Medical required for SIM checks
 

Is a valid Medical required for Simulator Training or Checks? I.e., does the Instructor/Examiner need a valid Medical and does the Applicant/Trainee need a valid Medical?

Depends...

Your company may require a valid medical.
The examiner may want to see a valid medical.
A medical certificate is required to act as PIC, under EASA & FAA.
EASA (or at least UK CAA, acting under) requires a valid medical for any “licensing action” (endorsing/adding a rating; change of name/address/nationality; or correcting the Instructor privileges that they mistakenly omitted on earlier issue)
FAA used to require a Class 3 for ATP issue, but not the Sim check-ride.
EASA also does not require a valid medical for a Class Rating in an aeroplane (not acting as PIC).

Hope this helps.

Well - the examiner is working under the NAAs authority which is working under EASA rules. So I believe that the examiner may not want to see anything that is not required under EASA rules. That holds true for a company as well imho.
Do you have a reference where the EASA requirements are laid down?
