What is Turnline?

More than flying. The entire operation.

A real airline flight doesn’t start when the engines do. Long before pushback, a dispatcher has planned the route and fuel, ground crews are preparing the aircraft, passengers are boarding, and an operations team is watching the whole schedule.

Turnline is a next-generation airline operations simulation platform for Microsoft Flight Simulator, designed to connect flight planning, aircraft operations, passengers, ground handling, operational decisions, and postflight analysis into one cohesive experience.

Every flight has a plan. Every operation has moving parts. Every decision affects what happens next.

Flight dispatch

Plans the route, fuel and paperwork the flight is released with.

Pilots & aircraft

Fly the plan and handle what changes along the way. That’s you.

Ground services

Fuel, catering, baggage and pushback at the gate.

Passengers & cabin

Boarding, cabin service and the people the flight is for.

Air traffic control

Clearances, slots and sequencing that shape the timeline.

Operations control

Keeps the schedule running and decides how to handle disruption.

Turnline connects them around one flight TURNLINE 247

How Turnline works

Six stages. One continuous flight.

Each stage hands something to the next: the plan sets expectations, preparation decides when you’re ready, what happens on departure shapes the rest of the flight, and the debrief explains why it went the way it did.

  1. Plan

    Planned

    Import a dispatch plan, review route and fuel information, and establish the operational baseline.

    Sets the schedule every later stage is measured against.

  2. Prepare

    Planned

    Manage gate readiness, aircraft preparation, passenger boarding, and ground-service milestones.

    Boarding and servicing progress decide when you’re ready.

  3. Depart

    In active development

    Track operational milestones and respond to delays or constraints.

    A late milestone moves the departure estimate.

  4. Operate

    In active development

    Monitor the flight and operational consequences as events unfold.

    Phases and events are recorded as they happen.

  5. Arrive

    In active development

    Manage arrival, turnaround completion, and final flight status.

    Arrival is compared with the plan; the flight closes out.

  6. Debrief

    In active development

    Understand performance, disruption causes, decisions, and overall operational results.

    Explains what happened, why, and what it led to.

Stage labels describe the experience as a whole. Today’s internal builds detect flight phases and record a flight timeline; dispatch import, turnaround workflows, delay handling and cause-based debriefs are planned. The Feature Explorer below lists each capability’s status.

Flight Dispatch & Planning

The plan the whole flight is measured against.

  • SimBrief integrationPlanned

    Bring an existing SimBrief plan into Turnline instead of re-entering it, using documented interfaces.

  • Operational flight plan informationPlanned

    Key plan details available alongside the flight, not buried in a separate document.

  • Scheduled & estimated timesPlanned

    Scheduled departure and arrival, with estimates that update as the operation changes.

  • Fuel & route informationPlanned

    Planned fuel and route as the baseline for decisions and the debrief.

  • Flight-release workflowPlanned

    A clear point where the flight is released and the operation begins.

Ground Operations & Turnarounds

Everything that has to happen at the gate before you can push.

  • Aircraft turnaround timelinePlanned

    Turnaround activities laid out against the departure time they feed.

  • Boarding & baggage milestonesPlanned

    Progress you can see, with late milestones flowing into departure readiness.

  • Catering & servicing conceptsPlanned

  • Pushback & departure readinessPlanned

    A single answer to “are we ready to go?” built from the milestones above.

  • GSX Pro interoperabilityResearch

    Investigating whether ground-service events can be reflected in the Turnline timeline. Not supported or endorsed today.

Passengers & Cabin

The people on board, and how the operation affects them.

  • Passenger manifest conceptsPlanned

    Who’s booked and who’s boarded, at a level that informs operational decisions.

  • Boarding progressPlanned

    Boarding that takes time, can run late, and affects departure.

  • Cabin-service coordinationPlanned

    Cabin activities placed on the same timeline as the flight.

  • Operational passenger impactPlanned

    Delays and decisions reflected in what passengers experience.

  • Passenger-experience modelingPlanned

    A longer-term model of how the operation shapes the passenger journey.

Live Flight Operations

What your aircraft is doing, recorded as part of the operation.

  • Simulator telemetryIn active development

    A simulator connection for MSFS 2020 and 2024. Built and tested against simulated data; validation with real MSFS is under way.

    Taxi, takeoff, climb, cruise, descent, approach, landing and taxi-in detected from aircraft state.

  • Operational milestonesImplemented internally

    Key moments such as departure, takeoff, landing and arrival captured on the flight’s timeline.

  • Disruption & delay modelingPlanned

    Events that create delays, and delays that carry consequences downstream.

  • Flight-event historyImplemented internally

    Events, interruptions and phase changes stored with the flight.

Aircraft & Third-Party Integrations

Working alongside the simulator and tools you already use.

