Appendix XII — Categories of flight tests and associated flight test crew qualifications Regulation (EU) 2015/1039 Appendix XII Categories of flight test and associated flight test crew qualifications A.      General This Appendix establishes the qualifications necessary for flight crew involved in the conduct of flight tests for aircraft certified or to be certified in accordance with CS‑23 for aircraft with a maximum take‑off mass (MTOM) of or above 2 000 kg, CS‑25, CS‑27, CS‑29 or equivalent airworthiness codes. B.      Definitions 1.       "Flight test engineer" means any engineer involved in flight test operations either on the ground or in flight. 2.       "Lead flight test engineer" means a flight test engineer assigned for duties in an aircraft for the purpose of conducting flight tests or assisting the pilot in the operation of the aircraft and its systems during flight test activities. 3.       "Flight tests" mean: 3.1.    flights for the development phase of a new design (aircraft, propulsion systems, parts and appliances); 3.2.    flights to demonstrate compliance to certification basis or conformity to type design; 3.3.    flights intended to experiment new design concepts, requiring unconventional manoeuvres or profiles for which it could be possible to exit the already approved envelope of the aircraft; 3.4.    flight test training flights. C.      Categories of flight tests 1.       General The descriptions below address the flights performed by design and production organisations under [Annex I](#_DxCrossRefBm1649096856) (Part 21). 2.       Scope If more than one aircraft is involved in a test, each individual aircraft flight shall be assessed under this Appendix to determine if it is a flight test and when appropriate, its category. The flights referred to in point (6)(B)(3) are the only flights that belong to the scope of this Appendix. 3.       Categories of flight tests Flights tests include the following four categories: 3.1.    Category One (1) (a)     Initial flight(s) of a new type of aircraft or of an aircraft of which flight or handling characteristics may have been significantly modified; (b)     Flights during which it can be envisaged to potentially encounter flight characteristics significantly different from those already known; (c)      Flights to investigate novel or unusual aircraft design features or techniques; (d)     Flights to determine or expand the flight envelope; (e)     Flights to determine the regulatory performances, flight characteristics and handling qualities when flight envelope limits are approached; (f)      Flight test training for Category 1 flight tests. 3.2.    Category Two (2) (a)     Flights not classified as Category 1 on an aircraft whose type is not yet certified; (b)     Flights not classified Category 1 on an aircraft of an already certified type, after embodiment of a not yet approved modification and which: (i)      require an assessment of the general behaviour of the aircraft; or (ii)      require an assessment of basic crew procedures, when a new or modified system is operating or is needed; or (iii)     are required to intentionally fly outside of the limitations of the currently approved operational envelope, but within the investigated flight envelope. (c)      Flight test training for Category 2 flight tests. 3.3.    Category Three (3) Flights performed for the issuance of statement of conformity for a new-built aircraft which do not require flying outside of the limitations of the type certificate or the aircraft flight manual. 3.4.    Category Four (4) Flights not classified as Category 1 or 2 on an aircraft of an already certified type, in case of an embodiment of a not yet approved design change. D.      Competence and experience of pilots and lead flight test engineers 1.       General Pilots and lead flight test engineers shall have the competences and experience specified in the following table. <table border="1" cellpadding="0" cellspacing="0" width="608"> <thead> <tr> <td valign="top" width="271"> <p></p> </td> <td colspan="4" valign="top" width="337"> <p><b>Categories of flight tests</b></p> </td> </tr> <tr> <td valign="top" width="271"> <p><b>Aircraft</b></p> </td> <td valign="top" width="84"> <p><b>1</b></p> </td> <td valign="top" width="84"> <p><b>2</b></p> </td> <td valign="top" width="84"> <p><b>3</b></p> </td> <td valign="top" width="84"> <p><b>4</b></p> </td> </tr> </thead> <tr> <td valign="top" width="271"> <p>CS‑23 commuter or aircraft having a design diving speed (Md) above 0.6 or a maximum ceiling above 7 260 m (25 000 ft), CS‑25, CS‑27, CS‑29 or equivalent airworthiness codes</p> </td> <td valign="top" width="84"> <p>Competence level 1</p> </td> <td valign="top" width="84"> <p>Competence level 2</p> </td> <td valign="top" width="84"> <p>Competence level 3</p> </td> <td valign="top" width="84"> <p>Competence level 4</p> </td> </tr> <tr> <td valign="top" width="271"> <p>Other CS‑23 with an MTOM of or above 2 000 kg </p> </td> <td valign="top" width="84"> <p>Competence level 2</p> </td> <td valign="top" width="84"> <p>Competence level 2</p> </td> <td valign="top" width="84"> <p>Competence level 3</p> </td> <td valign="top" width="84"> <p>Competence level 4</p> </td> </tr> </table> 1.1     Competence level 1: 1.1.1  Pilots shall comply with the requirements of Annex I (Part‑FCL) to Commission Regulation (EU) No 1178/2011 of 3 November 2011[[69]](#_ftn69). 1.1.2  Lead flight test engineer shall have: (a)      satisfactorily completed a Competence level 1 training course; and (b)     a minimum of 100 hours of flight experience, including flight test training. 1.2     Competence level 2: 1.2.1  Pilots shall comply with the requirements of Annex I (Part‑FCL) to Commission Regulation (EU) No 1178/2011 of 3 November 2011. 1.2.2  The lead flight test engineer shall have: (a)      satisfactorily completed a Competence level 1 or level 2 training course; and (b)     a minimum of 50 hours of flight experience, including flight test training.
