Thanks

Thanks to www2 the modeller of the GDU104X project "Farmin/G1000" I can continue the work began many years ago with a nicer (and working) 3D model instrument. Thanks to him/her for the SVG basis file too.
Thanks to Hooray's nice efforts, and some examples ans snipsets of code here and there from the Canvas team.
Thanks to all FlightGear community for the funny project I let too many years off side...

Origin

The first ZKV1000, which was completly XML animated, was completly abandonned. Moreover the Nasal code became unmaintanable from my point of view. Not sure this one is better, but I think it is at least more modulable.

The origin is to simulate a Garmin Primus 1000, as near as possible of the documentation found.

But as we are in a simulation, the zkv1000 is definitly not a replica of the well-known G1000, as it takes the liberty to be integrated with some features that doesn't exit in the real device, as well as some real features aren't scheduled to be implemented. But, it should be easy to add or remove features in order to get the real device. This is GPL-2 license though :)

Objectives

There is no intention to provide a fully qualified G1000 in order to train or so, but this should be possible to be done from the zkv1000.

I'm particulary looking at these points:

  1. easy to implement new features
  2. optimized code (from my non-dev point of view...)
  3. easy to integrate in every cockpit with only few lines, and with easy use for the pilot
  4. near from the G1000 documentation but with some neat features added, and some unrelevant features in a sim removed

Installation

Just git clone https://sebmarque.hd.free.fr/git/seb/zkv1000 in your favorite Instrumentation-3d dir.
Then somewhere in the XML configuration of your aircraft, put only few lines as described below

Create the zkv1000 Nasal namespace

In the <nasal> place of your aircraft configuration

    <zkv1000>
        <file>Aircraft/Instruments-3d/zkv1000/zkv1000.nas</file>
    </zkv1000>

Actually this is where everything begins, please have a look at this code, it would help you to follow the script.

Set specific values for your aircraft

Specifics values for aircraft can be set via the aircraft configuration, in the <instrumentation> section, just add a section <zkv1000> and set here the needed values.

Vspeeds

To see the Vspeeds bugs or the IAS background color change (Vne), set the corresponding V-speeds in knots by adding in your <instrumentation><zkv1000> section the following lines (here are the numbers for the Lancair-235, values are not to be used in real life). If not set, defaults to 999 knots

    <alerts>
      <Vx>99</Vx>
      <Vy>110</Vy>
      <Vr>65</Vr>
      <Vglide>80</Vglide>
      <Vne>170</Vne>
    </alerts>

EIS

This parameter tells the zkv1000 which kind of engines equips your aircraft, and the associated EIS.
The Nasal script should include at least three things:

  • a method called displayClass.showEIS in which you initialize the EIS, especially by selecting the shown, hide, clipped and texts elements
  • a method called displayClass.updateEIS which is used to update the EIS display, it includes its own timer to refresh itself
  • a SVG object with ID EIS (generally the background of the EIS display).
    It should appears in the lists in displayClass.showEIS.
    This object is used to compute the map width, so it is important to set it on the left of the screen

There are three ways too put an EIS in MFD:

use one of the included simple EIS provided with the zkv1000

    <eis>
      <type>single-prop</type>
    </eis>

Defaults to none, available entries are the .nas files located in Nasal/EIS/ directory.

or use the one you specially have created for your aircraft

    <eis>
      <file>Aircraft/My-Nice-Aircraft/Nasal/EIS.nas</file>
    </eis>

or the on from another aircraft. Anyway if the EIS nasal file targeted doesn't exist, the fallback is the type none.

or you can give the absolute path (deprecated)

    </eis>
      <file>/home/foobar/fgfs-data/Nasal/testing-jet-jsbsim-EIS.nas</file>
    </eis>

Be aware that canvas.parsesvg uses only relative path and should not work properly if your .nas is outside of the FG tree.
If you want to add your own EIS, just copy the Systems/EIS/single-prop.svg, modify it to fit your needs, and refer to it in a function named displayClass.showEIS, another very important function is displayClass.updateEIS (example in Nasal/EIS/single-prop.nas)
You are even free to modify the softkeys map in order to get according menus, but this has to be described on another document (check Nasal/softkeys.nas).

No matter of the EIS width, as the map size and center are computed relative to the EIS width automatically.

Notes:

  1. you can use <file> or <type> indifferently, they are actually identical.
  2. later on the MFD Engine pages will be managed by the file specified in this section

Angle Of Attack (AOA)

You can specify the stall AoA in order to display it in the dedicated display.

    <alerts>
      <stall-aoa>15</stall-aoa>
      <approach-aoa>4</approach-aoa>
    </alerts>
  • Values are in degrees.
  • If <stall-aoa> is not specified or equals to 0 (zero) the AOA display won't be accessible.
  • The <approach-aoa> is optionnal, if present a blue marker is visible on AOA display (not in real GarminP1000)

3D models

In the definition of your flightdeck (here are the values for the installation in the Lancair 235 in which I develop the device) put it everywhere you want to

    <model>
        <path>Aircraft/Instruments-3d/zkv1000/pfd-pilot.xml</path>
        <offsets>
            <x-m> -0.023 </x-m>
            <y-m> -0.235 </y-m>
            <z-m> -0.028 </z-m>
        </offsets>
    </model>
    <model>
        <path>Aircraft/Instruments-3d/zkv1000/mfd.xml</path>
        <offsets>
            <x-m>  0.03  </x-m>
            <y-m>  0.06  </y-m>
            <z-m> -0.028 </z-m>
            <heading-deg> -15 </heading-deg>
        </offsets>
    </model>

You can put as many devices as wanted, but generally they are two (PFD+MFD) or three (2 PFD+ 1 PFD), can be only one which is useful when you just want the PFD or the MFD in your cockpit. The device are identified by a name, which should be unique unless they won't be independant. This name is set by one of the property in the XML model file (instrumentation/zkv1000/<NAME>/status), which is a property telling if the device is switched off or not (or in reversionnary mode, later). Actually there are only two "types of display": MFD or PFD, which is known by the first 3 letters of the name (case sensitive!) Other devices as keyboard or non-display can also exists, as long as they don't have a status property... Not sur I'm clear on this point though :)

Map tiles origin

By defaults the maps tiles come from https://maps.wikimedia.org, type osm-intl (please read https://www.wikimedia.org/wiki/Maps), but you can choose your favorite one if you've got one. I've tested opentopomap.org and thunderforest.com (my favourite). You can tell the zkv1000 the tile server, type and eventually apikey by using --prop: option while starting FlightGear session:

In case of apikey (or whatever added at the en of the URL):

    --prop:/sim/online-tiles-server=tile.thunderforest.com
    --prop:/sim/online-tiles-type=landscape
    --prop:/sim/online-tiles-apikey=?apikey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

or if there is no type, just use type /:

    --prop:/sim/online-tiles-server=a.tile.opentopomap.org
    --prop:/sim/online-tiles-type=/

The only used protocol is https (check Nasal/map.nas).

Switch it up

You can use the multikey (souvenirs, thanks to Melchior having that much expended this feature years ago :)) service by typing: :zo

The :z will be the multikey entry for all multikeys of the zkv1000.

  1. If you see a single red dot under the ZKV100O xxx init message (xxx = MFD or PFD), this is likely the sim is paused (press p by default to stop the pause).
  2. If you see multiple dots under the ZKV1000 xxx init message, something wrong happened, time to check console
  3. If you see only black screen on one of the screen, something really wrong happened, time to check console
