 | The definition of flight test will vary as widely as the activity of those who are pursuing the subject. Perhaps the only consensus is that the vehicle be in free atmosphere as opposed to a wind tunnel or an enclosure. Scale models, unpiloted vehicles, tethered, or constrained vehicles are flight tested. The type of power or even the absence of power is not a decisive factor. Flight test may involve ... |

|
 | During weapons fire control tests being conducted by Frankford Arsenal, Philadelphia, Pennsylvania, it was necessary to determine the optimum location for an Elliott low airspeed system mounted on an AH-1G helicopter to improve the accuracy of the actual aircraft airspeed signal to the fire control computer. The airspeed system was provided by Frankford Arsenal, and the necessary mounting hardware was constructed by the United States Army Aviation Engineering Flight Activity, ... |

|
| Tests were conducted to evaluate the airspeed and direction-sensing capability of the Elliott low airspeed sensing and indicating equipment system (LASSIE II). The system included the basic dual-axis probe, an electronic package including a linearization circuit, a pressure altitude sensor, and a vertical speed computer. The probe is a pivoted vane designed to align with resultant flow and incorporates equipment which measures angles in all directions from the vertical. The ... |

|
| A limited investigation was conducted to evaluate the effects of maneuvering flight during autorotation and the flight characteristics during power recovery from autorotation. The testing consisted of 6.5 flight hours and was conducted from 11 December 1967 through 24 January 1968. The tests indicated that the existing method of presenting autorotation rate of descent information in the operator's manual is not representative of the operational requirement. A maximum glide technique ... |

|
| The Army Preliminary Evaluation of the UH-1C/XM-30 weapon system was conducted by the U. S. Army Aviation Test Activity at Edwards Air Force Base and Fort Irwin, California. The degradation in level flight performance attributed to the weapon installation was defined and no objectionable flying qualities were encountered during firing or non-firing tests. The armed mission capability of the helicopter was degraded by high levels of stress, vibration, blast, and ... |

|
| An engineering flight research evaluation of the XV-5A aircraft was conducted to obtain performance criteria applicable to future Army developmental aircraft using the lift-fan concept. The testing consisted of 18.1 productive flight hours and was conducted from 22 July through 15 November 1965. The performance capability was sufficient to allow an evaluation of the over-all concept/installation. The hovering power required was less than that necessary at conversion. With the proper ... |

|
| An engineering flight research evaluation was conducted to investigate the flying qualities and stability and control characteristics of the research model XV-5A lift-fan vertical and short takeoff and landing (V/ STOL) aircraft. Testing consisted of 24.2 productive flight hours and was conducted from 28 January through 30 June 1965. The flying qualities of the XV- 5A observed during this evaluation were suitable for accomplishment of its primary mission as a ... |
