## CS-E 360 Detonation Tests

For spark ignition Engines:

(a) A test shall be conducted to demonstrate that the Engine can function without detonation at all operating conditions within the flight envelope. If the design of the ignition system includes redundancy, this test shall be repeated in degraded operating modes.

(b) During the test of CS-E 360(a), the Engine shall be operated throughout the range from the lowest Engine rotational speed intended to be used for cruising, to the declared maximum Engine rotational speed, at the conditions of power setting, mixture setting (if applicable), oil temperature, coolant or cylinder-head temperatures, and manifold air pressure and air temperature, most likely to cause detonation. An agreed method shall be used to determine the degree of detonation.
