The only exception is if the autopilot is approved for use at all speeds up to the aircraft's maximum safe speed (called *Vne* or \"never exceed speed\").\n\n**Why this amendment exists:** This update simply removes references to old documents that have been cancelled. It doesn't change the actual safety requirement, which has been in place since before 1971."}},"importantCases":[],"_links":{"self":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation","history":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation/history","analysis":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation/analysis","conflicts":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation/conflicts","importantCases":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation/important-cases","documents":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation/documents"}}
