E-Jets Family

Demo Flight: LNAV & VNAV

 

Welcome to Bergamo, Italy! This is my birthplace and you should absolutely visit it if you ever get a chance because it is gorgeous and most people on their way to Milano miss this absolute gem. It looks like this:

 

Initial information

Although learning how to fly a new airliner can be daunting, the E-Jets are very intuitive and straightforward planes. Many systems are automated, and the autopilot will take care of a lot of the things you’d normally have to deal with manually.

Disclaimer: This demo flight assumes that you have a basic knowledge of FMS programming. As a minimum, you should know what SIDs, STARs, and airways are.

 

What you'll learn in this demo flight

This Demo was designed to give you a quick flight around an hour long, in which you will learn:

  • How to do a full cold & dark power up and engine start

  • How to calculate the performance data using the EFB

  • How to program the flight plan using the Authentic FMS:

    • How to load a SID
    • How to load an airway
    • How to load a waypoint when there are multiple waypoints around the world with the same id
    • How to delete a waypoint
    • How to load a STAR and an APPROACH
    • How to clear a discontinuity
    • How to enter the performance data into the FMS
  • How to take off using the correct takeoff AP modes

  • How to fly the plane using LNAV and VNAV

  • How to let the FMS manage your airspeeds and autothrottle

  • How to do a DIRECT to another waypoint

  • How to do an ILS landing

Quick Tips & Notes (Please read this!)

  • The cockpit uses the Dark & Quiet philosophy, which means that if all systems are in the normal state in flight, all the buttons will be dark and there will be no aural warnings.

    Generally:

    • Dark switch = ON
    • Illuminated switch = OFF or broken.

      There are a few exceptions to this, please refer the manuals for more info.

  • You can zoom in or out on the map by rotating the knob on the pedestal under the FMS or by clicking on the range indicator on the MFD screen. We added an extra manipulator there for convenience.
  • The annunciators on top of PFD have two color schemes:

    • GREEN modes (e.g. HDG, VS, FPA) indicate manual input or operation.
    • MAGENTA modes (e.g. LNAV, FLCH, PTH) indicate that they are controlled by the FMS/VNAV.

If the autopilot start's taking you to an unexpected direction, GO GREEN!

Using your keyboard with the FMS and EFB

FMS

  • DKE (Direct Keyboard Entry) is only used for the FMS, not for the EFB or Avitab.
  • Pressing TAB (you can change this to CAPS LOCK in the settings) of clicking on the FMS scratchpad activates DKE, which allows you to type directly into the FMS scratchpad.
  • If DKE is active, you will see a small circle in the top left corner of the FMS and you will also hear beeping sounds for every keystroke. This is to make you aware you are in DKE.
  • If you want to exit the DKE mode, press TAB or click on the scratchpad section of the FMS screen until the indicator on the FMS screens disappears.

EFB

  • When using the EFB, you simply click on the screen and the edges will turn blue. That means you have focus on the screen and you can now type.
  • If you click outside of the EFB screen, the blue edge will turn off, which means the focus is no longer on the EFB screen and you can use your keyboard as usual.
  • If you are clicking on the EFB, and the screens are blue, but the EFB is not responding, try to click on the "Home button" of the EFB, or through the dropdown menu on top of the X-Plane bar, which brings up the EFB in a 2D pop-up window, and see if the input works there.

AVITAB

  • This works the same as with the EFB, except you won’t get the blue edges.
  • You can also bring Avitab up in the 2D Popup window, by clicking on the "Tablet Home button"
  • Any issues related to Avitab are out of our hands, we are simply providing avitab as it is, but if it doesn't work, that would need to be reported to the developers of it.

Navigation Data are files in X-Plane which the FMS uses to read the available procedures and waypoints around the world in order to construct the flight plans. Nav Data is updated every month, to reflect the changes tha happened to the real world navigation database.

This flight was generated using Navigation Data from March 2023 (AIRAC 2302). It is possible that some sections of the demo flight might not be up to date in the future and will not available in the FMS. In such case, please let us know and we will update the flight.

If you are not subscribed to any Navigation Data (with Navigraph or Aerosoft), you are using the default navigation data that comes with X-Plane. This data is out of date, and you may not be able to find the exact procedures of this demo flight in the FMS. You can still select the ones with similar names (usually the name of each procedure will haave a differnt number at the end of the name), however, your demo flight might be a bit different.

