Installation

Below are concise steps for Windows, macOS, and Linux.

Windows

1. Download the latest installer from the FlightGear website.
2. Run the installer and follow prompts (choose “Full” if unsure).
3. After installation, run the FlightGear Launcher.

macOS

1. Download the macOS DMG or installer package.
2. Open the DMG and drag FlightGear to Applications.
3. Gatekeeper: if macOS blocks the app, Control-click > Open.
4. Run the FlightGear Launcher from Applications.

Linux (Ubuntu/Debian-based)

1. Use the distribution packages for a quick install: sudo apt update sudo apt install flightgear fgfs
2. For the latest version, consider using the official PPA or building from source.
3. Run flightgear or FlightGear Launcher from the application menu.

Essential launcher settings

When you first open the FlightGear Launcher, configure these items:

• Aircraft: select a simple, well-documented aircraft (e.g., Cessna 172SP).
• Location: pick a nearby airport or famous landmark for easier visual navigation.
• Weather: choose “Fair” or “Clear” for the first flight to reduce difficulty.
• Time: set daytime to better see landmarks and runways.
• Scenery: enable TerraSync to download current scenery automatically (recommended).
• Controls: configure joystick or keyboard. Calibrate axes and assign throttle, rudder, and flaps.

Choosing your first aircraft

Start with a stable, forgiving general aviation aircraft:

• Cessna 172SP — ideal for learning basic flight: takeoff, cruise, and landing.
• Piper PA-28 — another trainer-type aircraft with documenation. Avoid complex airliners or gliders for your first session.

Basic controls and instruments

Controls to set and learn first:

• Aileron (roll) — usually joystick X axis / keyboard A & D.
• Elevator (pitch) — joystick Y axis / keyboard W & S.
• Rudder — twist axis or pedals / keyboard Q & E.
• Throttle — slider or axis / keyboard F (increase) and V (decrease).
• Flaps — increment/decrement keys (commonly comma and period).
• Brakes — toe brakes or keyboard (space for parking brake).

Important instruments:

• Airspeed Indicator (KIAS/KTAS)
• Altimeter
• Attitude Indicator (artificial horizon)
• Heading Indicator/Compass
• Vertical Speed Indicator

Preflight checklist (basic)

1. Master switch ON (electrics)
2. Avionics ON (if applicable)
3. Fuel pump and mixture set (for piston engines)
4. Controls free and correct
5. Trim set for takeoff
6. Flaps set for takeoff (usually 0–10° for Cessna)
7. Parking brake released
8. Runway heading selected

---

Startup and taxi

1. Start the engine using the launcher-control or ignition key for the chosen aircraft.
2. Check gauges: oil pressure, RPM, electrical systems.
3. Release parking brake, taxi at low speed to runway using rudder and brakes.
4. Use external view sparingly — cockpit view helps you monitor instruments.

---

Takeoff procedure (Cessna 172 example)

1. Align with runway centerline.
2. Apply full throttle smoothly.
3. Maintain centerline with rudder.
4. At ~55–60 KIAS, gently pull back on the yoke to lift off.
5. Climb at 70–80 KIAS; retract flaps gradually once positive rate established.
6. Trim for climb to reduce control forces.

---

Basic flight maneuvers

• Straight-and-level: trim to maintain altitude and heading with minimal control input.
• Turns: bank gently 10–20° for standard rate turns; maintain altitude with pitch.
• Climb & descent: adjust throttle and pitch; monitor vertical speed indicator.
• Cruise: set throttle and trim; monitor engine temps and mixture as appropriate.

---

Approaching and landing

1. Choose an airport with a long, clear runway for your first landing.
2. Enter the traffic pattern: downwind, base, final.
3. On base, reduce power and extend flaps as appropriate.
4. On final, set approach speed (e.g., 60–70 KIAS for Cessna 172).
5. Flare just before touchdown: reduce throttle, slowly raise nose to reduce descent rate.
6. Apply brakes gently after touchdown; use spoilers or ground roll technique if available.
7. Exit runway and perform after-landing checklist (flaps up, lights as needed).

Troubleshooting common issues

• Poor performance or lag: lower graphics settings, reduce scenery detail, enable texture compression.
• Controls not responding: check joystick calibration and key bindings in the launcher.
• Missing scenery: enable TerraSync or download additional scenery packages.
• Strange flight behavior: verify aircraft model settings and update FlightGear to latest release.

---

Useful tips & addons

• Use TerraSync to get up-to-date scenery automatically.
• Install OMSI or add-on aircraft from FlightGear forums for more variety.
• Use external panels or instruments (like OpenPanel) for advanced cockpit setups.
• Join the FlightGear community (mailing lists, forums, Discord) for help and aircraft/scenery sharing.
• Practice short flights and landings frequently — skills improve fastest with repetition.

---

Resources for learning

• FlightGear Wiki (comprehensive docs on aircraft, controls, and configuration).
• YouTube tutorials for visual walkthroughs (search for Cessna 172 FlightGear tutorials).
• FlightGear forums and community channels for troubleshooting and add-ons.

Start with short sessions, keep settings simple, and gradually add realism (advanced weather, failures, complex aircraft) as you gain confidence. Enjoy your first flights — FlightGear rewards curiosity and practice.
