Basis for Reprocessing
C, a 2% or 3% standard error is tolerable relative to the expected uncertainty in the measurement. However, failure to correct for the 50% reduction in pressure present at Mach number above 0.8 would produce an error of around 10
C, which would be quite significant. This illustrates the importance of making these corrections to data from projects flown before the pressure measurements in the housing were available.
