Just another student........
Kudos.......thats the ONLY ( and best way ), to check it.....!!!! Do the before take off checklist as Msrs Boeing recommended it.......right BEFORE you move on own power!!! Reason being minimal runway and taxiway incursions during taxying due the "pseudo" feeling of "all checklists complete". Also maximum focus on ground ops and taxying.......a MAJOR cause of all ground incidents..........DUH......
