Nota adicional1
Prior to January 31, 1983, the height-velocity diagram was an operating limitation. It restricted operating helicopters in various utility applications. Now, the height-velocity diagram is performance information for Category B helicopters with 9 or fewer passenger seats but remains a limitation for Category A helicopters and Category B helicopters with 10 or more passenger seats. Height-velocity diagrams are based on a one-second delay in the pilot taking appropriate action.
Contexto
Helipads on buildings and oilrigs may require that the helicopter operate within the avoid areas of the height-velocity diagram during takeoffs and landings. Additionally, such operations may also limit the gross weight of the helicopter compared with operations from ground level.
