"There is no strong link between the office-based examination of CVD and real world realities. Under the proposed GD, the assessment of interferes with or likely to interfere with is ascertained from office-based assessments only. This assessment cannot be made from office-based tests only and can only be determined by an in-flight practical test. While both aviation medicine and flight operations specialists will need to be involved in the development of protocols for in-flight testing, only a flight examiner or flight instructor will be in a position to assess the ability of a pilot with a CVD condition to operate an aircraft safely. Thus the effect that a CVD condition will have on the ability of a pilot to safely exercise the privileges of a licence is a flight operations issue, not a medical issue."
