Tupolev Tu-154 in X-plane 11

Tu-154 Youtube series

This page is dedicated to the most complex, unconventional, and most difficult to operate aeroplane in X-plane 11 to date, the Tu-154M by Felis.

This is a step-by-step walkthrough for a normal flight. We will use conventional navigation, Orthodromic navigation with Doppler radar and operate the KLN90 GPS as a backup.

Because the real Tu-154 is has a crew of 4, and we are going to fly on our own, expect a high workload at times. Maximum use of the autopilot, good flight planning and a good understanding of the aircraft systems are key elements for a successful flight.

Although I encourage to fly this aircraft in the Russian setting so you can enjoy the full ambiance of an airliner of the Soviet Union, for the sake of this tutorial I will fly it in the English layout.


Complete Tu-154 for X-plane series on youtube


  • X-plane 10 or 11. This tutorial is written with version: X-plane 11.05 (Payware)
  • Tu-154M addon by Felis (Payware)
  • XNVU calculator by Vantskruv
  • Mastery of the Russian language
    • Nope! this model now comes with optional English cockpit layout!


  • Up to data X-plane navigation database, helpful but not essential. (Payware)
  • Better pushback as alternative of using reverse thrust to back off the gate

Before starting X-plane

Seriously! don’t start x-plane yet! and if you just did, close it… unless of course, you wish to add every waypoint in the GPS manually! The KLN90B only reads the flight plan files at X-plane start up.

Also, before starting the sim I recommend to download and install custom scenery for the airports you plan to use. Then connect and calibrate the joysticks and grab that bottle of водка from the fridge 😉

Prepare a flight plan:

To generate a flight plan, I use Skyvector because it is easy to use, and free of charge.

01 Skyvector

Keep in mind that the Tu-154 is not Prnav approved, and every waypoint with a turn increases the workload significantly. So try to plan a route with long legs and overflying conventional aids (VOR or NDB) where possible.

Today we will be flying the route from Vilnius to Plovdiv.


Open the XNVU.exe utility.

If this is the first time you use this utility, it is necessary to adjust some settings. In the top bar, go to Settings and setup the folders for XNVU to find its data from.


Close the settings page when everything is setup.

Copy and paste the route string into the ‘insert route’ field at the bottom, include the airport codes at the start and end of the route, remove any sid and star’s. then press ‘Insert before’


03 XNVU route

If a waypoint is missing fro mthe XNVU database:..
.. then you can  manually add a waypoint. On the top, select Settings/XNVU Library/Create new…
The fill in the identifier, name and country code, the LAT/Long need to be converted from degrees/minutes/seconds, to degrees/decimal.
For example, 531412N0063838E, convert seconds to minutes and minutes to decimal:
((12/60)/60)+(14/60)+53 = 53.2366667 

Longitude ((38/60)/60)+(38/60)+006 = 6.64388889

Now that the entire route is in XNVU, we need to modify it to suit the 1990’s navigation equipment. For the KLN90b GPS, we can only have a maximum of 30 waypoints. for the NVU, we need to remove all waypoints that are not a turn.

So if we compare the route in skyvector with the route in XNVU, we can see that DUKAT is our first waypoint, then NOPKA and then OSMUS, however NOPKA in not a turn point, so we won’t need it. Select waypoint and click ‘Delete waypoint’.

Do the same for BUSIN, GANVI and ROMLU, but leave PNK in! do this for the rest of the route.

Now we are going to add correction beacons to the route. You can do this manually by right clicking on a waypoint, or chose Utils/Autogenerate correction beacons.

04 Correction beacons

Once finished, click on the top bar Export/Print “Print…” or “Print to PDF…” to generate an NVU navlog.

Then click “Export to KLN90B…” and call the file 1.fms (1-25 but not 0)

Now you can start X-plane 11. Ensure the option of start with engines running is OFF and the flight is started at the Gate or ramp.

Load sheet and fuel

  • Aircraft load utility (left side, MENU SERV LOAD)
    • Set ‘Enroute dist, km’
      • So take the distance in NM
      • Add headwind, (for example, 50 knots headwind for 2 hours, add 100NM)
      • Add up and then multiply to 1.852 to convert NM to KM
      • In my example ( 850Nm + 100 Nm for headwind ) * ~1800KM
    • Set ‘Alternate dist, km’ the same way.
    • Click load fuel
    • Add payload, and ballast to remove reds/orange fields
    • and “load fast” or “load slowly”

Note: Load slowly will add a fuel truck animation but does not work when the APU is on!