Demo Flight Start

1. Flight Plan

In X-Plane, load the jet at LIME, RWY 28. Our flight today is going to take us from Bergamo, Italy across the Alps to Vienna, Austria. If you don’t have the European scenery installed, you’ll still be able to fly this flight, you’ll just have oceans all around you instead of the Alps.

Our flight plan today is as follows:

LIME/28 LEGL1V.OSK1F OSKOR M985 MALUG DCT VP011 DCT EVAXI DCT ABTAN ABTA2W LOWW/BAL4N.I34
 

Created using Navigraph Charts.

 
 

Before the flight

2. Airplane Power Up & Engine Startup

To learn how to power up the airplane and start the engines, I made two videos that you can watch.

The Quick GPU & APU start goes over the basics without following all the checklists.

In this video we’ll cover all the standard operating procedures using the checklists.

 

3. FMS: Entering the Flight Plan

Please read the FMS manual, for a comprehensive explanation of the FMS operation. This Demo flight will only cover the exact steps to get you through the flight without much extra detail.

1. NAV IDENTIFICATION

  1. When you start the plane, the FMS will always be on the page RADIO page.


  2. Click in the middle of the left FMS screen, to open the FMS in the pop-up view.


  3. When the initial Radio page is loaded, pressing any of the buttons right underneath the screen will take you to the NAV IDENT page. This is where you will verify that your Nav Data is up to date.


  4. Next, we’ll go to the RTE (ROUTE) page by pressing RSK6 (right soft key next to the screen, 6th from the top).



2. DEPARTURE

  1. Hit TAB on your keyboard, this will toggle the DKE (Direct Keyboard Entry, indicated by a blue circle on the top left corner of the FMS screen) which allows you to type into the scratchpad with your keyboard.


  2. Type “LOWW” into the scratchpad and then press RSK1 to enter it as your DESTINATION


  3. CO ROUTE can be left empty


  4. (Optional) You can enter the Flight ID as well. This will then display on the RADIO page as well as the STATUS page on the MFD.


  5. Press TAB again to disable DKE, or just click on the scratchpad section of the screen with your mouse, which also toggles DKE on/off.



  6. Press RKS6 to ACTIVATE and then RSK6 again for DEPARTURE

    Note:
    The FMS was designed to naturally flow through the entire FMS setup. Generally, we will always be pressing RSK6 to progress to the next step.


  7. On the DEPARTURE page, press RSK1 to select the RUNWAY


  8. Select runway 28. You’ll then be taken to the SIDs page (Standard Instrument Departure)


  9. Press the NEXT button, to get to the next screen and select the LEGL1V SID, and the OSK1F SID transition.

    Note: If you have DKE active, you can also press the left/right arrows to navigate between pages. You can also use SHIFT + LEFT or RIGHT arrows for LSK6 / RSK6 to take you to the next (different) page.

  10. Once back on the DEPARTURE page, press RSK6 to APPLY the departure

3. ROUTE

  1. You should now be back on the RTE (route) page. This is where you’ll build your route.

    - Waypoints will be inserted into the right column labeled TO, by pressing the RIGHT soft keys below the previous waypoint.

    - Airways will be inserted into the left column labeled VIA by pressing the LEFT soft keys below the previous waypoint and then adding the exit Waypoint to the RIGHT side on the same row.


    Note: Please note that the real FMS also gives you the ability to add airways in a shorter format by typing the airway designation followed by a dot, followed by the exit waypoint, for example, “M985.MALUG”. This functionality is not currently implemented but we are working on adding it because it will definitely make things easier!



  2. Type in M985 (airway) and press LSK3





  3. Type in MALUG (airway exit waypoint) and press RSK3.





  4. Type in VP011 and press RSK4. Because there are many waypoints around the world with the identifier “VP011”, you will be taken to a new page where you need to pick the one you want.

    The list is sorted based on the distance from the preceding waypoint. We know that our waypoint is in Austria, so select the one that says “AUSTR”

    Please note that the VP011 is not an IFR waypoint, meaning it wouldn’t be used for a real-world route, however, we are only loading it so that we can demonstrate how to select a waypoint with multiple occurrences, and we will also use it to demonstrate how to delete a waypoint later.



