Preface

 

Welcome.

The Joint Strike Fighter (JSF) Program was introduced to provide an aircraft suitable for use by all forces involved in combat aviation. The premise of which, was to utilise a common airframe and power plant platform for ease of production, serviceability and cost effectiveness.

Of the two designs submitted for the program, the Lockheed Martin X-35 was selected for production as the F-35. This design has three variants:

 

The F-35A. To be used by the USAF to replace the F-16.

 

The F-35B. To be used by the US Marines and by the RAF and RN Fleet Air Arm to replace the AV8 / Harrier.

 

The F-35C. To be used by the US Navy to replace the F-18.

 

Of the three variants, the F-35B is the most sophisticated, being capable of  Short Take Off and Vertical Landing (STOVL).

 

This manual is a guide to the systems and controls used in the X-35 Aircraft model, designed for Microsoft’s Flight Simulator 2002/2004.

All three models will be covered in this manual as they share common features.

Essentials

 

Keyboard Assignments.

This manual will refer to the FS default key assignments used for flight and engine control. But before the models should be flown in FS, there are a few Key assignments that need to be setup to be certain of correct operation of some of the extra features in the models.

 

There are three assignments to be made. These are:

 

Tailhook Up/Down. This should be “Shift + T”

 

Water Rudder Up/Down. This should be “Shift + W”

 

Wing Fold/Unfold. This should be “Shift + F”

 

Gauges.

To make it easier to uninstall the aircraft, all the gauge & CAB files used by the X-35 (A, B & C) are placed in a separate folder called “X-35”. This folder must be inside the Gauges folder. Here is an example of how the tree should look.

 

 

 

 

Also make sure that the “Gaugesound.Dll” file is in the main FS2002 folder or the panels may cause FS to crash.

 


 

 

 

 

 

 

X-35A/C

 

Overview

 

To make creating these models easy, there are very few differences between them. I suspect this is not the case for the real aircraft as each has a specific role to play. But converting the A to the C was less time consuming than creating the C from scratch. The main differences of the C over the A (in my models) are:

 

Extended wings incorporating added Ailerons (the A and B just use Elevons).

 

            Extended Elevator surfaces

 

            Folding wing sections

 

            Tail hook

 


Cockpit Layout

 

X-35A

 

X-35C

As can be seen, the only difference between these cockpits are the extra indicators at the top left of the C panel. These are the Wing fold and Tail hook indicators / controls. All other indicators and controls are the same.

These controls can be operated with the mouse by left clicking on the required indicator.

 

Common indicators / controls to all 3 Variants

 

I’m going to be very lazy and assume that if you downloaded this / these aircraft that you at least have a rudimentary knowledge on how to fly (in FS at least) and are there fore familiar with the basic displays e.g. ADI, VSI Altitude and Speed, and know them when you see them!

What this manual is for is to explain the extra, specific and special displays / controls, used in these models.

 

 

  1. HUD controls. 1st Button operates ILS (See MFD Controls). Next 5 are brightness. Last button is Pitch Ladder on/off.
  2. Light status. Beacon, Strobe, Navigation, Landing and Panel.
  3. Outside Temp, Mini GPS and Wind direction / speed.
  4. Wheel Brake Hydraulic Pressure. Top is left, bottom is right. These are not calibrated in any way they just show when the relevant brake is applied. Parking brakes will show full pressure where normal brakes show around 75%.
  5. Undercarriage Lever (currently down). This lever can be operated with the mouse.

 

A, B, C. These are MFD switches. The green boxes show the operational area of each switch. A, switches the left MFD to Engine management mode. B, switches the Left MFD to Radar mode. C, switches the Right MFD to GPS mode.

 

 

D. Toggles VOR 2 needle.

E. Toggles ADF needle.

F. Altimeter barometer adjustment (hidden knob). Left side of the screw

    head is minus, Right side is Plus.

 

MFD Controls

 

ILS.

 

If the runway you’re landing at has ILS, you can use this as a guide for your descent. Tune the NAV1 radio to the runways Localizer / Glide slope frequency and click on button 1 of the HUD buttons or press “Shift + 2” to bring up the ILS in the HUD. The Above image shows the correct position on the glide slope and localizer.

 


This shows us as too high and too far left of the runway,

 

this shows us as being too low and too far right of the runway.

 

 

 

 

Engine Management and Flight systems (A and C Variants)

 

 

  1. MFD toggle switch area.
  2. Throttle position display.
  3. N1. Low pressure compressor speed (percentage RPM).
  4. N2. High pressure compressor speed (percentage RPM).
  5. EGT. Exhaust Gas Temperature (degrees C x 100).
  6. Fuel Flow. (Pounds per hour x 100).
  7. Percentage of fuel remaining. (Left Aux, Left Main, Right Main, Right Aux).
  8. Spoiler (Airbrake) position (DN is fully deployed).
  9. Flap position (DN is full flaps).
  10.  Graphical indicator of Flaps, Spoilers, Afterburner and Landing gear (currently down).

