+**EFIS Control Panel**
+The Electronic Flight Instrument System Control Panel (EFIS Control Panel) can be found forward and left of the throttle quadrant. It has knobs and buttons to control the PFD as well as the MFD (Multi Function Display).
+{{ :wiki:q400_efis_control_panel.jpg?350|}}
+   * Mouse over the left or right Bearing knob (BRG) to display bearing needles from different sources on the HSI.
+   * The current selection made is displayed in the lower left and lower right corner of the PFD as a legend. In the OFF position no needle is displayed at all.
+   * AUX1 and AUX2 are not installed
+   * FMS1 and FMS2 require a flight plan to be near by
+   * VOR1 and VOR2 cannot display a bearing to an ILS
+   * ADF needles are parked at 3 o'clock (90° off to the right) when no signal is received.
 ==== MFD ====
+The Multi Function Displays (MFDs) in the Q400 are capable of rendering different pages that a pilot can chose from. The selection of the pages is done with the Engine and System integrated display Control Panel (ESCP) and the adjustment of the navigation display (map) is done with the Electronic Flight Instrument System (EFIS) control panel. For example, you can zoom in on the map, display the localizer deviation or the flight plan, you can visit system pages or display the PFD or ED instead (display swap).

+**ESCP**
+The Engine and System integrated display Control Panel (ESCP) (what a name! I'm not writing that again :-P) is found in the pedestal aft of the throttle quadrant, right behind the TRIM panel.
+The knobs in the top left and top right of the ESCP panel are the **MFD1** and **MFD2** revision selectors which each have 4 options: PFD, NAV, SYS and ENG and control the left and right side MFD mode.
+   * Move you mouse cursor over the knobs and rotate them with the mouse wheel.
+With the selector in **PFD** the MFD displays the primary flight display, e.g. in case the left screen is broken.
+In **NAV** the navigation display is displayed.
+{{ :wiki:q400_escp.jpg?350|}}
+**SYS** displays a system page. With the pushbuttons in the center of the panel the different pages for electrical systems (ELEC SYS), engine systems (ENG SYS), fuel system (FUEL SYS) and doors page (DOORS SYS) can be visited. With the "ALL" button the pages are stepped though, one at a time per click.
+   * Mouse over the MFD2 selector and your your scroll wheel
+   * Click a button in the center to change the page
+With the selector in **ENG** the engine display is displayed on the MFD in case the center screen is broken for example.
+**EFIS Control Panel**
+When the MFD revision selector is in the NAV mode (default Aerofly setting for both MFDs) then the navigation display (ND) is shown on the MFD.
+{{ :wiki:q400_efis_control_panel.jpg?350|}}
+   * Left click the FORMAT button to view the **FULL MODE** of the navigation display, a north up plan mode
+   * Right click the **FORMAT** button to simulate a press and hold for 1 second. This option hides the flight plan and displays the localizer deflection instead.
+   * Mouse over the **RANGE** knob and rotate your scroll wheel to increase or decrease the range on the map. Scroll down to close in on your aircraft, scroll up to increase the range and see further into the distance
+   * Click the **DATA** button multiple times to show navigation aids (NAV), airports (APT), both (NAV & APT) or neither on the map
+==== ED ====
+The Engine Display shows the most important engine related parameters. It is located in the center of the flight deck to be visible easily by both pilots.
+{{ :wiki:q400_ewd.jpg?350|}}
+   * Top left and top right: Engine **Rating**, name and maximum torque percentage.
+   * **TRQ** - current torque percentage which indicates the current power created by the engines as a percentage of the current rating. **Note** - 100% with 850 RPM is creates less power than 100% with 1020 RPM. The actual power output of the engine is the product of propeller rotation speed and torque!
+   * **NH** - The High pressure rotation speed is the engines most inner core rotation speed, high pressure compressor and turbine shaft rotation speed. Displayed as fraction of maximum design speed.
+   * **PROP**/**NH**: Propeller Rotation speed in rotations per minute. On the ground RPM is maintained at 660RPM, during takeoff MAX 1020 RPM is used
+   * **FF** - Fuel Flow consumed by the engine, in kilogram per hour.
+   * **ITT** - Indicated Turbine Temperature in degrees Celsius
+   * **NL**: Low Pressure rotation speed, outer core engine low pressure compressor and turbine shaft rotation speed. Displayed as fraction of maximum design speed.
