PFD (Primary Flight Display)- The PFD displays all the critical flight environment information. Here you will see the aircrafts attitude (pitch and bank). The airspeed and altitude. The heading and autopilot inputs.

MFD CONTROL PANEL- This is where the many features of the MFD (Multi Function Display) are controlled.
The MFD control panel consist of 3 sections, the rotary switch on the left is to select the type of display on the MFD. There is LS (Landing System), VOR, NAV, ARC and Plan. These will be described in detail below. The rotary knob on the right is to select the range of the display of the flight plan when in the PLAN mode. These are in NM (Nautical Miles) 10 thru 320. The buttons along the top are to select the items which are displayed in the flight plan when in the PLAN mode. CSTR is for the course track of the flight plan. WPT will display all the intersections within view of the plan. ARPT will display the airports, VORD displays the VOR and DME stations. The NDB displays the ADF stations.
LS is for the Landing System display. This will give you a large and easy to read display of the ILS (Instrument Landing Systems) Vertical (course) and Horizontal (glide path) Bars. The dark blue needle points to the ADF station if being received. The light blue triangle is your Autopilot Heading Bug.
VOR gives you a large easy to read indicator of where the tuned in VOR stations are in reference to the aircraft. This is very handy for setting up approaches.
The NAV selection gives you a indication of your reference to the in flight navigation aids. The NAV 1 OBS needle shows the omni radial selected for VOR 1. This is selected by the Nav1 OBS Course Adjuster (3). The CDI (Course Deviation Indicator) bar shows your position in reference to the selected radial. NAV 2 points to the location of VOR 2 in reference to the aircraft. The ADF needle points to the tuned in NDB.
ARC is like the NAV selection except it is presented in a close up view. The indicators are similar and have the same functions as the NAV display. There is the added feature of a Track Indicator, this indicates the aircrafts current track along the ground. This takes the aircrafts present bearing and add the effect of the winds on the aircraft.
The PLAN display shows you the reference of the aircraft to the filed flight plan of the current flight. The area represented in the Plan Display is selected by the Range rotary switch. It will display in 10, 20, 40, 80, 160 and 320 Nautical Miles. The range setting is shown below the aircraft indicator when in PLAN display mode. The picture below shows how the different items in the plan is represented.
Note: Additional MFD information will follow below.
12. MFD (Multi Function Display)- Most of the feature of the MFD where covered in above under the MFD Control Panel. Some of the other features are shown here. These features are found on all the MFD selected displays.

2. True Airspeed | 11. Local time on reaching the next waypoint |
3. Wind Vector Component | 12. Vor 1 Needle style |
4. Wind Velocity | 13. VOR station tuned to NAV 1 |
5. Indicates if NAV 1 is to the VOR or GPS | 14. NAV1 DME |
6. Current Heading | 15. Aircraft reference indicator |
7. Indicates if Approach Hold is active | 16. NAV2 DME |
8. Next waypoint in the flight plan | 17. VOR station tuned to NAV 2 |
9. Bearing to the next waypoint | 18. Vor 2 Needle style |
