Information for health professionals, air crew and passengers on the health aspects of air travel.

The CAA website provides a wide range of information for passengers including aviation health. The Aviation Health Unit's frequently asked questions offer information and guidance on aviation health, such as whether you are fit to fly and what to do if you need to take medication or medical equipment through airport security. 

There is also a section providing guidance for health professionals on assessing the fitness of their patient for travel by air.
