Slash RULE o When entering data on a line that has

more than one value (wind direction/wind speed) the slash is used to seperate entries. It must be used.

o Example: To enter both wind speed and direction one would enter" 215/35" for a 35 knot wind and 215 degrees.

o Example: To enter the wind speed only, one would enter "/35"

o When entering the first item only the slash is not required.

The FMC allows a few "hidden" scratchpad operations to add to your convenience. These functions are changing FMC lighting, changing the power state, and viewing the TUTORIALS menu.

Changing FMC Lighting o To change the FMC lighting type the

following into the scratchpad... DAY NIGHT NIGHT OFF NIGHT LIGHT Press EXECute when ready to set lighting

The following boxes are examples of what will be seen throughout the rest of the manual. The boxes describe the information that will be provided in the actual title boxes in the manual.

These pages selectively display data using a common format for each of the four standard descent modes: Path descent-Best ECONomy or any manually selected descent speed, and Speed descent-Best ECONomy or any manually selected descent speed.

Speed descents are altitude and airspeed constrained but require vertical path control using thrust levers and speedbrakes. If the MCP has already been set to a lower altitude, the V NAV speed descents are automatically initiated at the computed top-of-descent. FMC predictions assume a computed profile to 1000 feet above the destination field elevations at a position which will vary according to selection of arrival procedures. A slowdown profile for approach will be provided by the FMC. L NAV does not need to be engaged to fly a VNAV SPEED DESCENT.

The active controlling speed is highlighted by reverse video characters (on lines 2L or 3L).

Path descents are altitude constrained and require manual speed control. If a lower MCP altitude has been selected, then V NAV descent is automatically initiated at T/D. The computed profile terminates at the end-of-descent (E/D) altitude/waypoint. Only if a mandatory "at" altitude restriction is specified at E/D can a path be computed.

Amsterdam, Schiphol to London Heathrow in the Greatest Airliners: The 737-400 A short introduction to flying with the FMC by Elmar Calbo, August 11 2001, The Netherlands

(For use the FMC version 1.2.0 or above)

INTRODUCTION The purpose of this introductory flight is to show you one way of flying the DF737. With the complexity of this airplane, there are many ways to accomplish the same goal, which in our case is performing a take-off from runway 19L at Amsterdam Schiphol and a landing at runway 27L at London Heathrow. We will use a standard departure and arrival and follow a direct route between them. We will not look at standard checklists, which are compulsory for a good reason for real pilots, but just do some quick checks prior to take-off to ensure we have an aircraft that can fly us safely to our destination, nor will we do a taxi. By using the PMCG, we can be ready to fly very fast, as you will see. I am by no means a pilot in real life nor a flightsim expert, I just enjoy flying the DF737 from Schiphol to London safely, having a great flight and experience too thanks to the good folks of both DreamFleet2000 and Flight1, who brought us the Greatest Airliners: The 737-400 package. Let’s move on to getting this flight to depart on time! SETUP With FS2000 running, jump to the 19L runway at Schiphol. If you want you can set the time, date and some clouds, but do not add any winds. We want to make sure that Mother Nature does not interfere with our flying skills until we have fully mastered the flight. Once you are happy with the environment and aligned on the runway select

your favourite DF737 from the Aircraft menu. For this introductory flight we need an aircraft with all systems and engines running. Get rid off the yoke, open the overhead panel and confirm that the green Taxi light is illuminated on the PMCG (top left) panel. If it is not, that means you are running the DF737 in another mode, which we do not want at this time, so if the green Taxi light is off, select it first, then select another aircraft (not another DF737, but a LearJet45 for example) and then switch back to the DF737. At the moment of writing this, there is a small bug around which can cause both the EHSI and EADI to be blank at times. If that is the case, the most likely reason is a problem with the electrics. If the EHSI/EADI are blank, open the overhead panel and check the electrical panel on the lower left side. If all the bus lights are illuminated (4 lights will have yellow characters, and you will notice Low Pressure lights illuminated all over the other panels as well) we have found the problem and can fix it by re-connecting the busses by clicking the switches for Gen1, ApuGen and Gen2. This will most likely fix the EHSI/EADI. The 4 lights that were illuminated should be off. Now we will load up our fuel for the flight, from the FS2000 Aircraft menu, select Fuel and use 50% for the center tank, and 30% in each wing tank, we do not need full tanks for this flight, and keeping them on 100% will have us arriving a very heavy bird. Please note that loading the fuel as described above will not cause any problems in this simulator, but in real life we would fill our wing tanks to full and add the additional amount of fuel needed for the flight to the center tank.

