Airworthiness and Flight Characteristics (A&FC) Test of YAH-64 Advanced Attack Helicopter, Prototype Qualification Test-Government (PQT-G). Part 3 and Production Validation Test-Government (PVT-G) for Handbook Verification
Abstract
The Airworthiness and Flight Characteristics Test of the YAH-64 helicopter was conducted. Seventy flights and 70.4 productive hours were flown. Performance testing assessed the probability of meeting the production contract requirements and consisted of an evaluation of hover, takeoff, level flight, forward flight climb and autorotational descent performance. Handling qualities testing determined compliance with selected research and development contract requirements and included standard stability and control tests, an evaluation of slope landing characteristics and instrument flight capability. Additional tests included evaluation of an uprated engine and an external noise survey. The YAH- 64 now meets the performance requirements of the system specification for the production program; the vertical climb and maximum level flight cruise speeds. Slope landing characteristics were satisfactory up to 9 degree lateral slopes and 10 degree longitudinal slopes.
