	The '''Translation Hand Controller (THC)''' provides the capability of manual commanding simultaneous accelerations along the spacecraft axes, that means translational manoevers. It is also used to initiate several transfer commands, to transfer the spacecraft control from CMC to SCS control for example. The real THC is basically a kind of joystick, but with some significant differences. The main functions are simulated by using an joystick or Orbiter's ~~attitude~~ controls configured with the [[Launchpad Configuration Options]], for some functions the panel is used.

			== Quickstart Mode ==

			In ''[[First Steps#Quickstart Mode\|Quickstart Mode]]'' the THC isn't used, but the [[CSM RCS]] is controlled by Orbiter directly as for example in the Delta-glider including the navmodes (killrot etc.), external control by MFDs etc. So this article applies in ''Virtual AGC Mode'' only, but optionally Orbiter control can be disabled with the [[Launchpad Configuration Options]] for ''Quickstart Mode'', too.

	Translational control is provided by ~~joysticks~~ or Orbiter's ~~attitude~~ controls~~. In case of joysticks,~~ the [[Launchpad Configuration Options]] ~~allow the use of one or two joysticks. If only one joystick is configured, it acts as [[RHC]] or THC depending on Orbiter's attitude control mode~~.		Translational control is provided by a joystick or Orbiter's controls as configured with the [[Launchpad Configuration Options]]. Unlike the [[RHC]] the axes of the real THC are different to the axes of a joystick. The following table shows how the joystick axes are related to the translational movements with respect to the astronaut in the spacecraft:

	With the '''"Use Orbiter controls as RHC/THC"''' option enabled in the [[Launchpad Configuration Options]], the Orbiter controls (keyboard, joystick etc. as you have configured it) are used as input for the THC while in Orbiter's linear attitude mode. In this case Orbiter's joystick axes and keys assignments to the translational movements of the spacecraft apply.

	With this option disabled, translational thruster firing with the [[w:numeric keypad\|numeric keypad]] or a joystick enabled in Orbiter is possible but unrealistic. In this case Orbiter controls the thrusters directly without using the auto or direct thruster control coils, so this is still working without electrical power, disabled coils etc. The RCS thrusters still need proper fuel supply though.
