# vACDM # Installation ### Requirements To load and run the vACDM plugin you need to have the latest Visual C++ Redistributable installed: [https://aka.ms/vs/17/release/vc\_redist.x86.exe](https://aka.ms/vs/17/release/vc_redist.x86.exe) If the plugin should be offered within the default Euroscope Package for everyone, the Visual C++ Redistributable update should be recommended after installing Euroscope or before downloading the package. ### vACDM Plugin Setup The vACDM plugin will only work for an airport where the different parameters are predefined at the backend website. To work with the vACDM Plugin you should have a basic knowledge of the ACDM procedure. **Load List Setup:** Right now we offer a predefined **Startup**, **Departure** and **Taxi-Out List** for every FIR Euroscope Package [**here**](https://dms.vatsim-germany.org/s/xmnYW7fKdXy5Lei "vACDM Plugin"). Within the Langen Package the vACDM plugin is already included. For all other packages you can simply load the provided file for the mentioned lists above via OTHER SET => Settings files setup =>Startup list configuration / Departure List Configuration / Taxi Out List Configuration. As the vACDM plugin should primary used by Delivery, we recommend to use the Startup List to display the different main items. If the different items are not required all the time they should be disabled by using the Euroscope List filter "F" at the top left corner of every list. The following setup is recommended and predefined:
**Tag Item** | **left click** | **right click** |
**EOBT** | cornfirm TOBT | set TOBT |
**TOBT** | TOBT menu | set TOBT now |
**TSAT** | set ASAT + Startup State | set Startup Request |
**ASRT** | set Startup Request | set ASAT + Startup State |
**ASAT** | set ASAT | set ASAT + Startup State |
**AORT** | Request Offblock | Ground State menu |
**AOBT** | Request Offblock | Ground state menu |
**TTOT** | -- | -- |
**EXOT** | modify EXOT | -- |
**Abbreviation** | **Time** | **Meaning** |
**EOBT** | Estimated Off-Block Time | Off-Block Time filed within the flightplan (planned in advanced). |
**TOBT** | Target Off-Block Time | Time where the outbound is actually ready and would **like to go offblock.** |
**TSAT** | Target Startup Approval Time | Time where the outbound is **allowed to go offblock** (+/- 5 minutes). |
**ASRT** | Actual Startup Request Time | Time where the outbound is fully ready and requested startup. |
**ASAT** | Actual Startup Approval Time | Time where startup is approved by ATC. |
**AORT** | Actual Off-Block Request Time | Time where the outbound requested offblock (pushback or taxi out). |
**AOBT** | Actual Off-Block Time | Actual Off-Block Time. |
**EXOT** | Estimated Taxi Out Time | Taxitime from the position to the assigned runway, including pushback. |
**TTOT** | Target Take-Off Time | Take-Off time based on the airport capacity. **Outbounds do not have to stick to that time!** Departure before and after is possible without any timeframe. |
**CTOT** | Calculated Take-Off Time | Time window for take-off by Eurocontrol, based on TTOT. **Take-off** is only possible at this time with **-5 to +10** minutes. Consideration of enroute and arrival capacity at destination airport, not at departure airport! |
When using vACDM, the **enroute** and **startup clearance** should be issued **seperately**.
Enroute clearance can be issued whenever the pilot requests it. Startup should only be approved when the pilot is able to push and/or start the engines within the next 5 minutes. An **additional presentation** regarding ACDM is available [**here**](https://dms.vatsim-germany.org/s/RmqnkbqxpSWoB8B "ACDM Presentation"). ### vACDM Master In order to be able to edit times in the plugin list, the ATC has to insert `.vacdm master` inside the Euroscope console. The default setting is always read only.Before you set yourself to master be sure to set your runway configuration in Euroscope correctly!