  5. Type in EVAXI (waypoint) and press RSK5





  6. You’ve now filled the whole first page so you have nowhere to add new waypoints. Just press NEXT to go to the next page and continue there.





  7. In our case, we’ve already entered the full route, so now we just need to enter the arrival





4. ARRIVAL

  1. Press LSK6 to go to the ARRIVAL page.








  2. To select a STAR (Standard Terminal Arrival), press LSK3 and select the STAR called ABTA2W





  3. Back on the ARRIVAL page, select:

    1. Runway: 29

    2. Approach: ILS 29U

    3. Approach Transition: BAL1U





  4. Back on the ARRIVAL page, press RSK6 to APPLY the arrival





5. reviewing the flight plan

You have now entered the whole flight plan. Next, you’ll want to check the flight plan on the map to make sure you have a nice continuous route and that all waypoints were loaded correctly. 

The FMS is just a tool that tries its best to piece together the flight plan you want to fly. However, sometimes it can pick the wrong waypoints due to discrepancies in the nav data or a bug in the FMS.

Always review the flight plan on the map in the PLAN mode before you activate the flight plan in order to prevent any unwanted surprises while you're high up in the sky.

If you see that something is wrong with the flight plan, simply edit the flight plan manually until you get the route you want.

  1. Switch to the PLAN mode of the map by clicking on the PLAN on top of the MFD screen. The PLAN mode view is always centered on waypoints and it allows you to cycle through the flight plan.

    Note: The MAP mode that is centered on the aircraft and it doesn’t allow you to cycle through the flight plan.

  2. You have two ways of cycling through the flight plan:

    A. Either using the inner knob on the pedestal that is located just below the left FMS (below).

    Note: The outer ring of the knob is used to zoom in and out on the map.


    For more details, please check the Manuals and the MFD section.

  3. CHANGING THE MAP RANGE

    • This number shows the range of the white circle (half range). In this particular case, it is 20 miles.

    • This is also a hidden manipulator! You can use it to zoom in or out on the map. The official way of doing that is by rotating the knob on the pedestal under the FMS, which is also possible, but we found the manipulator on the screen much more convenient for a sim use.

    • Displays waypoint name, destination, distance-to-go, ETA/ETE, and fuel remaining based on calculations received from the FMS.

  4. CYCLE THROUGH THE FLIGHT PLAN IN PLAN MODE

    • This is another hidden manipulator. When you are in the PLAN MODE, click here (left or right, or scroll with your mouse wheel) to center on the previous/next waypoint.

B. The second and more user-friendly way is by using our custom commands which you can assign to any key on your keyboard or hardware in order to easily cycle through the flight plan.

Go to the X-Plane Keyboard settings, and in the command field, search for “xcrafts” and then in the FMS section, you’ll see two commands:

  1. Center the plan map on the next waypoint

  2. Center the plan map on the last waypoint

6. Clearing a Discontinuity

While cycling through the plan, you’ll notice that after EVAXI, the route disappears, and reappears only after ABTAN. You’ll also notice that on page 3 of the RTE, there is a DISCONTINUITY.

This is because the FMS doesn’t know how to connect the last waypoint if the route and the beginning of the STAR, this is called a discontinuity and the map shows this as a gap.

All you need to do is delete the Discontinuity:

  1. Press the DEL key, you’ll see *DELETE* on the scratchpad.

  2. Then press LSK1 next to the discontinuity to delete it

  3. The discontinuity will disappear and you can press RSK6 to ACTIVATE the route.


    Note: This is also how you would delete any unwanted waypoints.

7. Flight plan page

  1. Press the FPL button. This will bring you to the FPL (Flight Plan) page which shows a detailed view of the flight plan with additional information, like speeds or altitudes for each waypoint.

    Procedures will also be displayed as individual waypoints, as opposed to the RTE page where procedures are displayed with the procedure designation.

    You’ll see that we won’t see any data on the right side yet. This is because we didn’t enter the Performance data. To do that, let’s jump to the EFB for a moment.

