The zkv1000 is an instrument which concentrates some other instruments in only one single and simple interface. It is largely inspired from the famous display parts of Garmin Primus 1000. Once said, the zkv1000 is definitively *not* a exact replica of the Garmin Primus 1000, and isn't intended to be one. Sorry about that.
Depending of your aircraft you may have in your cockpit different configurations, and some unavailable entries. Even we are ina sim, so there is no limit in the way to get full instrumented glide plane it may be interesting to limit the use of certain functions depending of the aircraft. This has to checked with the aircraft maintainer, or if you feel free with the GPL licence you may modify the aircraft to get the desired functions to work (see installation guide)


There is two devices for now: MFD and PFD. You may find in your aircraft a configuration with only one of those, one of each or one MFD and two PFD. But there may be other configurations if the aircraft maintainer has decided it.

Flight Instruments

Airspeed indicator

The indicated airspeed tape is in knots and can show up to 1000 knots. The black pointer shows the current IAS.
On the tape major ticks are shown at 10 knots interval, minor ticks at 5 knots interval. A pink trend vector shows the estimated speed in the next 6 seconds (in the limit of +/- 30 knots).
There may be some Vspeeds marks (pink, text in white) specific to the aircraft (cf installation guide). It is possible to modify these values of the Vspeeds references by using the softkeys menu TMR/REF which make a window appear in the right down corner of the screen, and then navigating to the value to change it as described in UI code and usage chapter.
The black pointer will take a red color if IAS exceeds the defined Vne.
The true airspeed is shown under the speed tape, and the ground speed. Both are in knots.
If the device is configured with stall angle of attack (see installation guide) then the softkeys menus PFD > AOA/WIND > AOA ON shows up a window just near the airspeed tape. This indicates the current normalized angle of attack, a LightBlue mark shows the best normalized angle of attack for approach.
The softkey menu PFD > AOA/WIND > AOA AUTO make the AoA indicator showing up automagically if the gears are down and flaps out.
The softkey menu PFD > AOA/WIND > WIND > OPTN1 shows up the direction of the wind relative to the aircraft (heading and speed)
The softkey menu PFD > AOA/WIND > WIND > OPTN2 shows up the direction of the wind with front and cross wind components
The softkey menu PFD > AOA/WIND > WIND > OFF hides the wind indicator window.

Altitude indicator

The altitude tape is in feet, and shows from -990ft to 99990ft. The black pointer shows the current indicated altitude (determined from the air pressure), 20ft graduated. A trend vector indicates the readched altitude in the next 6 seconds in the limit of +/- 300ft.
The barometric setting is shwon just under the altitude tape. It is graduated in inHg by default, but this can be modified to hPa using the softkey menu PFD > HPA, and back to inHg via menu PFD > IN. The setting to standard barometric value (29.92inHg or 1023hPa) can be automatically set by the menu PFD > STD BARO. The barometer setting is essential and can be done by turning the BARO knob in front of the device (left side, under the COMM knob).
The selected altitude is indicated by a lightblue bug along the altitude tape. It is blocked at the upper or lower corner of the tape until the tape has in its range the selected altitude. While the selected altitude isn't in the +/- 300 ft range a black box indicate the selected altitude above the altitude tape. This box disappear when the indicated altitude is +/- 100 ft of selected altitude.

Vertical speed indicator

The vertical speed indicator is on the right just near the altitude tape, and is graduated with major ticks every 1000 ft/min, and minor ticks every 500 ft/min.
A black pointer containing the vertical speed with 10 ft/min precision moves along the non-moving tape. If the vertical speed exceeds +/- 4500 ft/min the pointer is locked to the upper/lower of the non-moving tape, and the vertical speed is detailed inside the pointer.

Attitude indicator

Pitch scale is graduated 10° up to 80°, with minor marks 5° interval up to 25°, and every 2.5° below 20° pitch. The horizon line is part of the pitch scale, and represents a pitch of 0°.
The roll scale is the 120° arc. The inverted triangle represents 0° roll. Major ticks represent 30° and 60°, minor ticks represent 10°, 20° and 45°.
The slip skid indicator is the bar beneath the roll pointer. The Slip Skid indicator moves laterally away from the pointer to indicate the lateral acceleration.

Horizontal situation indicator

The HSI displays a rotating compass card in a heading-up orientation. Letters indicate the cardinal points and numeric labels occur every 30°.
Major tick marks are at 10° intervals and minor tick marks at 5° intervals.
A digital reading of the current heading appears on top of the HSI, and the current track is represented on the HSI by a magenta diamond bug.
The HSI also presents turn rate, course deviation, bearing, and navigation source information.

