Good to know

One-Off notification flights: A regulatory provision (TCO.305 Non-scheduled flights – one off notification) is available to allow certain flights to be operated without a TCO authorisation. This provision is solely applicable to the following cases:

  • air ambulance flights, and
  • non-scheduled flights “to overcome an unforeseen, immediate and urgent operational need”. 

Such flights should be performed in the public interest and where the urgency of the mission justifies by-passing the regular TCO assessment process, e.g. humanitarian missions or disaster relief operations.


Additional information may be requested during office hours on: +49 – (0)221 - 89990 6100 or tco [at] (tco[at]easa[dot]europa[dot]eu).
