Evaluation of a Visual Departure Path Indicator.

摘要

The report describes a technique and presents the result of tests conducted to evaluate a visual departure path indicator for suitability to prevent spatial disorientation when an aircraft, under visual flight rules, departs from an airport over land or water where no horizon and few visual cues exist. The work involved determining if it is an appropriate type of system to use. After a satisfactory testing period the equipment was moved to an airport where spatial disorientation might be encountered and an in-service test was performed. The results are discussed.
