However, modern aircraft are now built to design standards that automatically include these safety features during manufacturing, making the old rule redundant.\n\n**Who is affected**\nAircraft operators, maintenance engineers, and aviation businesses that previously had to comply with this specific calibration requirement.\n\n**Practical impact**\nOperators no longer need to follow this directive or keep records showing compliance with it. The safety outcomes are now guaranteed by the aircraft's type certification standards instead of this separate operational rule."}},"importantCases":[],"_links":{"self":"/api/acts/ad-general-46-placarding-of-fuel-quantity-indicators-modification-cancelled","history":"/api/acts/ad-general-46-placarding-of-fuel-quantity-indicators-modification-cancelled/history","analysis":"/api/acts/ad-general-46-placarding-of-fuel-quantity-indicators-modification-cancelled/analysis","conflicts":"/api/acts/ad-general-46-placarding-of-fuel-quantity-indicators-modification-cancelled/conflicts","importantCases":"/api/acts/ad-general-46-placarding-of-fuel-quantity-indicators-modification-cancelled/important-cases","documents":"/api/acts/ad-general-46-placarding-of-fuel-quantity-indicators-modification-cancelled/documents"}}