### Set TOBT vACDM works best when the TOBT is up to date and the pilot is completely ready at that time. The filed EOBT is always a good first guess. If there is no valid time available (empty TOBT, time in the past or to far in the future - TOBT orange), ATC should ask the pilot if he has a time where he is fully ready for pushback. That time should be entered as TOBT. Pilots are able to set their TOBT at [vacdm.vatger.de](https://knowledgebase.vatsim-germany.org/vacdm.vatger.de "vACDM AVDGS") where they can see their TOBT, TSAT, planned runway and SID. More information here: [VDGS](https://knowledgebase.vatsim-germany.org/books/vacdm/page/vdgs "VDGS")Confirmed TOBT (by ATC or pilot) is displayed in dark green.
### Issue Startup As soon as the **TSAT** is displayed in **dark green**, **startup** can be issued. If the pilot calls in before that and it is still shown in **light green**, the TOBT can be set to now and the TSAT will be recalculated. That new TSAT will not be later than the previous one, but might be earlier if there is a gap in the sequence. If ATC can assume that there will be no benefit in updating to an earlier TOBT (e.g. due to a high traffic load and a small time difference to the TSAT), the TOBT does not need to be updated as the TSAT might remain the same. As soon as the outbound is ready and **startup can not be issued** e.g. due to TSAT, the **ASRT** should be set to mark the aircraft requested startup. You will see a "R" next to the TSAT to indicate the outbound is ready. If the **TSAT** is shown in **orange**, the pilot missed the window for startup and the TOBT has to be set to now to **recalculate** a new TSAT. ### TTOT Monitoring To check if the airport runways are within the capacity limits you could check the TTOTs (within the startup/departure and taxi out list). As long as the TTOT is green, the outbound is still within the calculated timeframe(that might be up to +9 minutes after TTOT). If the TTOT is orange it takes longer as calculated. A few orange TTOTs are still fine for an efficient traffic flow but it shouldn't get too much. ### Delay Startup Depending on the traffic situation it might be necessary to delay startups even if vACDM is used (e.g. Tower does not get the traffic out as expected - many orange TTOTs). Initially you should delay startup within the +/- 5 minutes range according startup. > DLH123 expect startup according TSAT + 5 If more delay is required, the runway capacity need to be reduced by an admin. # vACDM Colors There are several colors for the different items that are important. Colors can be changed within the settings. Below you can find the items with the different colors and it's meaning for the ACDM process. **EOBT / TOBT:****Color** | **Meaning** |
light green | TOBT in the future, not confirmed |
green | TOBT confirmed, not expired, within the next hour, difference between TOBT and TSAT less than 5 minutes |
light yellow | TOBT not confirmed, difference TOBT and TSAT more than 5 minutes (startup delay) |
yellow | TOBT confirmed, difference TOBT and TSAT more than 5 minutes (startup delay) |
orange | TOBT expired or further in the futere than 1 hour |
gray | Outbound has startup |
**Color** | **Meaning** |
light green | NOW < TSAT - 5 minutes |
green | NOW = TSAT +/- 5 minutes |

gray | with ATOT |
**Time** | **Name** | **Time Frame** |
EOBT | estimated off-block time | ±5 minutes |
TOBT | target off-block time | ±5 minutes |
TSAT | target startup approval time | ±5 minutes |
CTOT | calculated takeoff time | -5 minutes / +10 minutes |
When prefiling from SimBrief, an EOBT will automatically be added to your flight plan. This time will be calculated based on when you start creating your SimBrief flight plan + 30 minutes. If you plan to depart earlier or later, it is recommended to change this time.
##### TOBT (Target Off-Block Time) During the preparation of the aircraft, you might realize that you will be ready earlier or later than your original estimate. Keeping your TOBT up to date will help ATC to reduce delays and ensure a smooth operation. When you set a TOBT, ATC will treat it as a confirmed time and calculate your TSAT based on it. If you realize during any part of your preparation that a **new estimate will differ more than 5 minutes from the previous one**, you should set a new TOBT.To set your TOBT, **we recommend using the [vACDM pilot interface](https://vacdm.vatsim-germany.org/ "vACDM pilot interface"), which allows you to set it on your own**. If you did not set a TOBT yourself already, ATC will have to ask you to report your TOBT, which will lead to unnecessary frequency congestion.
It is generally good practice to **set your initial TOBT 20-30 minutes in advance** and **request enroute clearance 10-15 minutes before your TOBT** to ensure the information is available for ATC planning and that the controller can inform you of any potential delays or slot restrictions ahead of time.
