February 2020 Update

The Invite-Only Beta is almost upon us, so it is a great time for another development update!

Pending final bug fixes, we will be sending out the approval emails to the invited users soon. If you are lucky enough to get one, you will be authorized to access our software at the time you receive the email. Those who make it into Phase 1 will receive invite codes for Phase 2 to distribute at your discretion, but those codes will not be immediately available. We will keep you posted on when they become available to distribute.

Here is a quick recap on the original plan for Invite-Only Beta, Phase 1 and what may or may not have changed since the announcement was first released:

  • Pilots will require an invite code and subsequent approval in order to participate
    • Status Update: This is still the case. All available invites have been distributed and those who received an invite are patiently waiting for the approval email, which will come soon.
       
  • ATC will be hand-picked by POSCON staff and will be required to sign an NDA
    • Status Update: This is still the case. One thing to note, however, is that we will most likely be very slowly implementing ATC. In fact, the first couple of weeks will most likely see little to no ATC coverage on the network as it still requires some additional dev work.
       
  • Operating times will be schedule limited
    • Status Update: This is no longer true. We plan to have the server up and running 24/7 as we have separated our development and production environments. We will inform everyone of scheduled down times when we make updates to the production servers.
       
  • Number of users was planned at between 500-1000
    • Status Update: This is still the case; we have invited between 600-700 users to Phase 1.
       
  • NDA is not required for Invite-Only Beta, Phase 1
    • Status Update: This is still the case. You are not required to sign a non-disclosure agreement (NDA) unless you are hand-picked to be an ATC. We will continue to maintain a select group of NDA pilot beta testers to test new features in our development environment.

Having said all that, now I want to take some time to outline features that made it into this phase. I think outlining these features is an important part of the process of managing expectations.

Voice System

One of the main blockers that prevented us from releasing POSCON sooner was the decision to completely rewrite our voice system. Six months ago we were using the TeamSpeak 3 SDK for our voice infrastructure, but we decided using TeamSpeak 3 would limit our technical growth into the future.  As a result, we opted to get rid of TeamSpeak completely before any sort of public release. Over the past few months we have worked tirelessly to develop our very own custom infrastructure and I am happy to report that it is now completed. Our voice will have the following features at Invite-Only release:

Voice Server Supports:

  • Many simultaneous connections.
  • Ground-based transceiver locations; there are currently 4,667 locations entered into our database.
  • Propagation of transceiver locations to the Radar Client.
  • Option for separate PTTs per radio (e.g. VHF #1 and VHF #2), separate volume controls per radio, and separate audio devices per radio.
    • The server supports this, but the pilot clients do not support this yet.

Voice Effects Supported:

  • Full VHF simulation including:
    • 8.33 kHz and 25 kHz spacing.
    • Terrain line-of-sight processing.
    • Beat simulation.
    • End-of-transmission popping tones.
    • Wavelength simulation.

Website & Administration

Another factor that prevented us from releasing POSCON sooner was the decision to build out a custom Single-Sign-On or SSO. It became apparent, as we added new products and technologies to our software suite, that the generic open-source or even payware services would not meet our needs. I am happy to report that our custom SSO has been completed and is fully functional. Here are some additional web features we will release with:

  • GDPR compliance.
  • A support system.
  • Basic flight statistics.
  • ICAO 2012 formatted flight plan form:
    • An integrated help tutorial is provided on the page.
    • The form validates while entering data.
  • Feedback and generic points system.
  • Live Map used to view online traffic (updates every 2 seconds).
    • Users can leave feedback about each other using the map.
    • Moderators can initiate ghosting, disconnects, and bans using the Live Map interface.
  • Pilot Client Web UI, which can be accessed on any device with an internet connection (see below for more details).

Pilot Clients, Pilot Client Web UI, & Pilot Server

The Pilot Clients are by far the most completed products that we have in our software suite. They have been closely designed in parallel so that the features remain consistent across the various platforms. Once you have logged in to the network, the Pilot Client will send information about your plane’s location, altitude, attitude, as well as a number of the plane’s parameters such as gear and flap deployment, engine RPM, state of various beacon and navigation lights, transponder mode and code, etc. The Pilot Clients also receive similar information from the network about aircraft that are within range of your plane. This information is used to draw 3D models of the aircraft at their correct position and orientation. The information is also used to populate various datarefs so that your aircraft’s TCAS system will be aware of nearby planes.

