2 Aviation meteorology industry should in close collaboration with the General Directorate of Hydrometeorology pay more attention to the characteristics of the meteorological forecasts for Aviation industry, inform timely of thunderstorms, low pressure and climate changes in order to take precaution against windshears and vortex which cause violent downdraft and updraft.
3 Control towers at airports near the coast should have adequate meteorological equipment, and the controllers should improve their skills in controlling aircraft during approach.
4 Regarding Nha Trang Airport, if there appears a typhoon 250-400 km away, that typhoon should be watched and kept trace. If the typhoon is within a radius of 200 km or the airport is within the typhoon area, an alert should be initiated and the airport should be closed.
