A serious mobile flight sim with 60+ aircraft, 1900+ HD airports, satellite terrain, and live global air traffic. The mod build is the same simulation, just with the paid content already open.
What is RFS - Real Flight Simulator
RFS - Real Flight Simulator is a flight sim from RORTOS, an Italian studio that builds detailed aviation games. You take off from real airports, fly over satellite-mapped terrain, and run proper pilot procedures from pushback to touchdown. It leans much closer to a study sim than an arcade plane game, which is a big part of why it has passed 5 million installs on Google Play.
The aircraft list runs from commercial airliners to cargo freighters to military jets. Each one has a 3D cockpit, a working flight management computer, and realistic lighting. You can plan long-haul routes with autopilot, VNAV, LNAV, and ILS landing assistance, then fly them with live weather and a real elevation model under the wings. The 1900+ HD airports come with jetways, taxiway markings, and ground services like refueling and catering.
The base game is free with ads. A paid layer adds the full aircraft fleet, multiplayer, and extra airports, and that paid layer is what mod builds go after. Search "rfs mod apk" on sites like apkpure or happymod and most results point at variants that unlock the same content. That is exactly what the build on this page does.

What this mod offers
The community build of RFS - Real Flight Simulator 3.1.9 opens up the paid content the free version keeps behind a purchase. The flight model, terrain engine, airport set, and cockpit detail match the Google Play release exactly. Here is what the mod typically changes, plainly stated:
- Full aircraft fleet unlocked.
The premium airliners, cargo freighters, and military jets are available without the in-app purchase. You fly the plane you actually want from the first session.
- Premium airports included.
The extra detailed HD airports that the paid version adds are opened up too, which widens your choice of realistic departure and arrival points.
- Multiplayer access opened.
Real-time multiplayer, normally locked behind the paid tier, is reachable, so you can share airspace with other pilots.
- Liveries and add-ons available.
Aircraft liveries and cosmetic add-ons from the paid shop are unlocked across the fleet so you can try them out.
- Reduced ad interruptions.
The ad load from the free build is trimmed back. That keeps your attention on planning and flying instead of waiting through interstitials between sessions.
- Same core simulation.
Autopilot, FMC, ILS approaches, checklists, and live weather all behave the way they do in the official app. The mod opens content. It does not rewrite the sim.
