Determination of Handling Qualities and Display Requirements for Helicopter Instrument Flight During Decelerating Approaches to Slow Speeds (Determination des Exigences en Matiere de Qualites de Manoeuvarabilite et d'Affichage pour le Vol aux Instruments des Helicopteres Pendant les Approches en Deceleration a de Faibles Vitesses).
Abstract
This paper discusses the most recent phase of a series of experiments performed jointly by the National Aeronautical Establishment and the United States Federal Aviation Administration. The experiment was aimed at determining the helicopter instrument flight handling qualities requirements when performing steep approaches to low decision heights to a landing area colocated with a Microwave Landing System. A total of 118 approaches were evaluated by three helicopter certification test pilots and one operational/training helicopter pilot. Results indicate that with simple rate damping augmentation in pitch, roll and yaw, and flight director guidance, a Bell 205A-1 exhibited borderline Level 1 (certifiable) handling qualities when performing decelerating approaches to 20 knots to decision heights representative of Category IIIA weather limits. Keywords: Helicopter handling; Instrument flight; (Canada).
