Requirements:

To use this flight simulator, you need a WebGL 2.0 compatible web browser. You can test this here https://webglreport.com/?v=2 If you browser is not WebGL 2.0 compatible, please try to update it.
If you want to play using a joystick, you will need a GamePad API compliant browser (test it here) (Chrome, Firefox, Opera, etc.).

Satellite Images:

GeoFS is providing 10–60 meter global Sentinel-2 satellite images for free.
When flying with this dataset, the resolution is not sufficient to clearly render runways so GeoFS overlay a standard runway image for all the world major airports.

For a photo-realistic rendering, you can purchase HD (sub-meter) Microsoft Bing Maps imagery subscription for €9.99 per year
More about GeoFS HD on the GeoFS HD Subscriptions page).

How to control the flight simulator?

Option bar

The option bar, at the bottom of the game screen, is the main way to interact with the flight simulator:

• The first three menus are used to choose your aircraft, location and camera mode.
• The "options" button opens the configuration panel: configure controls, enable multiplayer/chat, weather preferences, etc.
• The "nav" button opens the navigation panel that contains the map and autopilot interface.
• The "pause", "mute", "reset" and "replay" buttons respectively pause the game, mute the sound, reset your flight to the last state and open the flight record player.
• Recorded flight player will replay up to 10 hours of flight while maintaining access to camera change and offering to locally save and/or load a saved flight.

Keyboard:

Configurable:

• Arrows up & down: tilt the aircraft
• Arrow left & right: roll the aircraft (mixed with yaw by default but can be configured)
• Enter recenter keyboard control input
• < & >: steer the aircraft (Yaw) (only effective when roll/yaw mixing is disabled)
• + & - (or PgUp & PgDn): Increase or decrease throttle. Press - again when idling to engage reverse when available
• [: lower the flaps one step (when available)
• ]: raise the flaps one step (when available)
• F: Cycle flaps one step at a time (when available)
• Home/End: increase/decrease elevator trim
• Delete: Reset elevator trim
• G: raise or lower the landing gear (when available)
• B: extend/retract air-brakes (when available)
• E: start/stop engine
• Space: brakes
• ;: Engage/Disengage parking brake
• X: Optional animated parts toggle
• Z: Accessories toggle (floats, water rudders, tailhook)
• You can configure the keyboard sensitivity from the "option" panel.

Fixed:

• 0 to 9: Directly set throttle by 10% steps
• A: Toggle autopilot
• C: cycle camera mode
• CTRL + Q: toggle orbit camera (in follow or cockpit mode)
• CTRL + W: toggle orbit camera vertically (in follow or cockpit mode)
• N: open navigation panel (map)
• O: open option panel
• Tab: fly to camera location (in free camera mode)
• P: Pause the simulation
• S: mute/unmute sound
• V: open replay mode
• K: set controls mode to "Keyboard"
• M: set controls mode to "Mouse"
• J: set controls mode to "Joystick"
• H: to hide/show the HUD (indicators)

Mouse:

• Mouse acts as a Joystick
• Press M to temporarily disable the mouse (while navigating menus and options). Press M again to re-enable mouse control.
• push/pull for tilt (or use the reverse option in configuration panel)
• left/right for roll (mixed with yaw by default but can be configured)
• You can configure the mouse (sensitivity, exponential) from the "option" panel.
• All other keyboard controls (except for arrows) are the same

Joystick:

Note: see how to enable the joystick.

