There are features in the TFDi user manual that we will/do not deploy in our virtual airline. --- #### **Simulator Specific Settings** ##### **Microsoft Flight Simulator** We recommend that "Automatic PIREP submission" be disabled -- this will result in invalid flights being submitted to Walker that will be automatically rejected. Tracking Provider will be set to "simconnect". [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1743375379469.png) ##### **X-Plane***If you have a VPN program installed, it needs to be connected, uninstalled, or you need to adjust the network adapter weight (according to Laminar this is a solution for those who need to retain a VPN but don't use it all the time) so that it will not interfere with XP UDP connectivity to 3rd party apps.*
We recommend that "Automatic PIREP submission" be disabled -- this will result in invalid flights being submitted to Walker that will be automatically rejected. Tracking Provider will be set to "xplane". [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1743375390969.png) 2\. You cannot run your simulator as administrator. If you have "User Access Control" enabled on your PC and you received a popup asking you if you wanted to run X-Plane, MSFS, or Prepar3D and you clicked yes -- your application has been hard set to "run as administrator". If you attempt to try and fly you will be presented with this error. [](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/uploads/images/gallery/2023-09/image-1693575958087.png)| [](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/uploads/images/gallery/2023-09/image-1693576050086.png) | **How can I fix this?** You will need to find your executable file (*not your shortcut file)*, right click and choose properties, compatibility, and uncheck the "Run as Administrator". Another option is to also completely disable 'User Access Control' but that is your choice. You can watch this video and decide: [https://www.youtube.com/watch?v=D2XlznYAcAQ](https://web.archive.org/web/20241119071819/https://www.youtube.com/watch?v=D2XlznYAcAQ) If you continue to have problems after doing this, you will need to contact TFDi at the support links above. |
*If you choose to not create and/or login with a TFDi account, you will not be visible on their map under our virtual airline. You will also be unable to access your premium features you purchased from TFDi.*

--- ##### **Main Page** The **Main Page** screen containing your **name, pilot ID,** and **rank** will appear together with your personal statistics – **total hours, total flights** and **average landing rate**. You will also get notifications in this panel as well as be able to logout using the button under your name and rank.*For a new, first time Pilot, these fields will be blank because no flights have been completed.*
To navigate through the remaining sections within *smartCARS*, click the icons in the left column. You can drag these icons around as well to create your preferred menu layout. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425325394.png) --- ##### **My Flights** In order to see the flights that you’ve completed a **[bid](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/books/2-training/page/flights-my-bids)** from the crew site, click on this [](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/uploads/images/gallery/2023-07/image-1688300033767.png)icon on the left side of the screen. You no longer need to start a flight manually, smartCars3 should automatically detect you are at the departure airport and start the bid. In case you have multiple bids from the same origin airport, SC3 will ask which bid you would like to use. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425562280.png) **NOTE:** *If you've completed a Bid and it doesn't show up, click the [](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/uploads/images/gallery/2023-07/image-1688300076378.png)icon on the top right.* [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425341666.png)*Please read this section in it's entirety, the way smartCARS 3 operates is completely different than smartCARS 2.*
In smartCARS 3, a pilot is no longer required to enter their route, cruise altitude, and load. This information comes from a couple different sources within the Walker Air Transport bid as well as simBrief.| **Route** | Your route will be blank unless you used our simBrief integration to build your flight plan, and you have the SimBrief plugin installed and SimBrief ID set in smartCARS 3 settings |
| **Cruise Altitude** | Cruise is automated in smartCARS 3, it will detect when you are in this phase and adjust if you should have to conduct step climbs or descents. |