-==== EWD ====
+Other parameters displayed are: Oil temperature and pressure, fuel in each wing tank and the fuel temperature, Static Air Temperature (SAT).
+The display also displays "REDUCED NP LANDING" at the top (described further down) and the status of the autofeather "A/F SELECT" or "A/F ARM" under specific conditions.
 ==== Overhead Panel ====

 VNAV PATH will engage once the vertical profile is intercepted. To intercept use any other vertical, e.g. vertical speed and either increment the descent rate if you are above profile or reduce sinkrate or even level off when the vertical deviation shows that the flight plan is above you.
+==== Warning Sounds ====
+The Q400 has a lot of warning sounds and if you have played around with it in Aerofly already you probably heard at least three or four of them.
+**Gear Warning**
+A constant medium pitch beep sound is heard when the aircraft logic circuits think it should the gear should be down in the current configuration. Often this warning is heard when the power is reduced to idle low to the ground.
+Extend the landing gear by either clicking the lever in the cockpit or pressing your button or key assignment (default key: "g").
+**Beta Warning Horn**
+When the power levers are retarded below the FLT IDLE detent in flight a loud alternating high-low pitch warning sound is heard (oioioi...). This warning indicates that you should increase your throttle lever until it snaps into the FLT IDLE position. Since the Q400 is equipped with propellers that can pitch flat (DISC 90° to flight direction) and even backwards (REV) to create reverse thrust it is not a good idea to try and pull the power levers aft of the flight idle where they could act as two circular 4.1 m diameter airbrakes.
+Keep the power levers above FLT IDLE during the entire flight. Also, during flare, don't reduce the power to FLT IDLE, keep the power in during the flare to avoid falling from the sky.
+**Altitude Alert**
+When approaching the selected altitude a high pitch beep sound can be heard. This is just alerting the pilots that the aircraft will level off in about 1000ft and that the pilots should be ready to re-adjust the power, since the Q400 doesn't have an auto throttle system. When the selected altitude is flown through and the aircraft wasn't leveled out the sound is triggered again 250ft below or above the selected altitude as to warn pilots they are diverting from the selected altitude.
+When flying around for fun or are currently resetting the selected altitude just ignore this warning. When the autopilot is flying make sure that "ALT SEL" is armed in white so that the altitude capture function is activated when you hear this sound. Then adjust the power once the altitude captures.
+If you fly on autopilot and hear the warning two times in a row you probably just shot through the selected altitude. Make sure to arm "ALT SEL" next time. For now you have to change the vertical mode to get back to altitude.
+**Pitch Trim**
+When the pitch trim is moving for more than two seconds a constant ticking sound is heard to warn the pilots of a potential pitch trim run away.
+If you are manually holding the pitch trim button release the button for a second to stop the warning or just ignore it until you are finished trimming.
+**Stall Warning**
+When the aircraft's speed is low (in the red low speed area) or the angle of attack is too high the stick shaker triggers which is audible as a rattling sound.
+Reduce the angle of attack by reducing back pressure on the yoke and add power to increase airspeed.
+**Overspeed**
+A constant medium pitch beeping sound is set off when you exceed the maximum operating speed of the Q400. This maximum speed changes with the altitude. Look at the PFD speed tape and notice the red overspeed tape.
+Gently pull on the yoke to recover from the overspeed and/or reduce the power lever position to FLT IDLE. Check the speed chart on the left side window frame for more the maximum operating speeds under certain conditions and with individual configurations.
+**Takeoff Configuration Warning**
+On the ground a medium high pitch pulsing warning is triggered when the power levers are advanced for takeoff power and the aircraft configuration is not okay for takeoff.
+  * Check your flap position, it should be between 5 and 15 degrees for takeoff.
+  * Set the PROP levers to MAX 1020. **Note** When ever you are on the ground and are currently not in the process of shutting down or starting the engines leave the PROP levers at 1020.
+  * Center your tiller, a large deflection of the nose gear is seen as a problem.
+**Master Warning & Caution**
+A short medium pitch beep is heard when a caution goes off. This is accompanied by a flashing master caution light on the right side of the glareshield. Click the warning light to stop the flashing and look up to the caution and warning panel (underneath the overhead panel) to read the caution message.
+A tripple ding is heard when a master warning is triggered. Immediately check the warning panel.
+When you shut down either engine a few master warnings are to be expected. The usually can be ignored when you are on the ground.