• Joystick axis and button are by set by default
• If available, yaw is set on twist axis
• You can reconfigure every axis and buttons of the joystick from the "option" panel.
• All other keyboard controls are the same

Flying helicopters:

Helicopters are by definition much more difficult to fly than airplanes. The basic principle is to play with collective pitch (going up and down), cyclic pitch (going forward, backward, right and left) and anti-torque control (rotation/yaw).
By default, mouse and keyboard controls are mixing roll and yaw (aileron and rudder). This has to be disabled (in configuration panel) in order to properly fly the helicopter.
Ideally, you would have to use a joystick to be accurate enough with the helicopter but the mouse should be enough for a start.
In GeoFS, the collective pitch is controlled using the same input as the throttle for airplanes: if you press '+' several times, the helicopter will lift-off, if you press '-' it will go down.
Cyclic pitch can be controlled using the arrow keys or the mouse.
When roll/yaw mixing is disabled, use the rudder keys (default are keys < & >) for the anti-torque (yaw).
The rest is just practice and finesse.
For an in-depth introduction to helicopter flight, please refer to this great series of article from Helisimmer.com

Flying Major Tom:

Major Tom is probably the easiest and most relaxing way of flying in GeoFS. With just two keys you can take to the skies and look down at the earth.
The 'down' arrow key (or moving mouse or joystick up) fires the burner and when air is hot enough the balloon will take-off.
To navigate, you can try to climb to different altitudes and reach different direction and speed of wind.

Camera:

Six camera modes are available. You can choose between these from the option bar or by pressing "C" to cycle through all modes.

• Follow: the camera follows the plane at a distance using smooth transitions and no roll angle.
• Cockpit: the camera gives a view from the pilot seat.
• Cockpit-less: same as "cockpit" but without visible 3D model.
• Chase: the camera is static but look at the plane.
• Free: this is the default CesiumJS camera (uses default controls).
• Fixed: camera is attached to the aircraft but can be rotated and re-positioned

In "Follow", "Cockpit" and "Fixed" mode:

• left-click and drag your mouse to change the camera orientation.
• right-click and drag to set camera distance from the aircraft/cockpit.
• press and hold [Control] + right-click and drag to set camera horizontal and vertical position from the aircraft/cockpit.

In "Follow" mode, you can right-click and drag to set the camera's zoom factor/distance.
It is also possible to use the numerical keypad to set camera position around the aircraft.
Use mouse wheel to increase or decrease camera field of view. When in "Free" mode, you can position the camera to a location you like and press <Tab> to place the aircraft where the camera is.
Some aircraft will add extra cameras to the menu (cabin, wheels, wing, etc...)

Where can I fly?

Virtually everywhere!

• You can pick a preset destination from the option bar.
• The location selector also offer a search input field in which you can type any destination. The aircraft will be positioned at the chosen place and at an altitude of 1000 feet.
• The last (and best?) way is to use the in-game map to fly from over 30,000 runways in the world or anywhere else you may choose.

How to use the map?

See the standalone live GeoFS map

• Open the map using the "Nav" button (or press N) in the option bar.
• Every coloured dot marks a runway threshold. You can click on these dots to open an info balloon in which you can see three icons to "take-off from", "fly by" and "Approach" the clicked runway. When choosing "take-off from", the aircraft should be positioned on the threshold and facing the runway. Clicking on the "Approach" icon will set you on short final to the runway.note: due to some imprecision in the collected data, this is not always true (especially for small airfields).
• Dots are colour coded depending on the length of the runway: blue for major runways (>3,000 ft), yellow for smaller airfields.
• Runways equiped with ILS will offer an extra button to tune NAV1 to the ILS frequency
• A right-click on the map will bring a window to fly to the clicked destination from 6 pre-set altitudes and a button to create a GPS FIX.
• Navaids (VOR, NDB, DME, ILS) are plotted using the standard charts symbols. Clicking these icons will bring a popup with ident information (Type, name, ICAO and morse code) and a button to tune NAV or ADF to the correct frequency.
• The map also shows airspace areas. While this can be useful to practice some flight patterns, these data are to be used with this game only and should not be used for real life flying.
• Other players are shown as dark blue aircraft. Smaller, light blue aircraft icons represent ADS-B (real-life commercial) traffic around your current location.
• When enabled, the currently recorded flight path will be shown on the map with a colour changing with altitude. (green/blue/red from low to high)

