## Supporting information

Additional information

  The UK Civil Aviation Authority (CAA) guidelines state:

  "In order to prevent the very slight risk of post-donation faintness or syncope, donating blood or plasma should be avoided during the 24 hours before duty for holders of Class 1 and 2 medical certificates, and during the 12 hours before duty for holders of Class 3 medical certificates."

  There is no CAA guidance for crew that are not required to hold these types of medical certification. Donors to whom this applies, including cabin crew and some private pilots, should be advised not to donate if they are on duty within the next 24 hours in line with commercial pilots and other flight crew.

  The Ministry of Defence (MOD) guidelines state:

  "Aircrew and Supernumerary Crew should not fly until 36 hours have elapsed after donating blood."

  and

  "Military and MOD Contracted Civilian Controllers should not control until 12 hours have elapsed after donating blood."

Reason for change:
  Updated Civil Aviation Authority advice for holders of Class 3 medical certificates has been added.