In addition to the aforementioned features, the Pilot Clients also feature:

  • Enhanced ground-clamping using various methods for a smooth experience regardless of differences in terrain.
  • Model matching. Here is how we handle model matching with the various platforms:
    • For X-Plane, the models are distributed with the pilot client itself and contain custom model matching logic.
    • For FSX/P3D, we have integrated the FLAi model set through our Launcher Client application (see below for more details).
  • ICAO equipment and airline code validation.
  • Accurate ground speed monitoring (X-Plane Only).
  • VHF push-to-talk activation indications.
  • AI model sounds and controls (X-Plane Only).
  • The ability to control the maximum number of AI planes that will be displayed.
  • In-game notification of ghosting and disconnects with explanations.
  • The ability to manually toggle ghost mode or request to unghost.
  • Automatic detection of change in aircraft.

The Pilot Clients will automatically ghost for:

  • Sim rate increase, entering slew mode, using replay mode, or deliberate pausing (this can also sometimes be triggered by accessing a sim menu).
    • If you are on the ground and not moving, pausing is allowed.
  • Connecting on or re-positioning to a runway (through a menu) will prevent connection or disconnect the user as applicable.

Pilot Client Web UI Features:

  • Some functions of CPDLC (Controller-Pilot Data Link) will be operational such as the login function and automatic squawk code assignment.
  • Real world D-ATIS (Digital Automated Terminal Information Service) broadcasts are integrated and can be requested in real-time by pilots.
    • The voice portion of D-ATIS is not working yet, only the text portion.
  • METAR and TAF reports can be requested in real-time by pilots.
  • Radio syncing.
  • Ghost and unghost toggle.
  • Disconnect.

Pilot Server Supports:

  • Many simultaneous connections.
  • A variable update rate based on range. When in close proximity to other aircraft, models will update 15 times a second for a smooth visual experience.
  • Airspace awareness. The server can determine a planes position in relation to defined airspace boundaries (both vertical and lateral). This is a very unique feature not implemented on any other network. In the future, this will enable POSCON to build many other features using this core server functionality.

Launcher Client

The Launcher Client is the centralized hub to keep you up-to-date on everything related to POSCON. This product was designed around the idea of "platform software" similar to what Origin, Steam, and other gaming platforms offer. The POSCON Launcher Client mirrors the content contained in the POSCON HQ, but with enhanced functionality: 

  • The ability to download, install, launch, and update all available network software.
  • The ability to switch between development and production environments (for NDA testers only).
  • Token authentication. Once you enter your username and password once, the Launcher Client will take care of the rest.

That's it for now, we hope you enjoyed this update. In the near future we will post a list of frequently asked questions that should help first-time users when accessing the network. If you have any questions you think would be a good addition to this list, feel free to comment below!

Thanks for all the support over the last few years, it continues to keep us motivated!

      Latest Entry

      By Andrew Heath,

      On April 1st, 2020 we officially began approving invites to the POSCON Invite-Only Beta. We are now almost two months into our release and it still brings me great excitement every time I see a new user experience POSCON features for the first time. We learned a great deal in the first few days and weeks after the initial release. One thing that became abundantly clear was that we need to have a central location to refer users to in regards to what features are functional, what features are still in development, and what features are planned for the future. In addition, there still seems to be some confusion surrounding the invite process, so I am going to attempt to clarify all these items in this development update.

      Before I began, I think it is worth mentioning that we created a Frequently Asked Questions (FAQ) area that may contain answers to some of the questions that may not be answered in this blog post.

      While there is no doubt that we have deviated from the FSExpo 2019 Roadmap to Release timeline, we are doing our best to keep on track. Right now, I think it is safe to say we are in Invite-Only Beta, Phase 2. Here is a quick recap on the original plan for Invite-Only Beta, Phase 2 and what may or may not have changed since the announcement was first released:

      • Pilots will require an invite code and subsequent approval in order to participate
        • Status Update: This is still the case. Currently, any approved member with access to the network also has the ability to invite two additional registered users to the service by clicking here. Once invited, those members will be placed into a holding pattern until they are approved by the POSCON staff. There is no set time frame on when these approvals are distributed - we approve people when the team feels comfortable to receive additional members. This two-step process was designed to meter the flow of incoming members and minimize the amount of support requests we receive. More information on the invite process is discussed below.
           
