I describe a general method that has been used for the in-flight cross-calibration of the CDS spectrometers. This method relies on accurate atomic data and uses the Sun as a "calibration' source. It was successfully applied in the past to calibrate other EUV spectrometers. The results show significant differences from the laboratory calibration, good agreement with the calibrations based on two rocket-flights flown in 1997 and excellent stability of the CDS instrument during the same year. It is suggested that this method be used to monitor the in-flight calibration of future EUV spectrometers.
