Overwing exits are installed on a number of smaller transport aircraft. With a traditional overwing exit, once released, the hatch is not attached to the fuselage and will fall into the cabin. To operate, the hatch has to be brought inwards, manoeuvred and placed in a location where it does not obstruct egress. Accidents and experimental studies have shown that the hatch is not always disposed of into an appropriate location. Evacuation trials from a smaller transport aircraft cabin were conducted. The placement of the exit hatch was manipulated. The results indicated that hatch placement had a significant effect on passenger evacuation rates from a smaller transport aircraft, with the internal placement tested resulting in slower evacuation rates. The study has highlighted the importance of operators disposing of the hatch into a location whereby it does not impede egress. One way to ensure this would be the installation of an automatically disposed hatch. Statement of Relevance: It is important that all occupants can evacuate an aircraft rapidly if required. The influence of overwing hatch placement on evacuation from smaller transport aircraft was addressed Evacuation trials concluded that an inappropriately placed hatch can negatively influence evacuation rates. Improvements to exit design and passenger education were suggested.
许多小型运输飞机上都安装了超翼出口。传统的超翼出口一旦释放，舱门就不会与机身相连，而是会掉入机舱内。为了操作，舱门必须向内移动、操纵并放置在不阻碍出口的位置。事故和实验研究表明，舱门并非总是被放置在适当的位置。从较小的运输飞机机舱进行了撤离试验。操纵出口舱门的位置。结果表明，舱门的位置对较小的运输飞机上乘客的撤离速度有显著影响，内部位置测试导致撤离速度较慢。该研究强调了操作人员将舱门放置在不妨碍出口的位置的重要性。确保这一点的一种方法是安装自动处置的舱门。相关性声明：如果需要，所有乘客都能迅速从飞机上撤离是很重要的。超翼舱门位置对小型运输飞机撤离的影响得到了研究。撤离试验得出结论，放置不当的舱门可能会对撤离速度产生负面影响。建议改进出口设计和乘客教育。