Global Positioning System (GPS)

 

 

This is the standard GPS moving map supplied by Microsoft in FS2002 with the buttons coloured in!

Instructions for use are part of FS2002.

 

  1. MFD toggle switch area.

 

The standard GPS button on the main cockpit panel, opens this as a larger display for easier viewing.

  5. (Once Highlighted) Contacts Vertical speed, Altitude (auto toggles).
  6. (Once Highlighted) Range to contact.
  7. (Once Highlighted) Contact ATC no.
  8. (Once Highlighted) Contacts speed.

 

The HUD (but not the ILS) forms a part of the package this display is from and information on a highlighted contact is also displayed as a bottom line on the HUD showing Contact heading, Range to Contact and bearing to Contact.

There are four modes to this RADAR.

  1. Off. Blank display
  2. 360 degree. Initial start up mode (see above image).
  3. Forward Horizontal Mode (see Radar image 1).
  4. Forward Vertical mode (see Radar image 2).

 

There are four ranges. Start up range is the maximum 40nm. Reducing to 30, 20 and finally 10nm.

X-35B STOVL

 

Overview

 

About 1999, I got my copy of FS98 and took great delight in downloading aircraft and panels and making subtle changes to the look and feel of them. Then I chanced across a web site dedicated to the JSF project (before the winner was announced) where I first saw the design for the X-35B. Being a huge fan of the Harrier and the technology behind the first single engine VTOL aircraft, I fell instantly in love with what will be - the Harriers replacement. So much so, that I wanted one for my FS98. So I scoured the web looking for a plane to download and finally found one on Simviation. Called “Cyclone”, it was in a dark grey livery with Royal Navy markings. And while it was a fine effort by its creator Giuseppe Chiacchietta, it was only a conventional take off and landing model. However, on the same web site was a model of the GR7 Harrier (which of course I also downloaded) by Jim Atkins. Which featured (above all its other fine qualities), an Air file giving the aircraft a VSTOL capability. Wheels started to turn in my head. And it wasn’t long before I had a VSTOL JSF (X-35) “Cyclone”, flying around on my PC in FS98. But I wasn’t satisfied with that. I wanted something more. And the only way I was going to get it was to make it my self. So armed with my credit card, I bought FSDS v1 with Aircraft Animator. And set about designing my own version of the X-35B. After months of work and trial & error, I finally achieved an aircraft that I felt proud enough of to up load to Simviation. Using Jim Atkins’ Air file (to whom I gave full acknowledgement) but only having plain grey textures (I wasn’t that good at texturing), what it lacked in appearance, it made up for in moving parts. All the doors were animated (to the best of my ability given the limitations of AA), as were the compressor and lift fans and by no means least, the jet nozzle (by far the most complicated bit of animation in the whole model).

 

With FS2000 came a slight revamp but not enough to warrant an upload.

 

And then came FS2002.

 

 

With its ability to use Key frame animation and parent / child part association, I decided to make some major changes to the X-35B. Not least to add some basic textures that others could modify (and hopefully repost) but also a virtual cockpit. And so it was that I finally reposted the new improved X-35B, using the latest Harrier Air file from Jim Atkins and other additions from other people (to whom I also gave full acknowledgement as one should).

After a couple of months and a few e-mails asking about possible texture updates (not least one from someone working at Lockheed Martin!!!), I received a mail from Claudio Mussner, asking about textures but also offering me an airfile  and special landing gauge specifically designed for the X-35. This mail was to spark off a series of communications culminating in a complete change in the X-35B, including modification to the fuselage, updated animations, complete texturing of the model, additional detailing, improved flight model (courtesy of Claudio Mussner), new 2D cockpit panel and 3D Virtual Cockpit, the list seems endless. It also contributed to the creation of the other two variant models and the need to package the whole thing properly (hence this manual).

 

Although I will be making all the relevant acknowledgements at the end of this document, I would like to give a very special thank you to Claudio.

Without your encouragement and input (not least with the airfiles), these aircraft models would not have reached the level that they have.

Thank you.    

 

X-35B STOVL Systems Overview

 

Since FS has no vertical take off ability for fixed wing aircraft (not changed in FS2004 unfortunately), it is only possible to effect a virtual vertical take off / landing system. Basically, the flaps are used to give extreme levels of lift for very low forward momentum. But to maintain a normal flight characteristic using flaps for conventional takeoff and landing, the number of flap positions is increased. Giving the first half normal flap dynamics, and the second half the STOVL dynamics, allowing for a gradual transition from normal flight to “hover”. In Our model, the first STOVL position opens the lift fan doors and engages the fan. Subsequent positions, increase lift while decreasing the forward speed requirement, until virtual hovering is reached (approx 65% throttle for 6kts forward speed).

