    Looking at the STS-111 ascent time line at:
    
    http://www.spaceflightnow.com/station/sts111/fdf/111ascenttimeline.html
    
    I notice T+02:14 Start OMS Assist and T+03:37 End OMS Assist so the OMS
    is used during the ascent.  Whether this is the OMS-1 burn or if that
    still exists for contingencies later in the ascent I don't know.
