                                      SINGLE- ENGINED TURBINE AEROPLANES AT NIGHT OR IN INSTRUMENT METEOROLOGICAL
                                      CONDITIONS (SET- IMC)
                                          (a)  When verifying compliance with the applicable requirements of Subpart L (SET-IMC) of
                                              Annex V (Part-SPA) to Regulation (EU) No 965/2012, the CAA should check that:
                                              (1) the aeroplane is eligible for SET-IMC operations;
                                              (2) the maintenance and operational procedures are adequate;
                                              (3) a training programme for the flight crew involved in these operations has been
                                                  established; and
                                              (4) the operator has adequately assessed the risks of the intended operations.
                                              In particular, the CAA should assess the operator’s safety performance, experience and
                                              flight crew training, as reflected in the data provided by the operator with its application, to
                                              ensure that the intended safety level is achieved.
                                              With regard to the operator’s specific SETIMC flight crew training, the CAA should ensure
                                              that it complies with the applicable requirements of Subpart FC (FLIGHT CREW) of
                                              Annex III (PartORO) and Subpart L (SETIMC) of Annex V (PartSPA) to Regulation (EU) No
                                              965/2012, and that it is appropriate to the operations envisaged.
                                              The CAA should assess the operator’s ability to achieve and maintain an acceptable level
                                              of power plant reliability by reviewing its enginetrendmonitoring programme and
                                              propulsion reliability programme, which are established in accordance with Annex I
                                              (PartM) to Regulation (EU) No 1321/2014.
                                          (b)  The CAA may impose temporary restrictions to the operations (e.g. limitation to specific
                                              routes) until the operator is able to demonstrate that it has the capability to operate safely
                                              in compliance with all the applicable requirements.
                                          (c)  When issuing the approval, the CAA should specify:
                                              (1) the particular engine-airframe combination;
                                              (2) the identification by registration of the individual aeroplanes designated for single-
                                                  engined turbine aeroplane operations at night and/or in IMC; and
                                              (3)  the authorised areas and/or routes of operation.
                                      VALIDATION OF OPERATIONAL CAPABILITY
                                      Observation by the CAA of a validation flight, simulating the proposed operation in the aeroplane,
                                      should be carried out before an approval is granted. This should include flight planning and preflight
                                      procedures, as well as a demonstration of the following simulated emergency procedures in
                                      simulated IMC/night:
                                          (a)  total failure of the propulsion system; and
                                          (b)  total loss of normally generated electrical power.
                                      In order to mitigate the risks associated with the conduct of such emergency procedures, the
                                      following should be ensured:
                                          (a)  in case of planned single-pilot operations, the crew should be composed of the
                                              commander using view-limiting devices for the purpose of simulating IMC/night and a
                                              second rated pilot whose responsibility is to help maintain visual separation from other
                                              aircraft, clouds, and terrain;
                                          (b)  the flight should be conducted in visual meteorological conditions (VMC) by day, and
                                              additional, more restrictive weather minima may be established for the demonstration of
                                              the procedures involving higher risks; and
                                          (c)  touch drills should be used when simulating a total failure of the propulsion system.
             ARO.OPS.200 GM1         Specific approval procedure
                                      LIMITATIONS FOR HELICOPTER OFFSHORE OPERATIONS
                                      The CAA may impose limitations related to routes and areas of operation for offshore helicopter
                                      operations. Such limitations may be specified in the operations specifications (OPSSPEC) or
                                      specific approved documents or in the aeronautical information publication (AIP) or by other means.
                                      For operations over sea areas, limitations may include a maximum significant wave height under
                                      which there is a good prospect of recovery of survivors. This should be linked with the available
                                      search and rescue capabilities in the different sea areas.
             ARO.OPS.200 GM2         Specific approval procedure
                                      SPECIFIC APPROVALS FOR TRAINING ORGANISATIONS
                                      The specific approvals, as established in Appendix III, for non-commercial operations and specialised
                                      operations, also apply to training organisations with a principal place of business in the UK.
             ARO.OPS.200 GM3         Specific approval procedure
                                      INSERTION OF RELEVANT INFORMATION INTO THE OPERATIONS SPECIFICATIONS
                                      When issuing the operations specifications in accordance with Appendix II, where the operation does
                                      not include helicopter operations, the helicopter-related elements contained in the operations
                                      specifications may be omitted.
             ARO.OPS.205             Minimum equipment list approval
                                          (a)  When receiving an application for initial approval of a minimum equipment list (MEL) or an
                                              amendment thereof from an operator, the CAA shall assess each item affected, to verify
                                              compliance with the applicable requirements, before issuing the approval.
                                          (b)  The CAA shall approve the operator’s procedure for the extension of the applicable
                                              rectification intervals B, C and D, if the conditions specified in ORO.MLR.105(f) are
                                              demonstrated by the operator and verified by the CAA.
                                          (c)  The CAA shall approve, on a case-by-case basis, the operation of an aircraft outside the
                                              constraints of the MEL but within the constraints of the master minimum equipment list