Note. Where used, wind speed and direction has an effect on the aircraft (in the right conditions, you can actually hover or even go backwards).

 

The rudder can be used in STOVL mode to yaw the aircraft left and right. Used sparingly, this will turn the aircraft without rolling. However, if applied continuously or excessively, this will induce roll which causes forward motion to be translated to a sideways motion. While this makes for great carrier landings, it must be noted, if the forward speed reduces to zero, FS has no figure to base lift on. This will cause the aircraft to pitch nose up and over, which tends to be unrecoverable at low altitudes (which is what you’re normally at when taking off and landing).


Cockpit Layout

 

 

At first glance, the cockpit doesn’t look any different to the X-35C. However, the indicators in the top left of the panel, are different. Gone are the wing fold and tail hook lights, to be replaced with Lift Fan & Lift Boost lights. The Lift Fan light is fairly obvious as to its purpose, lighting up as it does when the central lift fan is engaged for vertical flight. The Lift Boost system offers the pilot the ability to engage extra thrust above that of full throttle should it be required. And can be engaged in two ways:

 

  1. By engaging the Afterburner (essentially what gives the extra power).
  2. By pressing the wheel brake button (trigger / button 1 on the joystick or “.” (period)). This is the recommended option.

As the operation of the brakes is a momentary one i.e. will only work for the duration the button is held down / trigger pressed, this is the best option for the use of the boost system to facilitate short bursts if needed.

 


MFD Control

 

STOVL Systems.

 

As you can see, this is essentially the Engine Management MFD and is accessed using the same toggle switch. But as you can also see, there is more to this version than the A & C versions.

 

  1. Throttle display. When the STOVL systems are engaged, the display changes from all green to the half green / orange you see here. If you allow the throttle to fall below 50%, all vertical lift will cease and the aircraft will begin to fall out of the sky at an incremental rate.
  2.  
  3.  
  4.  
  5.  
  6. The same as the A & C.
  7. Height above ground level (not necessarily altitude above sea level), degree of aircraft bank (- is banking to the left), degree of aircraft pitch (- is nose down)
  8. Lift fan door indicator
  9. Nozzle position indicator. UP is 0 degrees (horizontal), DN is 90 degrees down (vertical). Currently showing 60 degrees.
  10. Graphical representation of systems. Upper picture shows Pitch, Lift fan and Nozzle operation. Lower picture shows Bank, Afterburner and Flap/Spoiler/Gear systems.

 

 

 

Virtual Cockpit

 

In FS2002, the virtual cockpit is a non interactive environment, save for viewpoint changes and aircraft animation e.g. moving throttle and joystick. In FS2004 you can interact with the displays and gauges as in the 2D panel. Watch this space!

 


Extra Features

 

If you have read through the “Essentials Section”, then you will already know what to press to make the wings fold and the tail hook go up and down on the C variant. But you have probably been wondering what the water rudder is for.

Well, on all the variations, the water rudder control is used to implement the animation of the refuel nozzle. In the 2D panel, you will see a 2D operation. But, in the virtual cockpit and external views, you can see the actual nozzle operation. This is just a bit of eye candy as there is no in-flight refuelling in FS2002. This is also operated by left clicking on the switch above the Gear Lever on the main 2D panel

 

The main panel was created by using a photo of the actual cockpit panel and placing gauges over the photographic images. While we were doing this, we noticed that the switch which controlled the parking brake, had a second position labelled up as “Anti Skid”. FS 2002/4 does not have an anti-lock braking system available. So in the interest of realism, Claudio Mussner created a gauge which causes the aircraft to randomly engage/disengage the left and right brakes, when the main brake is applied under certain speed, weather and surface conditions. This simulates the aircraft skidding under braking and is enabled by default. To activate the “Anti Skid” system, simply left click on the switch to the right of the Gear lever on the main panel, and set the switch to the middle position. Setting the switch to the up position engages the parking brake.  As in real life, skidding only occurs when the conditions are right. So it is not necessary to have the “Anti Skid” switched on all the time.

 

There is one other feature in all variations, which is only visible in the 3D views. But due to a bug in FS2002 (not sure about 2004), may not work all the time. To see this at its best (if it works), go to the Virtual Cockpit view and press “Shift + E then 2” (rear canopy, cargo door etc). But I’m not going to tell you what it does. I’ll leave it as an Easter egg.