Okay, now we are sure our aircraft was started in Taxi mode, the fuel was set and we are on Runway 19L at Schiphol, let’s close the overhead panel and move on to the next bit. SETTING UP THE FMC The Flight Management Computer included in the DF737 is a lot of help while flying. Not only is it able to steer the aircraft along a preset route, using a VNAV and LNAV mode, it will help us setting V1/VR speeds and determine the correct landing speed as well. There is actually a lot more about it, but you will find out quick enough when using it. On this flight, I could say we will be using the FMC to it’s fullest, but once you understand what it is capable off you will call me crazy for saying that and have it make coffee for you. We will not utilize the FIX or HOLD functions for example. Start the FMC by pressing the hotspot on the lower right of the main panel. If you don’t know where that hotspot is, it looks just like a FMC. Once the FMC is started we can take it in and out off view by either pressing the hotspot again or using the Tab key. Do not close the FMC through it’s own right click menu as that will not bring it out of view but terminate it completely! A LSK is a Line Select Key, and the FMC has a row of 6 LSK’s on the left and the same on the right. Input to the FMC can be done through the FMC’s keypad or by pressing the Scroll Lock key, which will map your own keyboard to the FMC. If you choose for the Scroll Lock method, remember to disengage it after you are done! When your keyboard is mapped to the FMC, the green light in the top left corner will illuminate. Whatever input method you use, your input will be taken to the scratchpad first, and can than be entered into the FMC by using the LSK’s as we will see later on.

The FMC starts on the IDENT page, which holds nothing we want to change. Click the right LSK6 to take us to the POS INIT page. We will need to let the FMC know where we are, so enter EHAM (which is the ICAO code for Schiphol) into the scratchpad and select it into the FMC by pressing left LSK2 (Ref Airport). As you will see, the FMC will pick up the position. Click the right LSK6 to go to the ROUTE page. This is where we will start setting our entire route, from the departing to the arrival runway.


5-3
Enter EHAM into the scratchpad and select

into left LSK1 to set our origin. Enter EGLL (the ICAO code for London Heathrow) into the scratchpad and select into right LSK1 for our destination.

Click the right LSK6 to go to the Route page. We have set our departing runway, and will now have to do the same for our arrival. Click on DepArr for the Dep/Arr Index page.
Click the left LSK3 to take us to the EHAM Departures page. On this page we will see all the available runways, so we need to find our runway, which is 19L. This can be found on the second page, so click the Next Page button to display that page. You will see 19L listed here in the first position.
Click on the right LSK2 to go to the EGLL Arrivals. As you will see, the navigational database supplied with the DF737 holds both runways and standard arrivals for London Heathrow. We will use a standard arrival, and later on we will manually program a standard departure route as well.
Click the right LSK1 to select runway 19L. Once done, it will show <SEL> in front of 19L.

Click on left LSK5 to select the BIG3C arrival. Click on the right LSK5 to select runway 27L. Click on left LSK2 to select DVR for our

Transition. This is not shown in the picture

above (this is where we will have our route pick up the standard arrival) The FMC will create a Runway Extension point at the distance set in right LSK3, which is set at 12 nautical miles and is fine for us. You can shorten this distance a bit or if you would like a little more time to stabilize for the approach, lengthen it. The default 12nm is good though, so we will not change it. Click on right LSK6 to go back to the Route page. As you can see, the Route now uses 2 pages. It is now set to fly direct to waypoint DVR (which is Dover) and then use the BIG3C route to BIG. Press the Next Page button to go to page 2. Here we see the next hop, which is again the BIG3C route, this time to RX-27 (our fix for the runway) and then direct to Runway 27L. The waypoint MA-27 below the RW27L is one we hopefully will not be flying to, as that is our missed approach point.

