GM1 ATM/ANS.OR.A.085(b)(4) Aeronautical data quality management ED Decision 2020/008/R RESOLUTION (a) Stating that resolution needs to be commensurate with the actual accuracy means that digital data needs to have sufficient resolution to maintain accuracy. Typically, if an accuracy of .1 unit is needed, then a resolution of 0.01 or .001 units would enable a data chain to preserve the accuracy without issue. A finer resolution could be misleading as one could assume that it supports a finer accuracy. This factor range of 10 to 100 between accuracy and resolution is applicable regardless of the units of measurements used. (b) The resolution should be enough to capture the accuracy of the data.
