily for situational awareness, not precision navigation.

Going Below Minimums

Please thank Ken Maples for writing this much needed article that appeared in your May 2022 issue. Many of us pre-brief approaches from home, including highlighting the chart and adding annotations. From now on mine will include a visibility checkpoint. Interestingly, for my home field, S50, Auburn (Washington), the speed Category A minimum visibility is listed as 1¼ SM, which measured out from the threshold leaves about 0.8 NM to go before reaching the MAP.
