![]() Examination of the wreckage did not reveal anyĮvidence of preimpact mechanical malfunctions. Radar plots revealed that the airplane flew into an area of extreme intensity precipitation and thenĮntered a rapid descent and impacted the ocean. Review of the airplane's GPS track overlaid on weather The instructions, a review of radar and GPS data for the flight revealed that he continued on course.Ībout 3 minutes later, the pilot reported he was reversing direction, and no furtherĬommunications were received from the pilot. ![]() Should turn left and fly offshore 3 miles to avoid the thunderstorm. The controller further advised that the pilot The airplane's 12-o'clock position and 4 miles ahead. The controller approved the request but advised of heavy precipitation (a thunderstorm) at The pilot requested from air traffic control to fly below 500 ft above ground level along the ocean The pilot did not receive a weather briefing before beginning the cross-country flight. And with that, you have the developing stage of a thunderstorm. This creates a towering cumulus cloud, or TCU. As it rises, that temperature gap grows, and the air continues to accelerate upward, forming a strong updraft. (It takes energy to turn water into a gas, and that energy releases as heat as the gas condenses back into water.) Now that moisture is condensing out of the lifted air, it's much warmer than the surrounding air. It's the lowest altitude that condensation occurs because of convection from surface heating.Īs moisture condenses out of the air, it releases energy. This altitude is the convective condensation level. ![]() Once it hits the dew point, moisture starts to condense out of the air, forming clouds. ![]() The temperature keeps dropping and approaching the air's dew point. You probably know that thunderstorms require three ingredients to form: moisture, instability and a lifting action.Īs you lift air from the surface, it cools. But First.A Quick Refresher On How Thunderstorms Form What looks like a harmless cumulus cloud can quickly become a thunderstorm in the right conditions. ![]()
