Part II. Flight Simulation Training Device Criteria Chapter 1. Glossary of terms, abbreviations and units II-1-3 Closed loop testing. A test method for which the flight control stimuli are generated by controllers which drive the FSTD to follow a pre-defined target response. Computer controlled aeroplane CCA. An aeroplane in which pilot inputs to the control surfaces are transferred and augmented via computers. Control sweep. Movement of the appropriate pilot controller from neutral to an extreme limit in one direction forward, aft, right or left, a continuous movement back through neutral to the opposite extreme position and then a return to the initial position. Convertible FSTD. An FSTD in which significant hardware or software, or a combination of both, are changed so that the device replicates a different model, type or variant, usually of the same aeroplane. The same FSTD platform, motion system, visual system, computers and necessary peripheral equipment can thus be used in more than one simulation. Note. The significance of the difference, as adjudged by the CAA, will dictate whether a complete separate QTG would be necessary. Otherwise, a supplemental section added to the original QTG may suffice. Correct trend and magnitude CTM. A tolerance representing the appropriate general direction of movement of the aeroplane, or part thereof, with appropriate corresponding scale of forces, rates, accelerations, etc. Critical engine parameter. The engine parameter that is the most appropriate measure of propulsive force for that engine. Damping. a Critical damping. That minimum damping of a second order system such that no overshoot occurs in reaching a steady state value after being displaced from a position of equilibrium and released. This corresponds to a relative damping ratio of 1.0. b Overdamped. That damping of a second order system such that it has more damping than is required for critical damping as described above. This corresponds to a relative damping ratio of more than 1.0. c Underdamped. That damping of a second order system such that a displacement from the equilibrium position and free release results in one or more overshoots or oscillations before reaching a steady state value. This corresponds to a relative damping ratio of less than 1.0. Daylight visual. A visual system capable of meeting, as a minimum, the system brightness and contrast ratio requirements as identified in Appendix B. Deadband. The amount of movement of the input for a system for which there is no reaction in the output or state of the system observed. Device qualified as T only. Training on this FSTD type may be credited towards the issuance of the associated licence, rating or qualification. Device qualified as TP. Training on this FSTD type may be credited towards the issuance of the associated licence, rating or qualification and should include all tasks to the level of proficiency required. Testing and checking can additionally be conducted provided that training-to-proficiency has also been completed on a device qualified to the same level. 28/10/16 Corr. 1
Manual of Criteria for the Qualification II-1-4 of Flight Simulation Training Devices Volume I Driven. A test method where the input stimulus or variable is driven or deposited by automatic means, generally a computer input. Engineering simulator validation data. Validation data generated by an engineering simulation or engineering simulator that is acceptable to the CAA. Evaluation FSTD. The careful appraisal of an FSTD by the CAA to ascertain whether or not the criteria required for a specified qualification level are met. Fidelity level. The level of realism assigned to each of the defined FSTD features. Fidelity level G. Where the fidelity level is G, the initial validation should be based on subjective evaluation against approved data, where available, complemented if necessary by approved subjective development, to determine a reference data standard. Recurrent validations should be measured objectively against the reference data standard. Fidelity level N. Where the fidelity level is N, the FSTD feature is not required. Fidelity level R. Where the fidelity level is R, the initial validation should be based on objective evaluation against approved data, complemented if necessary by approved subjective development, to determine a reference data standard. Recurrent validations should be objectively measured against the reference data standard. Note. Fidelity level R1 is defined in Chapter 2, 2.2.6.3. Fidelity level S. Where the fidelity level is S, the initial and recurrent validation should be based on objective evaluation against approved data. Flight simulation training device FSTD. A synthetic training device that is in compliance with the minimum requirements for FSTD qualification as described in this manual. Flight test data. Actual aeroplane data obtained by the aeroplane manufacturer or other approved supplier of data during an aeroplane flight test programme. Footprint test. A test conducted and recorded on the same FSTD, during its initial evaluation, to be used as the reference data standard for recurrent evaluations. In the event of an approved change to the FSTD to the flight model, or flight control system that may alter its characteristic, the CAA may require that the footprint test result be re-generated under the new conditions to form a new reference data standard. Note. See also definition of master qualification test guide MQTG. Free response. The hands-off response of the aeroplane after completion of a control input or disturbance. Frozen/locked. A test condition where a variable is held constant over time. FSTD approval. Declaration of the extent to which an FSTD of a specified qualification type may be used by an FSTD operator or training organization as agreed by the CAA. It takes account of differences between aeroplanes and FSTDs and of the operating and training ability of the organization. FSTD data. The various types of data used by the FSTD manufacturer and the applicant to design, manufacture and test the FSTD. FSTD feature. Describes the characteristics of an FSTD for each of the thirteen categories that have been used in this manual to define the general and technical requirements for FSTDs.
