powered cruise descent avia.

[Alex777]

Пожалуйста, помогите перевести.

For a powered cruise descent, the mixture is gradually enriched in preparation for landing.

powered cruise descent - снижение на крейсерской мощности?

и еще
If a go-round is necessary, the carburettor heat must be set to cold in order to achieve full power. The mixture is usually set fully rich as part of the pre-landing checks unless the landing is taking place at a very high-altitude airfield.

go-round - обход?
high-altitude field - высокогорная посадочная площадка?

1) наверное да...
2) go around = "повторный заход" или "уход на второй круг"

последнее - скорее "горный аэродром" http://www.icao.int/icao/en/assembl/a35/wp/wp108_ru.pdf
