Measurements have been made of cockpit temperatures in a Buccaneer aircraft exposed to high air temperatures and radiation loads. With the canopy open 8 cm, and with the wind direction unfavourable for convective cooling, air temperatures inside the cockpit exceeded those outside by approximately 20 degrees C. This reduced to 10 degrees C with a favourable wind direction. An assessment of the likely heating effect of cockpit avionic equipment indicated that the addition of 1 kW and 2 kW of heat would raise cockpit temperatures by 20 degrees C and 30 degrees C respectively. Prediction of the combined effect of solar and avionic heat suggests that, in hot weather conditions, cockpit temperatures will be considerably in excess of the upper limit for effective physiological temperature regulation. Therefore, if aircrews are to be required to remain on ground standby within their aircraft under such conditions, maximum use must be made of convective cooling of the cockpit by the prevailing wind, and of sun shades to eliminate the greenhouse effect completely.
对一架“掠夺者”飞机驾驶舱在高气温和辐射负荷下的温度进行了测量。当座舱盖打开8厘米，且风向不利于对流冷却时，驾驶舱内的气温比外部高出约20摄氏度。当风向有利时，这一温差降至10摄氏度。对驾驶舱航空电子设备可能产生的加热效应的评估表明，增加1千瓦和2千瓦的热量将分别使驾驶舱温度升高20摄氏度和30摄氏度。对太阳热和航空电子设备热量综合效应的预测表明，在炎热天气条件下，驾驶舱温度将大大超过有效生理温度调节的上限。因此，如果要求机组人员在这种条件下在飞机内处于地面待命状态，必须最大限度地利用盛行风对驾驶舱进行对流冷却，并使用遮阳罩完全消除温室效应。
