Luftrum is a free persistent-world add-on for Microsoft Flight Simulator built around one idea: whatever you feel like flying should belong to the same coherent aviation world.
Luftrum combines open aviation, terrain, civil and economic data into one persistent model. At the commercial end that means real passenger airlines, cargo carriers, charter companies and VIP operators with real networks, fleets and aircraft identities down to individual tail numbers. Airports, populated places, geography and real-world organizations provide the context around them.
Airline, cargo, charter and VIP flying are not skins over the same generic job system. Each segment is modeled around the operators, aircraft, geography and operating patterns that make it distinct.
Fly real networks with real fleets and aircraft identities down to individual tail numbers, from island-hopping Twin Otters to A380 long-haul operations. Real-world rotations and repositioning flights make the work continue beyond a single leg.
Move freight from feeder C208s to the largest widebody freighters, mixing scheduled cargo networks with charter work instead of treating cargo as one generic mission type.
Passenger and cargo charter companies operate in their real-world regions, with demand tied into the wider world model instead of appearing as random airport-to-airport jobs.
Fly real VIP fleets alongside government, military and air-ambulance missions that use the organizations and aircraft that actually perform those roles.
Broad commercial GA flying does not exist in real life at the scale a flight-sim world needs. Instead of pretending it does, Luftrum procedurally builds a credible small-aircraft economy: flight clubs own aircraft, GA-scale operators create work, and NPC pilots keep jobs moving and fleets circulating even while you are offline.
Career and Open Sky share the same aviation world, but they answer two very different moods.
Start in the club world of GA flying, pass real checkrides, build certifications and experience, then enter carrier employment and work your way toward more demanding aircraft, operators and roles. Career progression is deliberately earned rather than fast-tracked.
Explore Career Onboarding →Open Sky is for the nights when you want a believable reason to fly without a career ladder. Pick real-world airline, cargo, charter or VIP work, enter employment on easy terms, or move around the living GA economy without grinding through certifications first.
Explore Open Sky Features →Luftrum scores how you fly, not just whether you arrive. Aircraft-aware scoring can evaluate the parts of a flight that are easy to ignore in a simple tracker — speed control, heading and altitude discipline, descent planning, approach stability, turn coordination, touchdown quality and more. The same scoring foundation powers checkrides and gives individual flights a meaningful record.
Adventure Flights are scenic and endurance tours inspired by the Bush Trips of MSFS 2020. Multi-leg routes take you through historically, geographically or culturally interesting places — or simply test your stamina — while Luftrum keeps the scoring, time tracking and friendly competition around the journey.
Browse Adventure Flights →Real operators, generated GA companies, NPC pilots, aircraft movement, employment, rotations, scoring, pilot history and community activity all live in the same shared system. The point is not to force one style of flying on everyone — it is to make almost any style of flying feel like it belongs somewhere.
