                                ‘Maximum Power-turbine Over-speed’ means (applicable only to free power-turbine engines for helicopters) the maximum rotational speed of the free power-turbine, inadvertent occurrence of which for periods of up to 20 seconds, has been agreed not to require rejection of the engine from service or maintenance action (other than to correct the cause).
                                 
                                ‘Maximum Power-turbine Speed for Autorotation’ (applicable only to free power-turbine engines for helicopters) means the maximum rotational speed of the power-turbine permitted during autorotation for periods of unrestricted duration.
                                 
                                ‘Maximum Governed Rotational Speed’ (variable pitch (governing) propellers) means the maximum rotational speed as determined by the setting of the propeller governor or control mechanism.
                                 
                                ‘Maximum Permissible Rotational Speed’ (fixed, adjustable or variable (non-governing) pitch propellers) means the maximum propeller rotational speed permitted in normal or likely emergency operation.
                                 
                                ‘Maximum Propeller Overspeed’ (20 second) means the maximum propeller rotational speed, inadvertent occurrence of which for periods of up to 20 seconds, has been agreed not to require rejection of the propeller from service or maintenance action (other than to correct the cause). 
                                 
                                ‘Minimum Governed Rotational Speed’ (variable pitch (governing) propellers) means the minimum rotational speed as determined by the setting of the propeller governor or control mechanism . 
                                 
                                ‘Minimum Take-off Crankshaft Rotational Speed’ (piston engines) means the minimum crankshaft rotational speed permissible for use with the maximum take-off manifold pressure.
                                 
                                ‘Normal operating differential pressure’ means the pressure differential between the cabin pressure and the outside ambient pressure, including the tolerances of the normal pressure regulating system.