      • ATC will be hand-picked by POSCON staff and will be required to sign an NDA
        • Status Update: This is still the case. We have been testing ATC regularly now, but we rarely advertise when or where we will be conducting these testing sessions. This strategy is employed on purpose in order to not overwhelm the controllers as they test new features. On a few occasions, we have given some advance notice of when ATC will be online, but right now those instances are rare.
           
      • Operating times will be schedule limited
        • Status Update: This is no longer true. Before we released, we separated the network into a development environment and a production environment which enables us to minimize interruptions to the users as we add new features. With the exception of a few hot-fixes in the early days after releasing, we have made considerable effort to inform all beta testers of scheduled maintenance well in advance of a server restart. In order to facilitate this, we created a System Status Monitor page which can be used to view the status and scheduled down times of our applications: https://status.poscon.net/
           
      • ATC coverage will be limited to areas selected by POSCON
        • Status Update: This is still the case. ATC testing has been limited to the areas where the facility data is most developed; however, our Facility Data Team has been tirelessly working on other areas around the world as well. Here is just a brief overview of what they have done:
          • 170 FIRs have been worked on.
          • 7856 independent ATC sectors have been created.
          • 7053 independent VHF transceiver sites have been located and entered into our database.
          • 1801 independent radar sites have been located and associated with 73 different radar types.
          • In addition to the above, below are just a few images of the FIRs that have been worked on:

      • Number of users was planned at between 1000-2000
        • Status Update: This is still the case. As of May 23rd, 2020 we have invited and approved 1278 registered users.
           
      • NDA is not required for Invite-Only Beta, Phase 2
        • Status Update: This is still the case. You are not required to sign a non-disclosure agreement (NDA) unless you are hand-picked to be an ATC. We will continue to maintain a select group of NDA pilot beta testers to test new features in our development environment.

       

      Invite Process - How does it work?

      As mentioned earlier, the invite process consists of two steps: INVITED and APPROVED. Here is how it works:

      1. Lets assume you joined the POSCON Public Discord first and then realize you are interested in joining the network. If this is the case, you are considered an "Enthusiast" and will be assigned that tag automatically in our Discord server.
      2. Now you decide to register at https://www.poscon.net and complete the checklist items which include: ensuring your birthday is set correctly and your Discord ID is connected to your POSCON account. At this point, you are now considered a "Registered User".
      3. If you are lucky, you may be invited by an approved member as their guest and you will receive an email from POSCON. If this happens, you are still considered a "Registered User".
      4. Please wait patiently until you are approved by POSCON staff. When approved, you are now a "POSCON Member" and have access to our HQ website and are able to download the Launcher Client. This is the point at which you can now connect to POSCON.

      The time between steps 3 and 4 is an unknown. It could be a matter of days, weeks, or even months. It all depends on where we are at with our development and whether we are ready to accept new members.

      If you find yourself in limbo, the best thing you can do is join our Public Discord and participate in the discussions until you are invited and/or approved.

      • Working on integrating Live Map version 2.0 through the Launcher Client.

      Future Plans:

      • The plan is to embed the Pilot Client native user-interfaces directly into the Launcher Client. There will be no need to launch a the Pilot Clients anymore after this is completed.
      • Once the back-end work is completed for the above, a new user-interface will be needed to accommodate the integration.

       

      Next steps?

      The next step for the POSCON team is simple: we will continue to work hard on bringing you the next-generation flight sim network.

      While we do that, we encourage you to join our Public Discord and participate in the discussions there. Typically, the most up-to-date information about the project is released on our Discord first.

      That's it for now! If you have any questions that have not been answered in the FAQ or in this blog post, feel free to comment below.

      Latest Entry

      By Jarrett I. (1016071),

      I'm sure you've seen those four letters before - RVSM - and you may have a fundamental knowledge about the airspace, but do you know why it exists? Here are the answers to the most basic questions:

      1. Where do we find RVSM airspace? Higher cruising altitudes.
      2. What happens in RVSM airspace? Airplane separation is reduced vertically.
      3. Why does RVSM airspace exist? To allow more aircraft in the sky.