On the legs page you will see that the first waypoint currently in our route is DVR. We will add a few here We will use a standard Valko departure, and have to set the waypoints for it on the Legs page manually, so press the Legs button first. On the legs page you will see that the first waypoint currently in our route is DVR. We will add a few here. Enter EH029 into the scratchpad and click left LSK1. This will add the waypoint EH029 to our route, above the waypoint previously at LSK1. Enter EH009 into the scratchpad and click left LSK2. Enter VALKO into the scratchpad and click left LSK3.
Okay, we are going to use a standard departure (SID) as well, and even though the navigational database for the DF737 does have them for EHAM, we will do those manually to familiarize ourselves with the procedure of adding waypoints.

If all went well, our route is now EH029 – EH009 – VALKO – DVR – LYD – TIGER – BIG12 – BIG – RX-27L – RW27L – MA27 (Again, use the Next Page and Previous Page buttons to walk through the pages) Go to the PERF INIT page by clicking right LSK6

FMC cannot and operates in lbs mode only. Dreamfleet has stated this will be updated. Now, our cruising altitude. For a flight as short as this one, we will use a cruise altitude of 15000ft. Enter 15000 into the scratchpad and select into right LSK1. In Europe, which is where our flight will be taking place, the transition altitude is 6000ft instead of the 18000ft used in the United States. Enter 6000 into the scratchpad and select into right LSK5. If the FMC requires information not yet inputted to perform, it will show boxes, if the information is optional, it displays ---. As you can see, the other items on the Perf Init page are optional, they all show ---‘s and we will not input anything there on this flight. The Exec button has illuminated indicating we need to push that to activate our input, so click the Exec button. Click right LSK6 to go to the Takeoff page On the TAKEOFF PAGE will have to input the current temperature of our departure airport in Celsius.

We will now finalize pre-flighting the FMC. The FMC will use the data we now enter to calculate the altitudes and speeds at our waypoints. You might have noticed that some were already filled in on the legs page and others were not. Let the FMC take care of those. On the PERF INIT page click left LSK1, this will automatically check the Zero Fuel Weight of our aircraft, add the fuel and calculate our Gross Weight. This feature is not found on real aircrafts, but put in the DF737 FMC for our convenience, and actually, it is a feature I much appreciate. Enter 5 into the scratchpad and click left LSK4 This sets our reserve fuel at 5000lbs. Although on our panel we can switch from lbs to kgs, the

prompt at right LSK6. Click right LSK6 and click the Exec button to activate our changes.

As you can see, the FMC has now calculated the V1, VR and V2 speed. We have to transfer those to our EADI and clicking the corresponding LSK’s does this. Click right LSK1, 2 and 3 and notice the EADI displays V1 137. Almost done with the FMC now. As you can see our Pre-Flt Status still displays something to do at the Route page. Click right LSK4 to go to the route page

Notice that the page now holds an ACTIVATE

You can check the route we will follow by going to the Legs page by clicking the Legs button. Notice that the FMC has calculated speeds and altitudes for our waypoints.

If you want to save the flight plan we just created, click right LSK3 on the ROUTE pages to go to the Flt Plan Import/Export page, enter a filename in the scratchpad and select into right LSK3. Our FMC pre-flight is now complete, so we can close the FMC by pressing the tab key or hotspot. If you used the Scroll Lock method to map your keyboard to the FMC, make sure you turn this off now and confirm the green light in the upper left corner of the FMC goes out! Here is some info about our route before we go to the next bit. We will use the MCP altitude to hold the climb at 6000ft until we pass waypoint VALKO and then allow a climb to 15000ft, which will be our cruising altitude. Around waypoint LYD we will set the MCP altitude to 3400ft which will allow the FMC to start descending somewhere between waypoint LYD and TIGER as per it’s scheduled descend as seen on the
DreamFleet 2000

