If however, altitude is recorded at a minimum resolution of 25 feet, then these two parameters can be omitted. 3 Per cent of full range. 4 This column applies to aircraft manufactured after October 11, 1991. 5 For Pitch Control Position only, for all aircraft manufactured on or after April 6, 2012, the sampling interval (per second) is 8. Each input must be recorded at this rate. Alternately sampling inputs (interleaving) to meet this sampling interval is prohibited. [Doc.
