Climatic conditions: a. The standard climatic conditions are intended primarily for use in designing aircraft structure and equipment which should remain airworthy when subjected to the appropriate conditions. b. Aircraft performance will vary considerably within the defined climates. It is not intended that any one stated performance should be achievable throughout the whole envelope of conditions but rather that sufficient performance data should be scheduled for an operator to determine the performance which will be achieved in particular conditions. c. The climatic conditions given are conditions of the free atmosphere. The temperatures achieved in an aircraft in these atmospheric conditions may be considerably higher. In the absence of precise information as to the surface finish, ventilation and type of engine, etc., the following maximum ambient temperatures should be assumed: ‘Continuous OEI Power and/or Thrust’ means the power and/or thrust identified in the performance data for use after take-off when a power-unit has failed or been shut down, during periods of unrestricted duration. ‘Continuous OEI Power and/or Thrust Rating’ means the minimum test bed acceptance power and/or thrust, as stated in the engine type certificate data sheet, when running at the specified conditions and within the appropriate acceptance limitations. ‘Control Mode’ (Engine related definition) means each defined operational state of the Engine Control System where satisfactory Engine control can be exercised by the crew. [Amdt. No.:Def/1] ‘Covered Fault’ means a Fault which is detected and accommodated. [Amdt. No.:Def/1] ‘Critical Engine’ means the engine whose failure would most adversely affect the performance or handling qualities of an aircraft. |
