What is your decision? = Report your decision. Доложите ваше решение.
We’d like to divert to our alternate. Мы хотим уйти на наш запасной.
Caution: windshear reported at 6000 feet 2 miles final. Осторожно: докладывали о сдвиге ветра на высоте 6000 футов в 2 милях на предпосадочной прямой.
Windshear warning: strong low level windshear observed in the vicinity of Beijing airport at 1400 hours. Предупреждение о сдвиге ветра: сильный сдвиг ветра на низкой высоте наблюдался в районе аэропорта Пекин в 1400.
Height of windshear layer 1500m. Слой высоты сдвига ветра 1500м.
Windshear alert: centerfield wind 210° at 14 knots, east boundary wind 140° at 22 knots. Предупреждение о сдвиге ветра: ветер в центре летного поля 210° 14 узлов, восточная граница 140° 22 узла.
Encountered windshear on final gained 20 knots between 600 and 400 feet followed by a loss of 30 knots between 400 feet and the surface. Столкнулся со сдвигом ветра на предпосадочной прямой, что привело к увеличению скорости на 20 узлов между 600 и 400 футами, за которым последовала потеря скорости на 30 узлов между 400 футами и поверхностью.
