Importing Flight Plans into Aerofly FS 4 and FS Global

Aerofly FS 4 and Aerofly FS Global do not read .PLN or .FMS files the way Microsoft Flight Simulator and X-Plane do. NG ROUTE instead exports a custom mission file that Aerofly loads from a fixed filename in your user documents folder. Once you understand that one-time folder setup, loading IFR routes becomes straightforward.

What NG ROUTE exports for Aerofly

Click ↓ Aerofly FS 4 / FS Global after creating a plan. The download is always named:

custom_missions_user.tmc

Aerofly only reads custom missions from that exact filename. Do not rename it. Each new export from NG ROUTE overwrites the previous mission content in that file — back up an older mission copy if you want to keep multiple routes and swap files manually.

Where to put the file

Move custom_missions_user.tmc into the Aerofly user missions folder. Create the folder if it does not exist.

• Windows (Aerofly FS 4): Documents\Aerofly FS 4\missions\custom_missions_user.tmc
• Aerofly FS Global: equivalent path under Documents in the Aerofly Global user folder (name varies by install; check Aerofly documentation for your version).

Exact paths can differ if you changed the Windows Documents location or use a custom Aerofly user directory. The Aerofly wiki documents current folder layouts per platform.

Loading the mission in Aerofly

1. Start Aerofly FS 4 or FS Global.
2. Open Missions from the main menu.
3. Select Custom Missions.
4. Your NG ROUTE flight appears in the list with departure and destination information.
5. Choose the mission, select aircraft if prompted, and pick the runway in-sim.

Aerofly maps your NG ROUTE aircraft choice to the nearest available type in the sim. A requested A320 may appear as a similar Airbus model Aerofly ships natively.

Runways and procedures

NG ROUTE suggests runways from live METAR winds, but Aerofly requires you to confirm runway selection inside the sim. SIDs and STARs are not embedded in the mission file — fly the en-route portion from the mission and manage approach transitions manually.

Because Aerofly does not inject live METAR weather globally the way MSFS does, many pilots use standard pressure 1013 hPa (29.92 inHg) for cruise and approach per the NG ROUTE user guide. Real-world QNH from METAR is still useful for briefing even if the sim atmosphere stays standard.

NAVdata limitations

Aerofly's navigation database updates differently from X-Plane. Long international routes may include fixes that Aerofly does not recognize. Shorter European and US domestic legs within Aerofly's baked-in coverage work more reliably.

If a waypoint fails, note the next valid fix from the NG ROUTE nav log and continue the route visually or via autopilot heading mode until the mission path recovers.

Replacing missions

Because only one custom_missions_user.tmc is active at a time, build a new NG ROUTE plan whenever you want a different city pair. Some pilots keep archived copies:

• custom_missions_user_EGLL-EHAM.tmc as backup
• Copy the desired backup to custom_missions_user.tmc before launching Aerofly

Pre-flight checklist

1. Route built and exported from NG ROUTE
2. File placed in missions with correct name
3. Mission visible under Custom Missions
4. Runway selected to match METAR suggestion where possible
5. Fuel set from NG ROUTE totals in aircraft setup if available