If you do not set a TOBT, ATC might not be able to approve your startup right away when you are ready. Especially during periods of high traffic, **not setting a TOBT ahead of time can result in delays for you**.
##### TSAT (Target Startup Approval Time) This is the time when ATC is planning to approve your startup. Keep in mind that it is ultimately **your responsibility as the pilot to request startup within the TSAT window; don't rely on the controller to call you for your startup**. You can always find your current TSAT on the virtual VDGS in the [vACDM pilot interface](https://vacdm.vatsim-germany.org/ "vACDM pilot interface"). In an optimal situation, your TOBT and TSAT will be at the same time. However, if there are more aircraft wanting to depart than the airport can currently accommodate, startups will be delayed and your TSAT will be at a later time than your TOBT.If you **miss your TSAT window (TSAT ± 5 minutes)**, the gap for departure is lost and a new TSAT has to be generated. Be aware that your **TSAT can improve** (and occasionally also worsen) depending on the general traffic situation and other aircraft's TOBTs.
Pushback needs to be **requested within 5 minutes of your startup approval**. At taxi-out positions you have **10 minutes to call for taxi**. After that time the startup approval is invalid and you will be told to recontact Delivery, who has to generate a new TSAT.
##### CTOT (Calculated Take-Off Time) This is the actual slot. On VATSIM, you will usually not be issued a CTOT, so it is not a big deal to depart a little bit later or earlier than what ATC had originally planned. However, **during some busy events with slot bookings or if there are flow measures in place for your route, you will be given a compulsory CTOT** and have to depart in this CTOT window (CTOT - 5/+10 minutes). When you are given a CTOT, it is very important to meet it as another slot might not be available for over an hour. #### How do I use the vACDM pilot interface? To access the [vACDM pilot interface](https://vacdm.vatsim-germany.org/ "vACDM pilot interface"), you need to log in using your VATSIM account. The system will then search for your flight in the vACDM database. [![Searching for Callsign.jpg](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/scaled-1680-/searching-for-callsign.jpg)](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/searching-for-callsign.jpg) ##### Setting your TOBT Next to the virtual VDGS, you can update your TOBT based on your current estimates. It has to be entered in UTC. [![Set TOBT.jpg](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/scaled-1680-/set-tobt.jpg)](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/set-tobt.jpg) Once you have set your TOBT, it will show as confirmed. We ask pilots to **confirm their TOBT at least once** and **update it every time it changes by more than 5 minutes**. [![TOBT confirmed.jpg](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/scaled-1680-/tobt-confirmed.jpg)](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/tobt-confirmed.jpg) ##### Virtual VDGS Once your flight is logged in the vACDM process, you will see the virtual VDGS with your flight's current departure information. [![VDGS.png](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/scaled-1680-/vdgs.png)](https://knowledgebase.vatsim-germany.org/uploads/images/gallery/2023-04/vdgs.png)Keep in mind that the departure information on the virtual VDGS will only be correct **once you have set a TOBT and have received your enroute clearance**.
#### Where is vACDM used? vACDM is **currently in beta testing**, so it will only be available at a limited number of airports. At the moment, you will see the system in use primarily at the following airports: - [Frankfurt/Main (**EDDF**)](https://knowledgebase.vatsim-germany.org/books/airports-langen-fir-edgg/chapter/eddf-frankfurtmain "EDDF Pilotbriefing") - [Köln/Bonn (**EDDK**)](https://knowledgebase.vatsim-germany.org/books/airports-langen-fir-edgg/chapter/eddk-kolnbonn "EDDK Pilotbriefing") - Düsseldorf (**EDDL**) - [Stuttgart (**EDDS**)](https://knowledgebase.vatsim-germany.org/books/airports-langen-fir-edgg/chapter/edds-stuttgart "EDDS Pilotbriefing")Keep in mind that not all controllers might be using this system yet. If you are unsure whether a controller is working with vACDM, **don't be afraid to ask them** - when the system is in use, it will usually be **announced in the ATIS**.
