a.  
‘Take-off Power’ means the output shaft power identified in the performance data for use during take-off, discontinued approach and baulked landing and limited in use to a continuous period of not more than 5 minutes,

b.  
‘Take-off Power Rating’ means the test bed minimum acceptance output shaft power as stated in the engine type certificate data sheet, of series and newly overhauled engines when running at the declared maximum coolant/cylinder head temperatures and within the appropriate acceptance limitations.

c.  
Maximum Continuous Power’ means the output shaft power identified in the performance data for use during periods of unrestricted duration.

NOTE: It should not be assumed that maximum continuous power is necessarily appropriate to normal operations. The power to be used in such operations is a matter between the constructor and the operator.
d.  
‘Maximum Continuous Power Rating’ means the minimum test bed acceptance power, as stated in the engine type certificate data sheet, of series and newly overhauled engines when running  at the declared maximum coolant/cylinder head temperatures and within the appropriate acceptance limitations.