      There you have it... the simple definition of RVSM. Now, let's get technical:

      179238233_rvsmexample.thumb.jpg.7dec5a890cb6b0df0630858cc6783e10.jpgRVSM stands for Reduced Vertical Separation Minima and it's located between FL290 (29,000ft) until FL410 (41,000ft) inclusive. To understand RVSM, you must first understand what the vertical separation requirements were above FL290 before 2005. Prior to RVSM, aircraft were required to be separated by 2,000 feet vertically above FL290 due the possibility of altimetry errors at the higher flight levels. RVSM airspace allows for a reduction in vertical separation between qualifying aircraft in order to allow more aircraft to operate in crowded enroute airspace thereby allowing for more efficient traffic flows. Airplanes of course move a lot faster at higher altitudes though, so it is only natural that this little amount of separation may make even the most vigilant pilot a little nervous. However, it is important to note that before implementing RVSM, aviation authorities instituted a required set of parameters that must be met in order to operate in RVSM. If any of these parameters cannot be met before entering or while operating within RVSM airspace, the aircraft is required to advise ATC and exit RVSM.

      Before we get into other details about RVSM lets recall that in many countries, the East ODD and West EVEN rule applies to vertical separation. This practice ensures that two airplanes are never assigned the same altitude flying in opposite directions. In some regions that are geographically more north/south split such as Italy or Florida for example, they have elected to modify the rule to favor North ODD and South EVEN as the determining factor for vertical separation. Either way a region chooses to separate traffic, it is important to recognize that these rules exist are crucial to establishing a baseline for high altitude vertical separation.

      Now that we have covered the basic rule for opposite direction vertical separation, let's talk about what makes an aircraft RVSM approved. In order for an aircraft to operate in RVSM airspace, a certification is required from the governing agency of that nation (FAA, local CAA's, etc.), but the basic equipment that an aircraft should have operational include: an autopilot, two independent altimeters, a transponder with an altitude reporting capability, and an altitude alerting system. During flight in RVSM airspace, pilots will cross check their two independent altimeters to ensure the difference does not exceed a specified tolerance, which could range anywhere between 50ft to 200ft.  If any of these items malfunction during flight in RVSM airspace, notification to air traffic control is essential.

      Let's talk about air traffic controller's responsibilities in regards to RVSM airspace. Aircraft will have an equipment code in their flight plan assuring ATC that they are RVSM compliant and capable. If an aircraft alerts that they are no longer RVSM capable, ATC will have to either ensure separation of 2,000ft with that aircraft at all times or descend the aircraft outside of RVSM (below FL290).  However, just because an aircraft is not RVSM capable does not mean they can never fly between those altitudes. Many corporate jets are not RVSM capable but still request to cruise above RVSM airspace (e.g. FL430). In this scenario, the controller will climb the aircraft through RVSM airspace while ensuring 2,000ft separation is maintained between other traffic at all times. 

      On a final note, RVSM aircraft require a maintenance certification as well. The next time you start up your flight sim and connect to POSCON for IMG_20190825_235257469.thumb.jpg.8e83b29248a45ce99a0d2db21142efb2.jpgyour online flight simulation experience, take a look at the outside of your aircraft. Depending on the quality of the aircraft in terms of realism and study level, you should see what's called an RVSM critical area (see image to the right). Aircraft maintenance technicians must run specific tests and certify that everything located within this box meets the required RVSM tolerances, which are often stricter than in flight checks accomplished by pilots. Static ports, pitot tubes, and AOA vanes are small examples of what can be found in these boxes, of course, these are important functions that will assure RVSM tolerances when in flight. Pilots check this box during preflight inspections to ensure this critical area is free of residue, damage, dents, or other non-normal appearances on the components in the boxed lines.

      On POSCON, our air traffic controllers are well trained on RVSM procedures. When flying online, ensure your aircraft is RVSM capable and make sure you indicate it properly in the flight plan equipment code section ("W" is the letter identifying that the aircraft RVSM capable). If you do not include "W" and are offered an RVSM altitude (it happens), simply say to ATC "Negative RVSM". And of course if you are having issues with your autopilot, now you know you are required to tell air traffic control.

      After reading this article, you should be confident answering when and why the "W" equipment code is required in your flight plan. It is true, there are far too many acronyms in the aviation world, but at least you got RVSM down! See you on POSCON in RVSM and don't forget the whiskey! (get it?)
