MeridianSim Ops

A map that runs on your PC. Your airplane from the sim, other airplanes, the weather, and the oceanic tracks, in one window. This page is only the download.

Version 0.12.169-beta · free download · Pro is $7 a month

North Atlantic tracks on the Meridian map
North Atlantic tracks, with the flights that are on them.
The airportSatellite, close enough to see the stands
Your airplaneMSFS, X-Plane, or Prepar3D, for the whole flight
TrafficLive, VATSIM, IVAO, and PilotEdge, each on its own switch
WeatherRadar, wind, and satellite on the same map

What it does

One window for the flight.

Airport
Live radar
Elevation tint
Heathrow satellite with live and network traffic

Airport

Your airplane, on the airport, with the other traffic.

Zoom in until the stands are visible. Live traffic, VATSIM, and IVAO can all be on the same field. If the sim is running, your airplane is there too.

  • Each network has its own on/off switch
  • You can filter by size, per network
  • Pausing the sim does not remove your airplane
Satellite over the city with occupancy and an imported flight

Map

Streets, or satellite.

Light or dark map. Satellite when you want the pavement. A route you loaded stays put while you move around.

  • Satellite is for the airport
  • The track letters still show who is on them
  • Zooming in does not clear the route
South Atlantic tracks over the ocean

South Atlantic

South Atlantic tracks, as published.

Same list as the North Atlantic. Click a route, copy the waypoints, and see who is already on it.

  • Both directions, when they publish both
  • All oceans at once, or just this one
  • Last cycle is dashed. The next cycle is dash-dot
Pacific organised tracks with traffic

Pacific

Pacific tracks are in the same list.

NOPAC and PACOTS when they publish them, and the West Atlantic routes. Numbered routes sit next to the Atlantic letters.

  • Click a route to copy it and see who is on it
  • Previous and next cycles look different from the current one
  • The oceans people actually fly are in one window
A crossing brief New York to London

Crossing

New York to London, ready to copy.

Build a crossing and you get a published track, the levels, the route that joins it, and a string you can paste into the sim or SimBrief.

  • Works for a short hop and for an ocean crossing
  • Copy the route into SimBrief or the sim
  • If a flight files a track, the line follows that track
Types catalog with airframe photographs

Aircraft

Pick a type. See who is flying it now.

The catalog runs from an A380 to a light aircraft. Filter by size, or type the name. Open one and you see who is airborne in it.

  • Photos in the catalog and on each flight
  • The type code or the name both work
  • Opening one flight does not clear the map
NAT occupancy: letters across the top, flights listed under a track

Tracks

Who is on the track.

The letters are the tracks. The number is how many airplanes are on that track right now. Live, VATSIM, and IVAO are counted separately. Click a letter for the callsign, the type, and the route they filed.

  • Click a letter to see the names
  • Live, VATSIM, and IVAO stay separate
  • The filed route is in the list
VATSIM airspace polygons over Europe

VATSIM airspace

VATSIM airspace uses the real boundaries.

Centers and approach use published shapes, not circles. On the airport, D, G, T, and A are delivery, ground, tower, and ATIS.

  • Turn positions on or off in Display
  • The station card shows the controller, time online, and the ATIS
  • Audio stays in the side rail after you sign in on VATSIM’s page
SID and STAR geometry on a filed route

Procedures

The route follows the SID, not a straight line.

A pasted route or a SimBrief plan is drawn along the waypoints and airways, including the SID and STAR that were filed. It is not a straight line between the two airports.

  • One filed transition, not every transition in the book
  • A looked-up flight and an imported plan can both be on the map
  • Clear the imported plan when you are done
An FAA STAR plate open in Meridian

Charts

The plate, when you need it.

US FAA plates. Open one, mark it up, close it. The map is still there. US only. This is not Navigraph.

  • SID, STAR, approach, taxi, and minima
  • The current cycle is stamped on the plate
  • Not for navigation