| **Load** | Every pilot briefing is given a random load based on a couple variables. You can see this load by visiting your pilot briefing and looking at the left side. If you use our simBrief integration to generate your flight plan, it will use the load provided by our website or a custom load you enter. [Read more here.](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/books/3-help/page/simbrief) |
*Using our simBrief integration (**[read more here](https://docs.walkerair.us/books/3-help/page/simbrief "simBrief")**) will ensure that your **route** and **load** are prepopulated for your flight.*
**Notice about Online Networks** Do **not** select an online network in the *“Online Network”* dropdown within smartCARS3. We do not use ACARS data to determine whether you are flying on an ATC network. To appear on our maps and have your PIREPs correctly reflect the network, you must configure your Network ID(s) in your pilot profile. [***Click here to read how to add your ID(s) to your pilot profile.***](https://docs.walkerair.us/books/2-training/page/pilot-profile-settings-my-information "Pilot Profile – Settings > My Information") [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425648719.gif) Using the [](https://web.archive.org/web/20241119071819/https://docs.walkerair.us/uploads/images/gallery/2023-07/image-1688300396124.png) button here will also delete your bid in our CrewOps. --- ##### **Flight Tracking** Spawning in the correct origin airport will bring you to the Flight Tracking page. In this page, you can monitor your flight log for any erroneous logs. In this page, you can also change your route (by clicking the Show Route) and add comments (by typing into comment field then pressing enter) to the flight log in realtime as needed. You can find these options by opening the flight log as above. Pause at TOD is now the toggle button at the bottom left of the screen, under the comment field. There is also a drop down that will allow you to change your online network status while in flight. If you are on VATSIM or any other online service and accidentally forget to specify that at the start of your flight, you can now do it while in flight.*Your TOD is a rough approximation by the application based on your altitude and thus will not exactly match the TOD on your aircraft's ND and may, in certain cases, be after your FMS-calculated TOD.*
--- ##### **Flight Completion & PIREP Submission** After landing at your destination, taxi to the ramp, and come to a complete stop. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741453582626.png) Once stopped, a Submit PIREP button will show on the lower right hand, which once you hit, will send your PIREP to the Walker system. Once it is processed, a confirmatory notification on the bottom right will show up. If you have smartCARS premium, it will also notify that the logs have been sent to TFDi servers. You can also configure smartCARS 3 to autosend your PIREP through its settings. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741453606066.png)*If you didn’t exceed our flight requirements and/or standards, your PIREP will be automatically approved – and that will be verified by its presence in your **Logbook**.*
--- ##### **Flight Length Calculation** Veteran pilots who used smartCARS2 before may be confused with how total flight time is calculated in smartCARS 3 - unlike the previous version where it starts from pushback and ends only once the plane has reached a complete stop, the current version calculates total flight time using off blocks to in blocks. --- ##### **Map Tab** The Map referenced here is **not** the same one on the Crew Ops website. This shows various densities depending on your filter selection on the top right - ranging from VA-only to online networks. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425839831.png) --- ##### **Logbook** This page allows you to see your previous logged flights with the VA, and its PIREP status. You can also use the search and filter options if you are looking for a certain flight. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425858541.png) You can click on a flight to see more details, including the flight log, map, route, etc. [](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425868949.png)*We highly recommend using the Walker CrewOps [Logbook](https://docs.walkerair.us/books/2-training/page/pilot-profile-logbook) instead of the smartCARS one as that provides more detailed information. Further, flights logged with SC2 will not show all details in the SC3 viewer - particularly actual route flown on the map.*
