Height-Velocity Diagram

HELICOPTER AERODYNAMICS WORKBOOK

CHAPTER 4

Skilled test pilots who try to make their reactions simulate those of the average reaction time

of a pilot establish H-V diagrams. This is done by specifying a definite delay time following the

engine failure before initiating control input. The military assumes their pilots may be distracted

during an engine failure due to focused attention to assigned missions, allowing a two-second

delay before response during any flight condition.
