爬升率 Rate of climb

(重定向自Sink rate)
F-15的爬升
El Boeing 737 Enter Air ascendiendo desde el aeropuerto de Cracovia

在中,爬升率Rate of climb,RoC)是指飞机升高海拔的速度。大部份国际民航组织会员国以英尺每分为爬升率的单位,缩写为ft/min。其他国家则用公尺每秒为爬升率的单位,缩写为m/s。飞机上会用垂直速度指示器(VSI)或瞬时垂直速度指示器(IVSI)显示其爬升率。

飞机降低海拔的速度称为下降率,对应爬升率为负值时的情形。

有人驾驶的飞机其最初爬升率的最高记录是由米格-29战斗机创下的330 m/s(65,000 ft/min)。米格-29战斗机从海平面上升到海拔6000米的平均爬升率为109m/s。

Rate of climb 爬升率

(重定向自Sink rate)

Boeing 737 Enter Air, climbing with normal angle of attack for civil airplanes, to give optimal rate of climb

In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed – the rate of altitude change with respect to time. In most ICAO member countries (even in otherwise metric countries), this is usually expressed in feet per minute (ft/min). Elsewhere, it is commonly expressed in metre per second (m/s). The rate of climb in an aircraft is indicated with a vertical speed indicator (VSI) or instantaneous vertical speed indicator (IVSI).
