V-Speed Gauge. A V-speed gauge that when installed into an aircraft panel will calculate the V1, V2 and V3 take off speeds for civilian aircraft, regardless of load or flap settings. The readout will be displayed in an easy to read format in the 2D cockpit, and also includes aural sounds for 80 knots, V1, Vrotate, and V2 speeds, at which point the VSI should show a positive rate of climb. Original gauge for FS2004 by Jacob Larsen (JEL), and modified for FSX by Anthony Eades.

This software is FREEWARE and may not be included in any form of payware!
Freeware-addon designers can include it in their own freeware-addons if they like.

This gauge has been successfully tested on the following type aircraft:

Boeing 737-200
Boeing 737-800
Boeing 757-200
Boeing 747-400

It should work with most standard commercial jetliners.

The auto-calculated Vspeed's depend on the aircraft's air-file, but are not really aircraft-specific as such. The Vspeed-values are average approximations for sim-use only, and are not neccessarily true to the various individual real-life aircraft-specifications.

Using this gauge should give you good clean takeoff's at any weight and fuel-load setting.

The gauge is not for GA-aircraft, military or special-operation's aircraft. Only commercial jetliners (you are free to try it on any aircraft ofcourse, but dont expect it to work properly on others than those mentioned above, although it may.)



How to install this gauge into an FSX aircraft cockpit panel:

Having selected the aircraft where you want to install this gauge, add the following line to the end of [Window00] in the panel.cfg which you will find in the aircraft panel folder:- (Make a copy of your existing panel.cfg first)

(Change xx to the next gauge number.)

"gaugexx=JELAIR/Sound3!dsd_xml_sound3, 20,20,,,./gauges/JELAIR/Sound.ini"

Check and make certain you have copied this exactly, including all the commas and full stops - copy/paste is the best option.

Now add a new window below the last existing window in... [Window Titles].
i.e. "Windowxx=JELAIR-Vspeeds" (where xx is the next number after the existing windows.)

Then add the following at the end of the windows listing and before any Vcockpit windows:


gauge00=JELAIR!JEL-Vspeed, 0,0,250,25

where xx is the same number of the Windowxx=JELAIR-Vspeeds in the windows listing.

Make sure you save your new panel.cfg.

The line - "visible=1" - ensures that the v-speed read out is visible when you load the aircraft. If you do not wish to see this you can either then "close" the read out window, or you can change the line in the cfg to read - "visible=0".
This will not change the operation of the gauge except it will not be visible on loading the aircraft. It can still be accessed from the menu bar/views.

Make sure you copy the files to their right locations! You can do this manually.

#1: Copy the files manually. Here's where the files belong:

"dsd_xml_sound3.gau" belongs to the main gauges folder (where you probably have several thousand files located already).

#2: The folder "JELAIR-sounds", which is a sub-folder of Sound, needs to be placed intact into the main FSX Sound folder.

#3: The folder "JELAIR" (which is a sub-folder to the main gauges folder) can be copied, along with its contents, also directly into the main gauges folder (it wont overwrite any of your own files).
9 files belong in this JELAIR sub-folder:


These are the aural callouts. If you want to, you can record you own voice and replace these files.


The gauge should become visible on the left side of the screen, at the top left hand corner.

It should look something like this:

V1 xxx / Vr xxx / V2 xxx

Where 'xxx' is the calculated V-speed in knots.

The 3 values are automatically calculated depending on your aircraft weight, and its flap-setting. The heavier you are, or the more you retract the flaps, the higher the values will become.

V1: This is the 'go/no-go decision' velocity marker. When you reach this speed, during your takeoff-run, you _must_ continue with the takeoff even if you get an engine-failure.

Vr: This is the 'rotation' velocity marker. At this speed you should begin pitching the aircraft-nose up.

V2: This is the 'minimum safe takeoff-speed' velocity marker. At this speed the aircraft should produce enough lift to be able to climb at a safe pitch-attitude.

When you are cleared for takeoff and begin rolling down the runway, the following should happen:

At 80 knots indicated airspeed the co-pilot will say "80", at which time you should cross-check that your IAS-dial also reads 80 knots.

At V1-speed the co-pilot will say "Vee one", at which time you can nolonger abort the takeoff, but _must_ get airborne (even if an engine should fail)

Shortly after V1-speed the co-pilot will say "Rotate", at which time you pull the yoke-column back towards you to raise the nose of the aircraft.

At V2-speed the co-pilot makes the V2-speed call, and the VSI should show initial positive climb.

The co-pilot will call the V-speeds on every takeoff, and not just the first. However, the gauge must be opened atleast once before it becomes active. The gauge does not have to be visible for the aural callouts to work (at the pre-flight checks you can open it, then close it again, and that will be enough to make the co-pilot do the callouts during takeoff)

That was the user-manual in brief :)

Thanks for flying JELAIR :)

Hi. I used this application for pmdg 737 ngx. But it says 80 knots and immediately says v1, vr, v2. What do I have to fix? Could you help?

FATCATTue, 15 Mar 2016 12:32:15 GMT

I also just got the display without sounds for the Airbus. Followed the instructions carefully.

Hi .. il do all your readme file.. but i still cant hear the v1 or v2 after take off clereance.. Sory for my badenglish☺

Nope. Failed completely in POSKY's 737-200. Waste of space.
