‘Minimum Drainage Period After a False Start’ (turbine engines) means the minimum period necessary to allow surplus fuel to drain from the engine prior to making a further attempt to start the engine. The period is measured from the time at which the starter is switched off and/or the engine fuel cock is closed during a false start. ‘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. ‘Modified Engine’ means an engine, previously approved, in which hitherto unapproved modifications have been embodied. ‘Modified Propeller’ means a propeller previously approved, in which hitherto unapproved modifications have been embodied. ‘Module’. An engine (or propeller) Module is a group of engine (or propeller) components defined by the constructor and designed to be replaceable without mechanical or performance difficulties. It is uniquely identified and amenable to the setting of an overhaul life separate from other parts of the engine (or propeller). ‘New Engine’ means an engine which has not been subjected to in-service operations, essentially identical in design, materials and methods of construction with one which has been type certificated. ‘New Propeller’ means a propeller which has not been subjected to in-service operations, essentially identical in design, materials and methods of construction with one which has been type certificated . ‘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. |