--- ##### **Plugins** In this page, you may add community-built plugins to enhance your smartCARS user experience. As of now, there are no Walker-specific plugins added, nor are there any aside from the default ones that you will need to be able to fly for Walker.*Do note that the available SimBrief plugin in SC3 does not communicate with the Walker website - which means your passenger counts, routes, etc will not automatically sync on the CrewOps OFP page. We highly suggest using Walker's own SimBrief integration available on the CrewOps site, and we will not be liable for any PIREP inaccuracies or rejections resulting from the usage of the SC3 SimBrief plugin.*
[](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1741425886164.png) --- ##### **Settings** smartCARS 3 has a number of settings that you may adjust as you see fit and to align with your preferences - none of these settings should stop you from being able to log flights with Walker **aside from tracking provider**, so set them as you'd like.*We recommend that "Automatic PIREP submission" be disabled -- this will result in invalid flights being submitted to Walker that will be automatically rejected.*
[](https://docs.walkerair.us/uploads/images/gallery/2025-03/image-1743375621013.png) --- ##### **Reconnecting via SmartCars3** If your simulator crashes, but your SmartCars does not, you may attempt a reconnect following below steps. 1\. SmartCars will tell you the information about your aircraft prior to the crash - please match this as closely as possible and meet the requirement for reconnection (within 5nm and 2000ft of last recorded position). Do **NOT** click on [](https://docs.walkerair.us/uploads/images/gallery/2025-08/image-1754049780378.png) as that will be a rejected flight since you did not arrive at destination. [](https://docs.walkerair.us/uploads/images/gallery/2025-08/image-1754049749325.png) 2\. Once within the requirement for reconnection, a green button will show up beside [](https://docs.walkerair.us/uploads/images/gallery/2025-08/image-1754049780378.png) - called [. Click this button to reconnect.](https://docs.walkerair.us/uploads/images/gallery/2025-08/image-1754050266806.png) [](https://docs.walkerair.us/uploads/images/gallery/2025-08/image-1754050231712.png) 3\. Your log should then show *"flight tracking reconnected."* [](https://docs.walkerair.us/uploads/images/gallery/2025-08/image-1754050421248.png) 4\. Once reconnected, confirm with the SmartCars3 moving map and the Walker CrewOps map that you have indeed reconnected, which can be confirmed by seeing your aircraft moving on both maps. If you are not, Alt+F4 the sim and attempt the process again. # Stratos | Windows, PC, Mac OS, and Linux*If you haven't already read the [Flight Operations](https://docs.walkerair.us/books/3-help/chapter/flight-operations "Flight Operations") chapter, we recommend you do so now before continuing.*

[](https://docs.walkerair.us/uploads/images/gallery/2026-05/DFWimage.png) --- ##### **Pilot Dashboard** The Pilot Dashboard is the main home screen of Stratos and provides a quick overview of your Walker Air activity. From here, you can view important notices from the team, recent NOTAMs, your current rank progression, pilot statistics, and quick-access links to CrewOps, bids, Discord, support, and documentation. This page is designed to keep key information and tools easily accessible before and during your flight operations.*For a new, first time Pilot, these fields will be blank because no flights have been completed.*
To navigate through the remaining sections within *Stratos*, click the icons in the left column. You can drag these icons around as well to create your preferred menu layout. [](https://docs.walkerair.us/uploads/images/gallery/2026-05/qtHimage.png) --- ##### **Flight Bookings** The Flight Tracking page is where you select and monitor your active flight booking. Once connected to your simulator, click on a booking to expand it and reveal the **Start Tracking** button. Clicking **Start Tracking** will begin recording your flight automatically. Stratos will track your flight data in real time and submit your PIREP automatically upon completion. This page also provides a quick overview of your route, aircraft, distance, and estimated flight time before departure. [](https://docs.walkerair.us/uploads/images/gallery/2026-05/fLNimage.png) --- ##### **Walker Air Transport Validation System** The following validation checks are specific to Walker Air Transport and are designed to help prevent invalid PIREPs, reduce tracking issues, and ensure compliance with Walker Air policies before a flight begins. **Aircraft Validation** Verifies that the aircraft loaded in your simulator matches the aircraft assigned to your bid. **Event Validation** Checks that you are using an approved Walker Air livery when flying an official event. **Livery Validation** Checks that you are using a valid Walker Air livery when required. Please pay close attention to the following simulator values: - Aircraft ICAO - Aircraft Type - Livery These fields are