Zusammenfassung:	Gas turbine engines and methods of their operation are provided. For example, a method of operating a gas turbine engine comprises selectively engaging and disengaging an engine clutch disposed between a low speed spool and a rotor assembly of the engine. Engagement or disengagement of the engine clutch is selected based on an operating condition of an aircraft comprising the engine. Further, an inter-spool clutch disposed between the low speed spool and a high speed spool of the engine transitions between engaged and disengaged, disengaging when the high speed spool reaches a speed greater than an operational speed of the low speed spool. Similarly, a gas turbine engine comprises an engine clutch configured to selectively position a low speed spool in operative communication with a rotor assembly and an inter-spool clutch configured to position the low speed spool in operative communication with a high speed spool.
