 The hat-switch below and to the right of that controls the pitch trim and roll trim. When the autopilot is engaged these buttons forward commands to the autopilot and can change the pitch angle, selected airspeed, selected vertical speed, altitude currently held or the bank angle, selected heading depending on the active autopilot modes.
+  * You can assign the airplane elevator and aileron trims in the general section of the controller setup to control this hat-switch and to control these trim inputs with your joysticks.
+==== Engine Main and FADEC Switches ====
+In the front panel in the lower left center section you can find the engine 1 and 2 MAIN switches, labeled OFF, IDLE and FLIGHT as well as the FADEC switches.
+ENG 1/2 MAIN switches:
+  * OFF - The engine shuts down, fuel is removed
+  * IDLE - The engine is automatically started and spools up to idle and then maintains a rotor speed between 72 and 74%. When the engine was in flight mode before it spools down to idle.
+  * FLIGHT - The engine accelerates the rotor to around 100%. The FADECs change the engine core speed to maintain a constant rotor speed when you change the collective pitch input
+The FADEC switch turn the FADECs off when the engine has stopped. When the engine is still running the FADEC stays on but in a less redundant operating mode.
+To override the FADEC fuel flow to the engine you can rotate the twist grips on the collective pitch lever.

+==== MCDU ====
+Navigation and communication frequencies can be changed with the Multifunction Control Display Unit (MCDU).
+  * Push the FREQ button to access the radio page. It should already be displayed per default.
+As an example we will now tune a frequency for the NAV 1 receiver. All other frequencies are tuned in a similar fashion.
+  * Enter the frequency you want to tune with the number-keypad. The entry appears in the scratchpad at the bottom of the MCDU screen.
+  * Press the line select key on the right where you want to enter the frequency. This will set the standby frequency of the receiver.
+  * Transfer the frequency to the active side on the left by pushing the associated line select key on the left hand side, in this case "<- NAV1"