critical for validation. If any of them display as **(Blank)** or do not match your bid requirements, validation will fail and should be corrected before tracking begins. If an issue is detected, Stratos will display a warning and allow you to either: - Correct the issue and click **Re-validate Simulator** - Continue by clicking **Start Tracking Anyway** ⚠️ Selecting **Start Tracking Anyway** does not bypass Walker Air policies or validation requirements. Flights that do not meet requirements may still be automatically rejected by our systems. These warnings are provided to help identify issues before your flight begins. [](https://docs.walkerair.us/uploads/images/gallery/2026-05/1iHimage.png) --- ##### **Flight Tracking** If you successfully pass the Walker Air Transport Validation System, you will be taken to the active Flight Tracking screen. This is where Stratos records your flight in real time from boarding to shutdown. The main map displays your live aircraft position and flight path, while the top status bar provides important flight information including altitude, speed, heading, ground speed, block time, and remaining distance. The right-side Flight Log records major flight events as they occur, such as boarding, engine start, taxi, takeoff, cruise, descent, and landing. Additional controls allow you to pause tracking, pause Top of Descent calculations, submit your PIREP, or cancel the flight if needed. The bottom-right panel also displays your current flight phase, next waypoint, and estimated arrival information. This screen serves as the primary real-time tracking interface throughout your flight. [](https://docs.walkerair.us/uploads/images/gallery/2026-05/nawimage.png) --- ##### **Flight Tracking - Top of Descent Pause** The **Pause at TOD** feature allows Stratos to automatically pause your simulator before reaching Top of Descent (TOD). This is useful for long-haul flights, overnight flights, or situations where you may step away from your computer and want additional time to prepare for descent and arrival. **Auto Mode** In **Auto** mode, Stratos uses your SimBrief flight plan data to automatically determine the Top of Descent point. You can configure how many nautical miles before TOD the simulator should pause. In the example shown, Stratos will automatically pause the simulator **5 nm before the SimBrief-planned TOD**. **Manual Mode** In **Manual** mode, you manually enter the remaining distance to destination where you want the simulator to pause. This uses straight-line distance to the arrival airport and should generally match the TOD shown in your aircraft FMS or flight planning software. Once the configured distance is reached, Stratos will automatically pause the simulator, allowing you time to return and prepare for descent procedures.| [](https://docs.walkerair.us/uploads/images/gallery/2026-05/stratos-gclozo23tw.png) | [](https://docs.walkerair.us/uploads/images/gallery/2026-05/stratos-5yacfemz0h.png) |

*If you didn’t exceed our flight requirements and/or standards, your PIREP will be automatically approved – and that will be verified by its presence in your **Logbook**.*
--- ##### **Logbook** The Logbook page provides a complete history of your flights flown through Walker Air Transport. At the top of the page, you’ll find overall pilot statistics including total flights, hours flown, total distance, average landing rate, and current rank. Below that is a detailed list of your PIREPs showing route information, aircraft used, flight duration, landing rate, points earned, and flight status. Flights can be filtered by status such as Accepted, Crashed, Diverted, or Rejected, and the search bar allows you to quickly locate specific flights. This page serves as your personal flight history and performance tracker within Stratos. [](https://docs.walkerair.us/uploads/images/gallery/2026-05/i23image.png) The detailed Logbook view provides a full replay and breakdown of an individual flight. The interactive map displays your recorded flight path from departure to arrival, while the activity log on the right shows a timeline of key events such as boarding, engine start, taxi, takeoff, cruise, pauses, and landing information. At the top of the page, you can quickly view important flight statistics including duration, distance flown, landing rate, and final PIREP status. The vertical profile graph displays your altitude changes throughout the flight, allowing you to review your climb, cruise, and descent performance. This page is designed to give pilots a complete post-flight review and analysis experience. [](https://docs.walkerair.us/uploads/images/gallery/2026-05/ks4image.png) --- ##### **Support Centre** The Support Centre allows you to create and manage support tickets directly within Stratos.