  • SimBrief integrationPlanned

    Dispatch plan import, subject to the provider’s documented interfaces and terms.

Operational Debrief

Not just what happened: why, and what it led to.

  • Flight timelineImplemented internally

    A phase-by-phase timeline of each recorded flight.

  • Departure & arrival performancePlanned

    Actual times compared with the schedule the flight was planned against.

  • Delay classificationPlanned

    Delays attributed to causes such as boarding, servicing or air traffic.

  • Decision-based analysisPlanned

    The decisions you made and the consequences that followed.

  • Persistent flight recordsImplemented internally

    Flights stored locally on your PC, so your history doesn’t depend on a cloud account.

Why Turnline is different

One flight. One connected operation.

Turnline’s focus isn’t a longer feature list. It’s operational cause and effect: what happens in one part of the flight carrying through to the next.

A typical multi-tool flight today

Great tools, each running on its own clock.

  • Separate tools
  • Disconnected timelines
  • Independent events
  • Limited cross-system consequences

The connected operation Turnline is designed for

One timeline, where a late milestone moves everything after it.

  • Unified operational timeline
  • Events influencing downstream operations
  • Aircraft-aware workflows
  • Connected operational decisions
  • Meaningful postflight analysis

Designed to work alongside your add-ons, not replace them. Planning tools, ATC services, ground-handling add-ons and aircraft systems each do their job well. Turnline aims to sit across them and give the flight a single operational story.

A design goal, not a verdict. We’re describing what Turnline is being built to do. How well it delivers on that is for you to judge once you can try it.

Decisions have weight

Holding for passengers, accepting a late servicing slot or adding fuel each trade one outcome for another. Consequences make those choices mean something.

Delays have causes

A late departure tells you little on its own. Knowing it started with boarding at 14:12 tells you what to do differently.

The debrief tells the story

Connecting cause and effect turns a log of times into an account of how your operation actually ran.

Integration ecosystem

Built to connect your flight sim world.

Turnline is designed to complement the simulator and add-ons you already fly with. Here is where each potential connection stands today.

  • In active development

    Microsoft Flight Simulator 2024

    Target platform, validated separately from 2020. Compatibility validation is under way.

  • Planned

    SimBrief

    Planned dispatch-plan import using documented interfaces, subject to the provider’s terms.

  • Research

    SayIntentions

    Interoperability under investigation. Not a working integration or a partnership.

  • Research

    GSX Pro

    Ground-service interoperability under investigation. Not a working integration or a partnership.

  • Research

    Aircraft ACARS / AOC ecosystems

    Researching aircraft-specific messaging. Support would vary by aircraft and what it exposes.

Integration support depends on documented interfaces, each aircraft’s capabilities, and the permission of the provider involved. Some connections may prove impractical, and we’ll say so if they do. Statuses here are updated as work progresses; “Research” means we’re investigating, not that support is coming.

FAQ

Questions, answered honestly

Can’t find what you’re looking for? Email support@turnlineops.com.

What is Turnline?

Turnline is an airline operations simulation platform in development for Microsoft Flight Simulator. It aims to connect flight planning, ground handling, passengers, the live flight and the postflight debrief into one operation, so decisions and delays carry through the whole flight.

Is Turnline a flight tracker or an airline management game?

Neither, exactly. A flight tracker records where you flew; an airline management game usually has you run a company from a spreadsheet. Turnline focuses on the operation around each flight you actually fly: the plan, the preparation, what happens on the day, and the debrief.

Which flight simulators will Turnline support?

Turnline is being built for Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024 on Windows PCs. Compatibility with each simulator is being validated separately and isn’t confirmed yet for either.

Will Turnline work with SimBrief?

SimBrief import is planned. It isn’t available yet, and it will depend on the provider’s documented interfaces and terms. Turnline isn’t affiliated with Navigraph or SimBrief.

Will it work with SayIntentions and GSX?

Both are under investigation. There’s no working integration or partnership today, and we can’t promise one. Whether it’s possible depends on what each product exposes and on its developer’s permission.

Will aircraft ACARS systems be supported?

We’re researching it. ACARS/AOC features differ from aircraft to aircraft, so any support would be aircraft-specific and depend on what each aircraft makes available. No aircraft is supported today.

Can I use Turnline with my existing add-ons?

That’s the intent. Turnline is designed to run alongside your aircraft, planning tools, ATC and ground-handling add-ons rather than replace them. Specific compatibility will be confirmed through testing before we make any claims.

Is Turnline available now?

No. Turnline is in development and there’s no public download yet. Joining the early-access list is the best way to hear when that changes.

Will Turnline be free?

Pricing hasn’t been decided or announced. We won’t speculate until we can give you a straight answer.