 

4. EFB: Weight & Balance and Takeoff Performance calculations

1. Weight & Balance

Go to the EFB and click on the Weight & Balance tab. Here you’ll have to enter some initial data so that the EFB can calculate the performance for you.

Option 1: Fetch this data directly from your last generated Simbiref flight plan. (Make sure you have generated a flight in Simbrief before the flight!)

Click here to learn how to do that.

Option 2: If you don’t use Simbrief, you can also enter it manually. From the first dropdown select if you’d like to enter Payload or Zero Fuel Weight and enter the corresponding value.

For the purpose of this demo flight, we will enter it manually.


  1. Select Payload from the dropdown menu and enter Payload 15600lb and Block Fuel 7600lb


  2. After that enter the Fuel Weight and then press REQUEST LOADSHEET.


  3. You'll be presented with the Loadsheet which you can accept by pressing LOAD PLANE. This will actually change the X-Plane weights in the plane.


2. TAKEOFF PERF

Go to the Takeoff perf tab. This page is used to calculate Takeoff & Landing Performance data and even send it to the FMS.

  1. Fill out the input fields like this:

    • Airport: LIME

    • T/O Weight: 71 280lb

      (This is with the E175. If you are flying any other plane, find your TO weight on the Weight & Balance Loadsheet)

    • Runway: 28

    • Thrust: TO-2

    • Condition: DRY

    • Flaps: F2

    Enter the weather parameters based on your weather conditions.

    You can open the X-Plane Weather Configurator and review the wind on the ground, temperature, and Altimeter Setting (QNH). In my case it was my case, the wind was 7 knots at 357°, so we’ll enter it in the degrees/speed format as 357/7

    • Wind: 357/7

    • Temp: 18°C

    • QNH: 29.90inHg

  2. Press COMPUTE

  3. You can then enter the Vspeeds manually into the FMS, or you can send the VSpeeds to the FMS by pressing Send to FMS in the top right corner.

  • You’ll then be able to load those V-Speeds directly in the FMS in the next step

  • You can enter HPA or IN values for QNH, and the tablet will use the correct units based on your format

  • You can use the same process for landing speeds from the Landing perf page on the EFB.

 

5. FMS: Performance pages

1. PERFORMANCE INIT

  1. Back on the FMS we’ll still be on the FPL page. Now press RSK6 for PERF INIT.


  2. On the first page of PERF INIT, you can change any of the parameters, or add fuel for an Alternate Airport. We will leave it all at the default values.


  3. Press NEXT to go to PERF INIT 2/3. This is the most important page. The values entered here will calculate the vertical profile of the flight.


    1. Type in FL250 or 25000 into the scratchpad and insert it into CRZ ALT.


    2. Enter cruize winds based on your current values. We’ll enter CRZ WINDS: 253/68.

      This setting will not have a major effect on the flight plan calculations even if left at zero.


    3. Enter ZFW: 63680lb (This is with the E175. If you are flying any other plane, find your ZFW on the Weight & Balance Loadsheet)



    4. TO CG: 18.9% (This is with the E175. If you are flying any other plane, find your ZFW on the Weight & Balance Loadsheet)


      You can use the same process for landing speeds from the Landing perf page on the EFB, and PERF 3 on the TFMS.


  4. Press NEXT to go to PERF INIT 3/3. Here is where you can change the speeds for each phase of the flight. The speeds need to follow the correct format.

    • Changing the knots and mach values should be done like this: 265/0.73

    • Changing the knots only should be done like this: 265

    • Changing the mach values only should be done like this: /0.73

      In our case, we will leave them at the default values.


2. TAKEOFF PERFORMANCE

  1. Press RSK6 to go to TO DATASET which is where you can configure some extra takeoff settings. Usually, each operator has their defaults and preferences.

    We will leave them all at the default value.


  2. Press RSK6 to do to FMS TAKEOFF. This will take you to TAKEOFF INIT 2/2 which is where you can review the previous TO settings or change the flaps setting.

    We will leave everything as it is.


  3. Press RSK6 to go to TAKEOFF. Here’s where we will enter the VSpeeds which we have previously calculated using the EFB.

    You can either insert the speeds manually or you can load them through the FMS datalink. We will load them directly:


    1. Make sure that you have previously clicked on “Send to FMS” on the EFB Takeoff perf page.


    2. Press the DLK (datalink) button.


    3. If you have previously clicked on “Send to FMS” on the EFB Takeoff perf page, you will now see the landing speeds option highlighted green.


