 Engine fuel is controlled by two Fuel Control Units, one on each engine. The fuel control units are hydro-mechanical control units that control engine speed by adjusting the fuel flow to each engine. Each fuel control unit consists of two sections, a metering section and a computing section. The metering section receives filtered fuel from the fuel filter and delivers it to the engine, adjusting the fuel flow rate according to the signals from the computing section. The computing section is a mechanical device that takes the signals for power turbine speed(N2) and engine control lever position and determines the proper fuel flow to the engine to maintain that speed and signals the metering section how much fuel to deliver to the engine. As load is applied to the engines, the engine speed will start to drop, the fuel control unit will sense this drop and apply more fuel to return engine speed to the selected value. There may be a momentary lag as the fuel control unit reacts.

 Ignition switches are located on the lower left side of the upper console.  There is one three position rocker switch for each engine.  The ignition system is powered by the DC bus.  In the center OFF position, the engine igniters are deenergized. A spring-loaded TEST position for each rocker can be used to test the igniters.  When held in the TEST position with DC power active, a clicking sound will be heard.  The igniters should never be tested except when the engine control levers are in the SHUT OFF position, the starters are not running, and the engine fuel values are closed.  In the NORM position, the igniters will activate while the starter is running.  This position should be used for normal start and while engine is operating.

 An external power port is located at the front of the aircraft on the right-hand side (see <xr id='fig:extpwr'/>).  A Ground Power Unit (GPU) can be connected to this port to provide DC and AC power on the aircraft.  In addition to connecting the ground power unit, the EXT PWR switch in the cockpit must also be ON in order for external power to be available in the aircraft.  To recharge the battery, the BATTERY switch must also be on.  When external power is connected and turned on a green EXT PWR advisory light will illuminate in the cockpit.

 The S-61R is equipped with a rear ramp consisting of two independently controllable sections, the forward ramp and the aft ramp.  The forward ramp hinges directly to the floor of the helicopter, extending the main cabin floor area when the ramp is in the up position.  The aft ramp shares a hing on the aft side of the forward ramp.  When both ramps are in the closed position, the helicopter aft cabin is closed off by the ramp.  When both ramps are in the open position, the ramp can be used for loading the helicopter.  There is also an emergency release for the aft ramp that allows it to be used as an emergency exit.  The ramp system operates off the utility hydraulic system.  The ramp can be controlled from a panel next to the pilot on the middle console or through a panel in the aft area of the aircraft. The Aft ramp may be opened in flight or on water, the forward ramp may only be opened on the ground.

−	The Shergood S-61R is a twin-turbine engine helicopter designed for transportation of cargo and for search-and-rescue operations in day, night, visual and instrument conditions. The helicopter is powered by two 1,400 shp General Electric T58-GE-10 turbo-shaft engines mounted above the main cabin in front of the main transmission. Drive shafts from each engine is connected to the main transmission through a mixing unit such that the rotors will continue to spin even if one engine fails. When the rotors are not turning, an APU (~~Auxilary~~ Power Unit) can be used to supply electrical power and hydraulic pressure. Fuel is carried in compartments in the lower hull of the helicopter with forward and aft ~~auxilary~~ and main tanks. An entrance door is located on the forward right side of the main cabin, while a hydraulically powered ramp is in the back. The helicopter is fully amphibious with a "flying boat" style design.	+	The Shergood S-61R is a twin-turbine engine helicopter designed for transportation of cargo and for search-and-rescue operations in day, night, visual and instrument conditions.
