General Information on JAA Medical Requirements.

There are two standards of JAA medical certificate:

JAR Class 1 for a professional flying licence
JAR Class 2 for a private flying licence

The medical requirements for an initial JAA medical certificate, the requirements for revalidation and renewal, how a JAA certificate may be gained or maintained after recovery from illness, and how to obtain a UK JAR licence if a non-UK medical certificate is held can be found on the CAA web site here

The Joint Aviation Requirements (JAR) are a series of regulations covering the whole of aviation that have been, or are being, implemented by the European states of the Joint Aviation Authorities (JAA). These replace national regulations so that a harmonised set of standards are applied by all the states. The aim is to allow a seamless interchange of aircraft, operations, training and licensing throughout the JAA states and thus the free movement of aviation personnel among them. A new system of European aviation regulation (EASA – the European Aviation Safety Agency) was introduced in September 2003, and will gradually supersede the JAR. However, medical regulation by EASA is not expected until 2008 at the earliest.