    4. Press RSK1 next to the highlighted text, which will load the vspeeds


    5. To go back, press the PERF button, and then RSK1 for TAKEOFF. You’ll now see the vspeeds populated.



  4. Set the correct flap setting based on the TAKEOFF page: FLAPS 2


  5. Adjust the airplane pitch to the PITCH TRIM setting. In my case with the E175, the PITCH TRIM was 3.5 UP. Look at the EICAS trim section, and make sure the trim also says 3.5 UP.

    Note: The TO PITCH shows what the Flight Director will show as a Takeoff Pitch. This is not what your trim setting should be.


3. DEPARTURE LIMITS

  1. Press RSK6 for DEP LIM. These settings can be left on the default values. Refer to the manual for a detailed explanation.


  2. Press RSK6 for FLT PLAN. This will bring us back to the FPL page, and we will see that all the data on the right is now populated and we can also see that the VSD (Vertical Situation Display) on the MFD shows the flight profile.

    We’re ready to take off!

 

Takeoff

6. Taxi

The engines generate enough thrust to get the plane moving even on idle. This is normal and in real life, the pilots have to apply brakes just to keep the speed within limits.

7. Before Takeoff

  1. Press TOGA on the throttles (very important). This will activate the Takeoff/Go Around autopilot modes and it will arm the lateral and vertical autopilot modes which will get engaged automatically after takeoff.




  2. Arm the Autothrottle by pressing AT on the guidance panel.


  3. Increase the ALT bug up to 10 000ft.

    Technically, you could just set it to our cruise altitude, but we will pretend that ATC told us to level off at 10000ft before reaching the LEGLO waypoint for the sake of demonstration.

  4. We have already set the correct flaps and trim pitch settings. Press the TO CCONFIG button (on top of the pedestal in front of the throttles).

    If your flap and trim settings were correct, you should hear: “DING DING DING, NO TAKOFF - BRAKES”. Indicating that the brakes are the only thing that is not configured for takeoff correctly.

    Release the brakes, and press the button again to check that you can hear: “TAKEOFF OK”

  5. Push the throttles forward. Once they are near the TOGA position, the autothrottle will get engaged and you can let go of the throttles.

  6. Take off!

8. Climb

  1. Take off, gear up, and engage AP

  2. At 400ft, LNAV will engage automatically. You will now see a magenta LNAV on top of the PFD

  3. At 1200ft, VNAV will engage automatically. You will now see a magenta FLCH on top of the PFD.

    Note: VNAV will never display as VNAV on the PFD. VNAV will always be associated with magenta FLCH (climb), magenta ALT (leveled off ), or magenta PTH (descent). Please refer to the airplane manuals for a detailed description of the autopilot mode indications.

    From this point onward, you can sit back and watch the plane climb up.

  4. At 6000ft, we will change to the standard pressure setting of 29.92inHg. In the US, the transition altitude is always 18000ft, however in Europe, the transition altitude varies and can be as low as 3,000 ft (910 m).

    Press the STD button in the middle of the BARO SET knob on the guidance panel. This will switch the altitude indications on the PFD to the FL format.

  5. Although the cruise altitude was set as 25000ft, we have set our altitude setting on the PFD to 1200ft (now shown as FL120), let’s say because the ATC told us to.

    When VNAV is engaged, the ALT setting acts as a ceiling above which the plane will not climb even if the flight plan says it should. Instead, it will go into the ALT mode and it will level off at that altitude.

    To continue the climb above 12000ft, just adjust the altitude setting to 25000ft and then press FLCH to resume the VNAV climb again.


9. Cruise

You will notice that as the airplane reaches the cruise altitude, the TRS mode will change from CLB (climb) to CRZ (cruise). At this point, increase the speed to 0.79M.

If we used the autothrottle in manual mode, we would have to adjust the speed ourselves, but since we are using the autothrottle in FMS mode, this change happens automatically.

1. Editing a flight plan

We might want to edit a flight plan by removing some waypoints from it.

