(3)Indicated airspeed;
(45)DME 1 and 2 distances;
(76)APU bleed valve position (when an information source is installed);
(b) For all turbine-engine powered transport category airplanes manufactured on or before October 11, 1991, by August 20, 2001 -
(1) For airplanes not equipped as of July 16, 1996, with a flight data acquisition unit (FDAU), the parameters listed in paragraphs (a)(1) through (a)(18) of this section must be recorded within the ranges and accuracies specified in Appendix D of this part, and -
(c) For all turbine-engine-powered transport category airplanes manufactured on or before October 11, 1991 -

A correlation must be established between the values recorded by the flight data recorder and the corresponding values being measured. The correlation must contain a sufficient number of correlation points to accurately establish the conversion from the recorded values to engineering units or discrete state over the full operating range of the parameter. Except for airplanes having separate altitude and airspeed sensors that are an integral part of the flight data recorder system, a single correlation may be established for any group of airplanes -
(l) The following airplanes that were manufactured before August 18, 1997 need not comply with this section, but must continue to comply with applicable paragraphs of § 125.225 of this chapter, as appropriate:
