GM1 SIMD.100 Scope of validation source data

(a)     The ‘additional features’ as mentioned in CS SIMD.100 may be composed of the applicant’s additional requirements along with the Certification Specifications for Flight Simulator Training Devices (CS-FSTD) requirements. These may consist of additional data to support tests other than the objective validation tests required for the qualification of the FSTD. For example, data to support:

—          specific aircraft operation profiles (e.g. steep approaches); or

—          validation source data (VSD) from theCertification Specifications for Flight Crew Data (CS-FCD) requirements related to training areas of special emphasis (TASE), impacting the specification of the FSTD; this may be the case for particular aircraft systems or manoeuvres in normal or abnormal conditions that require specific skills to be trained (e.g. use of specific aircraft systems, application of specific procedures in case of systems malfunctions, degraded control laws, etc.); or

—          reference to installed equipment; or

—          specific aircraft configurations (e.g. the avionics configuration and capability or the navigation software configuration and specific features).

The data provider should define objective tests in relation to the additional features that are needed to be demonstrated on the FSTD and discuss the conditions for those tests with EASA as soon as the need for those tests is identified.

If data that does not come from an aircraft type certificate (TC) applicant/holder but from an organisation that holds an EASA supplemental type certificate (STC) (see GM2 SIMD.200) is used, the ‘additional features’ that are included by that organisation should contain at least those already identified by the TC applicant/holder.

(b)     The scope of the VSD is to be included in the validation data roadmap (VDR). CS SIMD.200 and GM5 SIMD.200 provide further guidance material, thus becoming part of the TC or STC.

The scope of the VSD should be technically verified by the  EASA(see explanatory diagram below and GM3 SIMD.200).

Point ①: see GM2 SIMD.200 for details related to the TC applicant.

Point ②: see GM1 SIMD.120 for details related to the VSD.

Point ③: see GM5 SIMD.200 for details related to the VDR.

Point ④: EASA is responsible for the technical verification of compliance against CS-SIMD. If a national aviation authority (NAA) is the competent authority for the evaluation of the FSTD, that NAA may support EASA in the technical verification.

The definition of ‘competent authority’ is included in ORA.GEN.105 of Regulation (EU) No 1178/2011 (the ‘Aircrew Regulation’).

Point ⑤: see GM3 SIMD.200. If and when applicable, the technical verifications include, for example, the following elements at the data provider’s level:

—          the implemented processes;

—          the simulator data production and processing plan (in relation to the aircraft certification process);

—          the simulation methods;

—          the simulation itself;

—          the models that are established by the data provider;

—          the capability to produce the validation data (VD) and the content of the VDR; and

—          the configuration control process during the life cycle of the aircraft (e.g., changes to the avionics, flight control laws, etc).
