It is a theorical question based on the RFM part II, section I System Descriptions. Pg. 1-11.
"The 30-second light has the additional function of annunciating that 30-second usage has been recorded. The occurrence of 30-second usage is latched by the DECU and reported by the illumination of the amber light when the engine is not running."
So I want to know if it is possible to start the engine in that condition, when the 30 sec. OEI ball is displayed, caused by a 30-second OEI power usage in the last flight. If starting the engine in these conditions is not possible, what would have to be done to clear the ball out?
