A medical certificate can be revalidated before it expires or renewed after it has expired.

Revalidation and renewal examinations should take less time than those required for initial issue and they may not require all the additional tests. This depends on when the last test was carried out, the type of certificate held and your age at examination.


You can revalidate your medical certificate by taking a revalidation examination at an Aeromedical Centre (AeMC) or by appointment with an Aeromedical Examiner (AME).

You can undertake your revalidation examination up to 45 days before your certificate’s expiry date. There will be no loss of validity as the validity period will be calculated from your current certificate's expiry date.


If you do not revalidate your certificate in the 45 days leading up to its expiry date, you will need to have it renewed by undertaking a renewal examination at an Aeromedical Centre (AeMC) or by appointment with an Aeromedical Examiner (AME), subject to the following conditions:

  • If your certificate expired more than 2 years before your application to renew it, the examiner will need to assess your aero-medical records before carrying out the renewal examination
  • If your certificate expired more than 5 years before, then you will have to follow the same process as for initial issue.

The expiry date is calculated from the date of your renewal examination.
