Points for Pilots

  Magenta area with MVFR airport West Texas loves low ceilings in the morning, an amazing fact when you consider that this is desert country. A notable exception is the Pecos airport, which evidently has a secret contract with the weather gods for unlimited ceiling and visibility year round. We plan accordingly. When we go west from Dallas, we carefully monitor the ceiling of our preferred refueling stop, the uncontrolled airport Andrews in the Midland/Odessa area. Andrews almost always has ceilings of less than 500 ft in the morning. If the ceiling lifts to at least 1,000 ft by the time we get there, we land and refuel. If that fails, we detour to Pecos, which invariably is VFR. Andrews is surrounded by a magenta boundary.

We could simply f