5-7
legs page. If we would not reset our altitude, the

MCP would restrict the FMC from descending. It is very important that you change altitudes on the MCP but do not activate them by using Lvl Chg or V/S modes! Let the FMC do the work on this flight. As you will see, even though the FMC has set much higher altitudes at waypoint along our route, we can and will use the MCP to limit it on this flight. Somewhere around waypoint BIG12 we will take over the vertical path from the FMC and at waypoint BIG we will thank it for it’s services and take care off the horizontal profile as well. SETTING UP THE AIRCRAFT We are now ready to set-up the aircraft and the first thing we do is open up the center radio console. First change both nav radios to Auto by clicking their illuminated buttons (which now show Man). Notice that the caption changes to Auto and the displayed manual frequencies are crossed out. We will be arriving at London Heathrow runway27L and use an ILS approach, which will guide our aircraft to the runway both vertically and horizontally. We will need at least one of our navradio’s tuned to the ILS27L frequency, and if you would go and try an autoland, we will need to tune both of them to that frequency. It doesn’t hurt to tune both (even though we will not autoland in this flight), so change both manual frequencies to 109.50. Leave the radios in Auto mode though. While we are at the center console, we will change the display mode on the EHSI to Map and the range to 20nm. Notice that the EHSI will now display our route. Close the center console and open the overhead.

Turn on the landing lights, close the overhead and open the gear panel. On the gearpanel we will set the autobrakes to RTO (Rejected Take Off). Notice the Autobrk Disarm light go on and off. If we decide to abandon the takeoff on the runway, closing the throttles to idle will trigger the autobrakes. On the MCP select the F/D to on and the A/T to arm. An FD notice will show on the FMA (Flight Mode Annunciator) on the EADI and a green light will illuminate next to the A/T switch. Set the IAS/MACH to 250kts. Set the heading to 186. This is the heading for the runway. It is good practice to set the MCP heading to follow the FMC route. This is not necessary for correct operation of the FMC, but just good practice in case the FMC goes AWOL and we want to use Hdg Sel mode. Set the altitude to 6000ft. This is the restricted altitude until we reach waypoint Valko. By setting this altitude, it will prevent the FMC from climbing any higher until we dial in a higher altitude, which will then allow it to climb again. Select Autopilot A. Our MCP is now correctly set up. Please note that we have not bothered with the course button. Select flaps 5 and confirm this on the gear panel, there will be a co-pilot callout as well. TAKEOFF Well, it looks like we are ready to go flying. o Smoothly push the throttles forward and

allow the engines to stabilize at 40% N1. o Release the parking brakes. o Hit the TOGA switch and notice that the

EADI displays TOGA and the F/D crosshair comes on.


5-8
o At VR smoothly pull back on the yoke to start

rotation and once clear from the runway increase your attitude to around 15 degrees.

o Confirm positive rate, i.e. the altimeter running up, and select Gear Up.

o At or above 400ft radio altitude (as displayed on the EADI) select LNAV and VNAV, they will both illuminate. The FMC will now take over flying the airplane and you will see the mode changes on the FMA (check the EADI display) and notice the FMC following the planned course.

o Select Autobrakes to off and close the gear panel.

o Select Flaps 2 at 160kts o Select Flaps 1 at 200kts o Select Flaps up at 220kts Notice that our climb will stop at 6000ft and CRZ mode will be active instead of TO or CLB and we will cruise at 250kts which is set in the FMC as a restriction below 10000ft. This is default and can be changed, but we did not do that. If you did not set the heading on the MCP to our current one, do so now. Try to make a habit out of setting the heading on the MCP to the current one every time the FMC makes a turn. Change the range setting for the EHSI to 40nm. Once we pass Valko, we will set the altitude on the FMC to 15000ft. As soon as you do that, you will notice that the FMC commands a climb, CLB mode will show and we will start climbing to 15000ft with N1 and VNAV SPEED showing on the FMA. Past Valko, the FMC will again command a turn, so we will set the MCP heading to our current one shortly after the turn. Change the range setting for the EHSI to 80nm. Passing 10000ft we turn off the landing lights on the overhead. It is collision avoidance practice to have the landing lights on below 10000ft and off above that level.

