CS-E 770 Low Temperature Starting Tests ED Decision 2007/015/R (See [AMC E 770](#_DxCrossRefBm1371447802)) (a) The Engine must be shown to be capable of satisfactory starting and acceleration from the appropriate minimum temperatures declared by the constructor, and demonstrated as indicated in CS-E 770(b) and (c). Unless otherwise agreed, the temperature indicated for service use should be the oil temperature. (b) *Minimum Engine Carcass/Oil Temperature for Starting.* Evidence must be provided that Engine starting with the Engine carcass and oil at the declared minimum temperature using the minimum and maximum starting torques declared for service use, is feasible and will not damage the Engine. If a non-standard starting procedure is necessary below a certain temperature, this must also be established and the relevant details must be quoted in the Engine operating instructions, in addition to the standard procedure. (c) *Minimum Oil Temperature for Acceleration.* Evidence must be provided that, with the Engine oil at the declared minimum temperature for the selection of Take-off Power or thrust, smooth acceleration of the Engine is obtained without Engine damage when the power or thrust control lever is moved from the ground idle position (minimum test bed idle for rotorcraft Engines) to the position appropriate to takeoff in a time not greater than one second.
