But please note that “suspended” is not the same as expired/not present.
Examiners have a duty of care, as do employers. Is this a special case of “fit for simulator” but not “fit to fly”?
With respect to medication, is the underlying condition enough to consider you unfit (eg pain), or is this a more general medical condition that requires long-term medication (and a provisional suspension to assure no adverse effects)?
The Examiner is expected to ensure that you are fit to complete the LPC, and not claim afterwards that failure was due to lack of medical fitness.
From the Flight Examiner Handbook:
2.3.3. If the examiner is satisfied that all relevant documentation is in order he may proceed with the check/test; however, if the inspection of the documentation raises any concerns as to the fitness or qualification of the individual to take the test or to exercise the privileges which a pass would confer, the examiner should refer the matter to the CAA for confirmation that he may proceed with the test.
In short, there are too many variables: you may be 100% OK, or it may be considerably unwise (think subtle incapacitation).
Good luck.
