Instrument-flying trials have been conducted in a single-rotor helicopter to determine the adequacy of existing longitudinal flying-qualities requirements under instrument conditions. In addition, laterial directional characteristics were examined. The suitability, for helicopter use, of standard airplane insruments was also investigated.NACA TN No. 2721."June 1952."Includes bibliographical references.Instrument-flying trials have been conducted in a single-rotor helicopter to determine the adequacy of existing longitudinal flying-qualities requirements under instrument conditions.
