There are a lot of things covered by these policies so it's sometimes hard to find exactly what you are looking for. The Trackday Organiser (TDO) may want to see the word "Repatriation" or references to "bringing you home". to ensure you can get home in the event of an incident on track, in addition to cover for emergency medical treatment costs.
There are various references throughout the policy document to repatriation, but in particular if you look for the section called "If you need to be brought home" (Section B7 in the Silver Level policy and Section B8 in Gold Level).
