    weather for a particular flight, they should consider the following: ⦁ What are the current ceiling and visibility? In mountainous terrain, consider having higher minimums for ceiling and visibility, particularly if the terrain is unfamiliar. ⦁ Consider the possibility that the weather ... occur. ⦁ Consider the winds at the airports being used and the strength of the crosswind component. ⦁ If flying in mountainous terrain, consider whether there are strong winds aloft. Strong winds in mountainous terrain can cause severe turbulence and downdrafts…

    stronger the wind, the greater the downward pressure and turbulence become. Figure 12-16. Turbulence in mountainous regions. Due to the effect terrain ... wind in valleys or canyons, downdrafts can be severe. Before conducting a flight in or near mountainous terrain, it is helpful for a pilot unfamiliar with a mountainous area to get a checkout with a mountain qualified flight instructor…

    fatal accident in Colombia, a flight crew was unexpectedly cleared for an approach, lost situational awareness, and crashed into mountainous terrain. The accident summary cites failure of the flight crew to revert to basic radio navigation at the time when ... aircraft speed brakes when they became aware of the terrain ahead and after adding full thrust. This prevented the aircraft from climbing above the slope of the mountain ahead…