Orthodromic Navigation

After a steep learning curve, it is not extremely hard to navigate using the NVU, however it requires almost constant attention of the pilot so it becomes a distraction from other tasks. Also a simple wrong input can ruin the navigation completely so you have to work extremely accurate and double check your numbers every time!

The Tu154 is designed to operate close to the north pole, where a magnetic compass is no longer reliable. Instead, the magnetic variation of the departure point is held in the gyro-units, until a change-over point somewhere along the route, where the gyros are transferred to the variation of the arrival airport.

Therefore the nav-log has a few fields that require some more explanation.

  • All numbers in red are used before the transfer of the gyros.
  • Numbers in blue are used there after
  • For basic navigation:
    • OZMPUv is the Orthodromic course based on the departure airport
    • OZMPUp is the Orthodromic course based on the arrival airport
    • S is the leg distance in KM
  • For correcting the gyro compasses with the KM-5 units
    • Pv and Pp are the difference between the local and the orthodromic variation
  • For automatic correction with the RSBN beacons
    • RSBN is perhaps easiest explained as the Russian equivalent of VOR/DME
    • Sm and Zm are the location of the RSBN beacon relative to the next waypoint
    • Map Angle is the angle with reference to the RSBN beacon, required for corrections

Before switching to NVU navigation, we have to ensure that the navigation computer is setup correctly. After the initial input from the navlog, there are several ways to do this.

  • Updates the position using an RSBN beacon. However this is quite labor intensive, and only available in the former Soviet Union.
  • Fly a departure with VOR/DME ending at the first NVU waypoint. When passing the fix, manually switch waypoint or switch the NVU on
  • Overfly an NDB enroot en manually switch the NVU on.

NVU automatic navigation

  • Set NVU/GPS switch to NVU (centre main panel)
  • Doppler
    • Set NAV to NVU BY DOPP on the overhead panel
    • Set DOPPLER in GROUND or SEA mode (for overflying land or water)
  • Select NVU on the autopilot panel for automatic navigation
  • Monitor distance to next waypoint on NVU calculator
    • Set TURN selector to 5km. (10 or more for very sharp turns at high speed)
    • 5km before reaching the next waypoint it will switch from waypoint I to II and vice versa.
    • Set the next course (to waypoint 3) in CAS I
    • Ensure selector is in Sp and change pre-select distance for waypoint 3 (negative value!)
  • Repeat the last step pretty much until you can start the approach with conventional radio navigation.

RSBN correction

  • Ensure you have sufficient time on this leg, I recommend at least 100km remaining to the next turn
  • Set Sm and Zm value of the current leg in the NVU (select Sb and Zb if the language is set to English)
  • Set the map angle on the MAP ANGLE DEGREES dial on the forward pedestal
  • Set RSBN channel on overhead panel and confirm the beacon is in range (RSBN indicator is moving)
  • Set autopilot PREPARE NAV mode OFF
  • On the NVU computer, set CORR on, and after the correction is made, switch it off again
  • Fly the aircraft back on course using the turn knob, when the Z is 0km, (and the needle is in the centre) engage PREPARE NAV and NVU mode again

Manual position update Z km using DME

  • When flying directly towards a DME station, and the distance is more than 100km, you can adjust the Z value on the NVU to correct distance to the station

Manual position update S km using VOR or NDB

  • switch CALC mode off
  • Manually fly the aircraft to the beacon (on autopilot use heading or turn mode)
  • Setup the NVU for the next leg according to the navlog.
  • When overhead the beacon, reengage CALC mode

Switching magnetic reference using the fork

This procedure should be done at any point in the orthodromic navigation part of the cruise.

  • Set autopilot PREPARE NAV mode OFF
  • Note the Fork, deg. value on the top of the nav-log
  • On the overhead panel, set CORRECTION to REF and DG
  • Manipulate the COURSE SET switch
    • Adjust the reference gyro, see the change at main gyro instrument.
    • The small arrow should change by the value of the fork
    • And after the correction, point at the new navigation course in the plog (blue)
  • Set the CORRECTION to MAIN
    • Repeat for the main gyro
  • Adjust the NVU computer
    • Set blue values for course in the CAS windows (both active and standby course)
    • Select Z and reduce Z value to zero

Correcting gyros in flight using KM-5 units

  • Set autopilot PREPARE NAV mode OFF
  • Note the Pv or PP value (before or after transfer of the gyros)
  • Set the KM-5 units to this value
  • On the overhead panel, press and hold ADJUST MENT
    • In DG mode, repeat for both CORRECTION MAIN and REF