  1. Press the DEL button, you will see *DELETE* on the scratchpad.

  2. Let’s delete the waypoint called VP011. Simply press the left soft key next to that waypoint on the FPL page.

2. Direct to

To skip the next waypoint and fly to any of the following waypoints, we will want to do a DIRECT to.

  1. Press the LSK next to the waypoint that you want to fly to, in our case EVAXI.

    The name of that waypoint will now appear in the scratchpad.

  2. Then insert that waypoint into LSK1 which will be the first and amber field.

When doing a direct to, the pilots are taught to Always feed amber!” (Or Amber? Just make sure the girl doesn’t get hungry!)

10. Descent

  1. One minute before TOD (Top of Descent - which is the start of descent), a vertical deviation scale will show on the PFD followed by an aural chime.

  2. At this point, you must lower the ALT setting. In our case, we will lower it to 3000ft where we will later capture the Glide Slope, but you could lower it to whatever ATC tells you or even the approach minimums.

    If you do not lower your altitude bug, VNAV will not start the descent!

  3. When you reach TOD  (also visible on the map), VNAV will go into PTH mode and it will start descending.

  4. At this point, we will adjust our descent speed to 280kts until we reach 10 000ft.

  5. Landing performance calculations:

Go to the Landingf perf tab on the EFB. We will calculate the Landing Performance data the same way we did for Takeoff.

  1. Fill out the input fields like this:

    • Airport: LOWW

    • Landing Weight: 60 000lb ************************************************

      (This is with the rough E175 landing weight in X-Plane 12. If you are flying any other plane or in X-Plane 11, your landing weight will be different. You can see your current gross weight on the Status Page on the MFD)

    • Runway: 29

    • Flaps: F5

    • Condition: DRY

    • Reverse: ALL OP

    • Wind: ************************************************

    • Icing: NO

    • Temp: ************************************************

    • QNH: ************************************************

  2. Press COMPUTE

  3. Press Send to FMS in the top right corner

  4. Back in the FMS, press the PERF button CONTINUE HERE

  5. 30NM/10000ft, change speed to 250.

    15NM/4500ft change speed to: 210knots

    13NM/3900ft : Call flaps 1, reduce speed to 180 tks

    10NM/3000ft: Set Flaps 2, then reduce speed to 160kts

    8NM/2400ft: Gear Down, Then set flaps 3, then reduce speed to 150kts

    5NM/1500ft: Set Landing Flap (Flap 5 or Full) V APP (calculated)



11. Approach

  1. As you descent below 10 000ft, lower the speed to 250kts

  2. 30nm outside of the airport, enter the correct ILS frequency to NAV1 on the FMS RADIO page (108.10) or load it through the X-Plane map.


  3. Press PREV on the guidance panel. This will display the ILS course on the HSI along with the lateral and vertical deviation cues while you’re still keeping FMS as the source for the autopilot.

  4. As you make the turn of the approach past the WW973 waypoint, you will be aligned with the approach, which you will also see on the PREVIEW needles.

    Press the APP button, which will arm the LOC (localizer) and GS (glideslope). Notice however that we are still using the FMS as the AP source, so nothing happens at this moment.

  5. Note: The real plane has the capability to automatically switch from FMS to V/L, depending on several factors. We plan to add this feature in the future.

  6. At 6000ft, press STD again to switch from the FL format to the digits format for our altitude indicator.

  7. Adjust the baro setting based on your weather conditions. Mine is at 29.90.

  8. Up until now, the FMS was the source of the autopilot. This is indicated by a magenta FMS indication on the left side of the PFD.

    To fly an ILS landing, the autopilot sourse must be VOR/LOC, in order to follow the NAV1 / NAV2 ILS frequencies.

    Switch from FMS to VOR/LOC can be done in two ways:

    1. Manually: Press the V/L button on the guidance panel once you are aligned with the localizer.

    2. Automatically: If PREV is displayed, and APP was pressed, the autopilot source will automatically switch from FMS to V/L once the GS deviation is 0.5 points or less.

  9. Once you capture the LOC and GS, you will also see APPR1 or APPR2 on top of the PFD. These depend on the BARO minimums type that you are using:

    • APPR 1: If barometric minimums is used for ILS CAT I Approaches

    • APPR 2: If radio altimeter minimums is used for ILS CAT II Approaches