Radio Navigation

• Navaids (VOR, NDB, DME, ILS) are shown on the navigation map using standard aeronautical charts icons.
• Clicking these icons will bring a popup describing the navaid (Type, name, ICAO and morse code) and two buttons to fly over or tune in to the frequency.
• VOR and ILS will tune into the NAV1 channels and will be used with HSI, CDI and ILS instruments when fitted to the aircraft.
• NDB will tune into the ADF channel and will be used with RMI (radio-compass) instruments when fitted to the aircraft.
• Alternatively, right-clicking anywhere on the navigation map will bring in the direct location popup which includes a button to create a GPS FIX.
• Creating a GPS FIX will add an icon to the map, replace the NAV frequency in the radio stack and set the OBS to a direct course toward the FIX.
• GPS FIX function similarly to a VOR with an infinite range.
• Clicking the map's FIX icon will bring a popup to delete, fly over or select the FIX.
• It is further possible to switch between the GPS FIX and the remembered NAV frequency in the radio stack.
• When tuning in from a navaid icon, the radio panel will open and show frequency and other information depending on the type of navaid
• It is also possible to open the radio panel by clicking on the "RADIO" button on the right hand side of the screen and tune in a NAV or ADF frequency directly.
• Pressing the "ident" button next to NAV and ADF frequencies will let you hear the morse code itentification for the tuned in station (if in range).
• When tuned in to an ILS, the localizer and glide slope are active on available instruments (HSI, PFD). OBS is meaningless for ILS approaches as course is automatically set to runway heading.
• When tuned in to an ILS, the NAV button of the autopilot will be enabled. When active, the autopilot will intercept and follow the localizer and glide slope to the runway
• When tuned in a VOR the course deviation will be active on available instruments HSI, CDI according to the selected radial (set with the OBS button)
• When tuned in a VOR, RMI (when fitted to aircraft) will use the station as a beacon and point to it (just like a NDB)
• When tuned in a VOR or having selected a GPS FIX, the NAV button of the autopilot will be enabled. When active, the autopilot will intercept and follow the specified radial (OBS) to or from the station
• When DME signal is available, according information will be shown in the radio panel or on PFD (Distance in nautic miles, ground speed toward station and time to station
• A well made video to explain how to use radio-navigation in GeoFS

Flight Plan

• Flight Plan UI is accessible from the navigation map panel
• When opened, the flight plan UI will add extra buttons to Navaids, GPS Fixes and Runway popups on the map
• These buttons can be used to add any of those locations as waypoints to your flight plan
• Runways can only be added as departure or destination
• Navaids can also be added by entering ICAO into the search box. If several choices are available they will be shown in a drop down box, sorted by distance from current location
• Latitude, longitude coordinates (decimal, separated by a coma ie: 52.368408,4.894413) can be entered in the same input box and added as a FIX waypoint to the flight plan.
• Each added waypoint generates a new leg in the flight plan and will show the distance (DST) to previous waypoint and tracking (TRK) course to the next waypoint
• Altitude (ALT) and speed (SPD) to be reached can be specified for each waypoint. Altitude is in feet by default of flight level when prefixed with FL, speed is in knots by default or as Mach number when prefixed with M
• At the end of the row, buttons allow for selecting (check mark) a waypoint, moving direcctly (double arrows) to the waypoint, reorder and delete the waypoint
• When autopilot is on and nav mode is selected, it will fly to each waypoint in a sequence
• If ILS is available to the destination runway, autopilot will automatically fly the ILS approach
• DME information (distance, ground speed and time to next waypoint) are shown in the radio stack where each waypoint is automatically being tuned in sequence when flying a flight plan
• Flight plans can copied and pasted and/or saved and loaded using the fours icons at the bottom right. GeoFS generates its own format as JSON files but will also accept external flight plan sources. Only flightplandatabase.com JSON export is currently supported but more should follow and/or will hopefully adopt GeoFS format.
