It refers to the throttle setting. Nominal thottle setting is 104.5%, but the Block II SSMEs can go all the way up 109% if needed. So '''Single engine 104''' means that nominal MECO targets with a single engine running at 104.5% nominal thottle setting.

====How do you control the main engines?====
 
 
The nominal operation mode is fully automatic, controlled by the GPCs. But the speedbrake/throttle controllers allow manual take over in emergency. This operation requires pressing a button on the controller and move the throttle controller to the current automatic power setting and release the take-over button. If you have moved the controller to the right setting (For example, 104%), indicators on the forward panel light and indicate that you now have manual control.
 
 
Additionally, there are a number of switches and pushbuttons to manually cut off the SSMEs and manage the main propulsion system, for example power-down the controllers or manually initiate propellant dump and inert sequences after MECO.

The orbiter is usually controlled automatically by the [[GPC|GPCs]] except during landing and some orbit maneuvers (eg docking). Manual control is possible by using [[Rotary hand controller|rotary hand controllers]] and [[Translation hand controller|translation hand controllers]], which can be used in many different operation modes.

Also during rendezvous with the [[International Space Station]], the orbiter will do a 360° pitch-around manuever that will allow the ISS crew to photograph the TPS that will later be downlinked to the ground.
