This report presents the results of an engineering flight evaluation conducted to determine the technical engineering flight characteristics of the prototype Model 209, S/N N209J, Huey Cobra weapons helicopter. This evaluation was conducted by the U. S. Army Aviation Test Activity (USAAVNTA), Edwards Air Force Base, California. Tests were conducted at Edwards Air Force Base, California. Twenty-nine flights were made for a total of 32 hours flying time during the period 13 November through 1 December 1965. The USAAVNTA was assigned responsibility for preparing the test plan, executing the test and preparing the test report. The results of these tests show that the Cobra design offered speed, maneuverability, good fields of vision from the cockpit, and other desirable armed aircraft characteristics not presently available from any helicopter in the U. S. Army inventory. The maximum (power limited) level flight airspeed at sea level with no external stores and the landing gear retracted was 162 knots true airspeed. Acceptable vibration levels and flight characteristics for a weapons platform were present during all test conditions which included the limit dive speed of 190 knots calibrated airspeed (KCAS).
