导言本报告旨在鼓励更多努力，以提高飞行员在运输型飞机驾驶舱的能见度，最终目标是提高安全性。在编制本航空信息报告时，考虑了民航局进行的飞行员调查、制造商进行的研究，以及对当今运输飞机提供的驾驶舱能见度的审查。人们认识到，严格的规范是不可取的，可能会限制主动性的开发和利用。因此，本报告是一般性的，并作为指南提供。

INTRODUCTION This report is intended to encourage more effort to be directed toWard improving the pilot's visibility from the cockpit of transport type aircraft wih the ultimate objective of improving safety. In the preparation of this Aeronautical Information Report, consideration Was given to pilot surveys made by the Civil Aeronautics Administration, studies made by manufacturers, and a review of the cockpit visibility provided in present day transport aircraf`t. It is recognized that a rigid specification is undesirable and may restrict development and utilization of initiative. For this reason the report is in general terms and offered as a guide.
