Variance Explanations	ARH System Reliance on the certification of the French Tiger variant was critical to the Australian design review and acceptance program. The DMOs ability to leverage from the French program was adversely impacted because the French program had not achieved design approval outcomes in the timeframe expected. As the ARH is a variant of the French and German Tiger helicopters, the ADF Technical Airworthiness Authority planned to utilise the existing certification work undertaken by the French acquisition agency (Delegation General Pour l'Armament). Certification of the ARH is based on the French acquisition agency as a competent certification agency and the ADF Technical Airworthiness Authority subsequently recognised the French acquisition agency as such for certification of common Tiger systems in the ARH. In doing so, the French acquisition agency certification of the French Tiger variant became an integral part of the ADF certification plan. Delays experienced in the Franco-German program directly impacted on the design development and Australian Military Type Certificate achievement. The maturity of the ARH design has required ongoing engineering changes to the approved ARH product baseline presented to the Airworthiness Board at the In Service Date. As a result, subsequent flight testing is required to confirm contract compliance and operational acceptance of incorporated design changes to enable removal of Australian Military Type Certificate and Service Release limitations. Aircrew Training Devices The Full Flight and Mission Simulator required customisation to both the visual system and the motion systems following contract signature in order to account for capability deficiencies associated with the proposed simulator design. A major cause of the delay in delivering training devices can be attributed to the efficacy with which the software provided from the aircraft manufacturer's test program is being managed to produce a high fidelity simulator.