Course Deviation Indicator

The HSI contains a Course Deviation Indicator (CDI) with course pointer, TO/FROM indication and a sliding deviation bar.
GPS, VOR1 and LOC1 have single line arrow, while VOR2 and LOC2 have two lines arrow.
GPS CDI is available only if a course has been set via the route manager, VOR and LOC show arrow when the active NAVAID is received.

Adjust heading

Turn the HDG knob to adjust the heading, doing so the heading bug will be positionned along the compass.
A window showing the desired heading is shown for 3 seconds.

Adjust selected course

Turn the CRS knob to adjust the desired course for VOR and LOC



NAV stack is on the left on each device. It is composed by

  • 1 switch button
  • 1 tuning knob
  • 1 display with 4 frequencies

Frequencies are organized like this

standby NAV1 | active NAV1
standby NAV2 | active NAV2

The tuning is done on the selected NAV which is the one with the standby frequency in blue. The tuning step is 0.25 MHz (or 1.00 MHz with the use of Shift) in the range 108.00 to 118.00 MHz


The COMM stack is on the right side on each device. It is composed by

  • 1 switch button
  • 1 tuning knob
  • 1 display with 4 frequencies

The frequencies are displayed as follow:

active COMM1 | standby COMM1
active COMM2 | standby COMM2

The tuning frequency is the one in blue, the step is 0.025 MHz (0.500 Mhz using Shift) from 118.025 to 123.975 MHz


Flight Management


The map content can be modified by using INSET softkey on PFD, and MAP softkey on MFD, then by activating or de-activating each layer.

The map orientation and zoom can be modified by pressing the MENU button.
Map orientation and zoom configuration
The zoom level is an number between 7 (largest range) to 13 (smallest range). The range calculation depends on two other factors: latitude and size of the screen (eg. EIS size). Here's a table for ranges without EIS and for 40° lat:

Zoom index Approximative range of Y axis, in NM
7 194
8 97
9 49
10 24
11 12
12 6
13 3

Four orientations are available:

  • NORTH UP: in this configuration the aircraft symbol rotates, the map is aligned with North up
  • TRK UP (Track Up): if aircraft is on the ground the aircraft symbol doesn't rotates and is up, map rotates to represent the heading of the airplane. Airborn, the top of the map is aligned with the current ground track.
  • DTK UP (Desired Track Up): alignes the map with the desired course (only available if desired course has been set)
  • HDG UP (Heading Up): the top of the map is the current heading of the aircraft

When the desired zoom and orientation are selected, validate by pressing ENT button. Pressing the CLR exit the modification window without saving the changes.


You have to choose the map background you want to be displayed. For this you have to use the options in your .fgfsrc. This is subject to change in near future in order to allow to change the maps while the device is running. For now there are some options to tells the zkv1000 which map you want:

LFBT - tiles from
  • without any configuration (default settings), tiles from

LFBT tiles from (registration needed)
  • If some more information are needed in URL (as registration key) you may want to use the /sim/online-tiles-apikey property

LFBT - tiles from opentopomap
  • If there is no specific "type", please affect / char to property /sim/online-tiles-type

LFBT - tiles from (covering France only)
  • If the URL can't be easily standardized, you can create you own template with property /sim/online-tiles-template, you can use some tags from properties as {server}, {type} and {format}, where values come from respectively /sim/online-tiles-server, /sim/online-tiles-type and /sim/online-tiles-format:

(maps covering only France)


  • By default, protocol is https, so if you need http you'll need to use /sim/online-tiles-template
    (The follwing example doesn't display anything, tiles are empty around LFBT, need to investigate a bit)




Traffic announciator is shown as there is a traffic in sight, until there is no traffic at all


Inset map


Set screen brightness and body lighting

(screenshots to come one as soon as the highlighting system has been repaired)

On PFD without other windows opened, click on MENU key in order to make the System Settings windows displayed. You can use Inner FMS knob to adjust the brightness of the screen percent by percent from 0% which is very low, to 100% which is adapted to very shiny conditions.

During night, you can also make the ZKV1000 body being lighted (keys, softkeys and knobs descriptions). To do so, select the Light using Outer FMS knob, and adjust the lighting with the INner FMS knob. There are four level, from 0 which is light off, to 3 which is very luminous. Adjust to the level you are the most comfortable.

Using MENU or CLR key close the window.

The settings aren't stored for future flight sessions
