I trust that everyone is/will be notifying Flight Crew Standards if they intend to use an aircraft (rather than a FFS or OTD) for Class or Type Rating Skill Tests or FI pre-course proficiency checks on UK-issued EASA licence holders, in accordance with IN-2012/155.
An examiner conducting test/checks or assessments of competence, outside of an AOC operation, who intends to use an aircraft for the purposes of Part-FCL should advise Flight Crew Standards of their intent and why a simulator is not available against the criteria above.
