GM1 ARA.FSTD.130 Changes

QUALIFICATION OF NEW TECHNOLOGY OR SYSTEMS

Where an update to an FSTD involves a change of technology or the addition of a new system or equipment that is not covered by the qualification basis used for the existing qualification, an evaluation of such changes may not be possible using this original qualification basis. For these cases, the specific changes can be qualified by using newer Certification Specifications, new AMCs or alternative means of compliance, that apply to these changes, without affecting the overall qualification of the FSTD. This approach should be documented.

GM1 ARA.FSTD.130 Modifications

SPECIAL EVALUATION CONSIDERATIONS FOR FSTD WITH FCS

AIRCRAFT SIMULATION FEATURES

(a) The aircraft simulation group of FSTD simulation features comprises, amongst others, ‘Performance and handling on ground’, ‘Performance and handling in-ground effect’, ‘Performance and handling out-of-ground effect’, ‘Flight control forces and hardware’ and ‘Flight control systems operation’. Changes to fidelity levels of these features usually directly affect handling and performance qualities and will result in updates to the QTG that may justify an in-depth special evaluation covering objective as well as subjective testing.

(b) Aircraft simulation also includes the features ‘Flight deck layout and structure’ as well as ‘Aircraft systems’. Changes to fidelity levels of these features certainly require functions and subjective testing but may still require updates to the QTG documentation for general requirements and statements of justification, even if there are no objective validation tests affected.

CUEING SIMULATION FEATURES

(c) The cueing simulation FSTD group of features comprises ‘Visual cueing’, ‘Motion cueing’, ‘Vibration cueing’ and ‘Sound cueing’. Changes to fidelity levels of all these cueing features will likely impact the QTG general and objective testing requirements and will require both objective and subjective testing at the discretion of the competent authority. Some visual cueing feature updates may comprise mirror replacement and/or projector replacements for which the competent authority may not require a special evaluation unless the FCS is affected.

ENVIRONMENT SIMULATION FEATURES

(d) The environment simulation FSTD group of features comprises ‘Navigation’, ‘Atmosphere and weather’ as well as ‘Operating sites and terrain’. Changes to these feature fidelity levels will probably only require functional and subjective testing.