The aircraft will continue to climb and level off at 15000ft, change to CRZ mode, and our speed should be around 311kts with FMC SPD and VNAV PTH showing on the FMA. You will notice an Altitude Alert shortly before reaching our set cruise level, and the FMA displaying it’s new modes in boxes indicating it’s changing to that mode. It will take us a little while to get to waypoint DVR, which is where our actions are required again, so if you want to enjoy the view, now is the time! If your outside views still show the default aircraft, remember that DreamFleet has lots of free liveries available at their website, so you could fly for almost any carrier you so desire. At any time during our flight we can open up the FMC and use the Legs and Prog pages to see our progress, calculated speeds and altitudes. At waypoint DVR, set the EHSI range to 40nm. At our current speed it will take approx. 3 minutes to reach waypoint LYD, which is where we will allow the FMC to descend along it’s calculated path. At waypoint LYD we reset the altitude on the MCP to 3400ft and you will notice that the FMC commands a descent shortly after that. Follow the FMC commanded turns on your MCP heading. During our descent, the speed will start to drop as well. The FMC has calculated a speed of 220kts at RX-27L. We will however take over well before that and turn to the runway at a much lower speed, in our case around 160kts. At waypoint BIG12 we will select V/S mode on the MCP and set the vertical speed so the green arc on the EHSI will be just short of the RX-27L waypoint and set a speed of 220kts on the MCP. Set the EHSI range to 20nm. Notice that changing the V/S mode has also made the



5-9
IAS/MACH active. Remember to follow the
heading on the MCP! During this part of the flight, you will be setting the flaps accordingly to speed, to arrive at Flaps 15/160kts at waypoint RX-27L. Make sure the predicated point where we will be at 3400ft stays just short of waypoint RX-27L (indicated by the green arc on the EHSI), so adjust the vertical speed if necessary during this entire part of the flight. Just before waypoint BIG, we set a speed of 180kts. We will then set our heading on the MCP so it will take us to RX-27L (check the magenta dashed line on the EHSI) and click HDG SEL. At this point, we are not using the FMC anymore, as both VNAV and LNAV mode are inactive. Go to the center radio panel and select Nav1 to manual, at frequency 109.50. That is the frequency for the ILS system on Runway 27L at London Heathrow. We have already set the frequency prior to our take-off, so if all is well, you will just have to set the nav1 radio to manual. When we are 5 miles out of waypoint RX-27L we will set the speed to 160kts on the MCP, and select flaps 15 when reaching that speed. When the ILS comes active, it will show the horizontal and vertical indicators in magenta on the EADI. When the horizontal and vertical ILS indicators are active, hit the APP button on the MCP. Notice the EADI showing G/S and VOR/LOC in white. Lower the gear, select autobrakes 2 and arm the speed brakes. When they are both captured (G/S and VOR/LOC modes active and green), the aircraft will need a little time to fully stabilize. Once it is stable, both magenta indicators on the EHSI should be around dead center and we can set

our final speed and flaps. Normally it will be stable well before we reach 2000ft. Set speed on the MCP to be 150kts and select flaps 25 once the aircraft is stable on the ILS approach. We will allow the A/P to follow the glideslope to the runway, but conduct a manual landing, so we need to turn off both the A/T and A/P at a certain point. o -At 400ft radio altitude (check the EHSI) turn

off the A/T and A/P. o Keep the vertical speed at around 700fpm. o At 50ft radio altitude, close the throttles to

idle and flare. o On touchdown, engage reverse thrust,

deploy speed brakes and brake. o At around 60kts groundspeed, turn off the

reverse thrust, continue to brake and slow down the aircraft to below 30kts, turn off the autobrakes and leave the runway at the earliest possible exit, taxiing at maximum 25kts.

Welcome to London Heathrow, I hope you enjoyed this short flight from Schiphol to London Heathrow and learned some more about pre-flighting and using the FMC. If you would like to have the maps for both Amsterdam Schiphol and London Heathrow, you will be glad to know that both are available for free on the Internet, and very extensive, covering everything from the airport layout to SIDs and STARs. Amsterdam Schiphol: http://www.globalflightdeck.com/approach.htm London Heathrow: http://www.ais.org.uk/uk_aip/pdf/ad/aipad2.pdf I would like to thank the team that built the DF737 for an outstanding product.
