I purchased aerofly FS from the Mac App Store but the download doesn't finish, what can I do?
The delivery of the App to your computer is solely in the hands of Apple, so unfortunately there isn't much we can do. However if you cannot finish the
download you have the right to cancel your purchase and receive a refund.
Some customers however were able to fix this problem by doing the following:
  • Create a new temporary Mac OS X user account
  • Log into this new account and start the App Store application
  • Try to continue downloading the App using your existing iTunes account
  • Once the download is finished, log out again and log back in again with your usual user account
  • You may then delete your user account again

Can I use my Mac Book Air for aerofly FS?
No, aerofly FS does not work on the Mac Book Air.

aerofly FS runs extremly slow after changing the graphic settings, what can I do?
The graphic quality settings have a huge impact on the performance of aerofly FS. If you are using a graphic card with 512 MB or less do not set the Texture
qualities higher than Medium. If aerofly FS is impossible to use after changing the settings, you may have to reset the default settings. Have a look at the next
question on how to do this.

How do I reset the settings of aerofly FS?
All config files of aerofly FS are stored in a special folder inside your users Library folder. By default the Library folder of Max OS X 10.7( Lion ) and10.8 (
Mountain Lion ) is hidden. To open the Finder with a visible Library folder, press and hold the ALT Key, choose the "Go To" menu and then select "Library". A
Finder window with the Library folder will then be opened. On Mac OS X 10.6 the Library folder is visible by default.
Next click yourself to the aerofly FS user folder. The location depends on what Mac OS X version you are using and if you have purchased aerofly FS as a
boxed version or from the Mac App Store.

For aerofly FS from the Mac App Store and running Mac OS X 10.7 or 10.8:
    ~/Library/Containers/com.aerofly.aerofly-fs/Data/Library/Application Support/aerofly FS/

For the boxed version of aerofly FS or the Mac App Store version on Mac OS X 10.6:
    ~/Library/Application Support/aerofly FS/

In this folder simply remove all files inside the config folder.

How do I locate the log file tm.log of aerofly FS?
First locate the aerofly FS user folder, this is described in the previous question. The file tm.log is located right inside this folder.

Is TrackIR ( Head Tracking feature ) supported in the Mac version?
Currently there is no support for TrackIR in the Mac version of aerofly FS.

aerofly FS crashes when I connect the Playstation 3 controller.
There is a bug in aerofly FS that causes the program to crash whenever a Playstation 3 controller is connected to your Mac. Please disconnect the controller
before starting aerofly FS. This bug will be fixed in an upcoming update.

Does aerofly FS run in a virtual machine like VMWare or Parallels for Mac OS X?
aerofly FS cannot be used in a virtual machine. We offer dedicated versions of aerofly FS for Microsoft Windows and Mac OS X.
aerofly FS crashes right after program start, what can I do?
First ensure your PC really meets the minimum system requirements.

Most crashes are due to older graphic card drivers. It is strongly recommended that you update your 3D graphic card driver to the latest version before running
aerofly FS. Most computers have 3D drivers installed, but aerofly FS requires up to date drivers to work properly. Please don't use the Windows Update
function to search for a current driver, instead visit the 3D graphic card manufacturer for the latest version.
For NVIDIA and AMD graphic cards visit:

aerofly FS does not run smooth and my frame rate is below 30 FPS, what can I do?
First ensure your PC really meets the minimum system requirements.

If your 3D card meets our requirements carefully revise your graphic settings in aerofly FS. Setting the quality in aerofly FS too high has a big impact on the
performance. Even when using a 3D card with 1 GB of Ram it is not recommended to set all settings to High or Ultra, instead choose to use less texture
quality or terrain texture quality.
Do I need a joystick to fly aerofly FS?
A joystick is generally recommended for the best flying experience, however you can also use a game-pad, your mouse or even the keyboard. The mouse
option for steering is actually very precise and once you get used to it allows very good and smooth flying.

How many airports are in aerofly FS?
There are currently a total of 11 airports complete with buildings modelled. These airports are good VFR flying, like Samedan and Birrfeld. All other airports
have the runway modelled. So you can basically land on all available airports in Switzerland.

How current are the aerial images?
The images have been taken over a long period of time. So you will see areas with fairly new date, but there are also areas that are many years old and might
not feature all buildings or roads that exist today. However the overall quality of the aerial images no matter what date it was made is very high and results in an
impressive visual quality.

Can I set a different time of day or even night?
The scenery of aerofly FS is based on real aerial images made at a certain time of day and a certain time of the year. So the current version does not allow the
changing of time. We will consider this for a future update, since aerofly FS already features the ability to do real time lighting computations.

Is aerofly FS a simulator or more like an arcade game?
aerofly FS puts its focus on extremly realisitic flight physics. All aircraft flies extremly close to their real counterparts. So in this respect its not an arcade flight
simulator! Yet, aerofly Fs focuses on an intuitive user interface so one can concentrate fully on the flying side. There are no complicated setup procedures to
get the aircraft going, simply run aerofly FS and off you go!

Will there be Updates, Upgrade and AddOns for aerofly FS?
The development of aerofly FS will continue. We will publish new updates, upgrades and AddOns. However it is our philosophy to publish new material when its
really "done", so we won't make any announcements prior to a new release.

How does aerofly FS compare to other flight simulators?
aerofly FS puts its main focus on the flying side paired with awesome graphics, realistic physics and a fluent simulation speed. The operation of all aircraft is
kept very simple on purpose, so no setup has to be done inside an aircraft to start flying. Yet all basic instruments in the cockpit are animated and show real
If you are looking for exact aircraft operations like setting up navigational instruments or adjusting the motor then other simulators are better for you.

Do I have to be a pilot to master the aircraft in aerofly FS?
aerofly FS gives you a steep learning curve even if you are an absolute beginner. You don't need to focus on setting up an aircraft like turning on the engine, or
moving certain switches into the right position. You can fly right away. Using our challenges you get tasks with increasing difficulty depending on your personal
flying skills.

Can one fly outside the area of Switzerland?
aerofly FS is currently covering the whole area of Swityerland. However we have also modelled the outside areas like Germany, France and Italy with lower
resolutions images. So yes, you can fly outside of Switzerland, but with a reduced quality.
aerofly FS randomly shuts down on my iPad 2 / iPad Mini, what can I do?
aerofly FS requires quite a lot of resources and might hit a limit on the Apple iPad 2 or iPad Mini which feature "only" 512 MB of memory. The newer iPad 3
and 4 are equipped with twice the amount of memory.
To increase the amount of free memory, close all Apps that are open, you won't loose any data doing this step, its just used to free up memory:
    - From the Home screen, click the Home button twice.
    - Tap and hold on any app thats showing in the bar.
    - When it starts to jiggle, tap the  to close it.
    - Repeat this will all other Apps that are currenly open until no open App is left.
    - Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
    - Press and hold the Sleep/Wake button until the Apple logo appears.
    - Then try to run aerofly FS again

I can't hear any sound or there is no engine sound, what can I do?
Please carefully follow the steps below, after that you should have sound in aerofly FS again:
    - From the Home screen, click the Home button twice.
    - At the bottom you will then see a bar with active Apps.
    - Wipe your finger to the right.
    - Now check if the symbol for the loudspeaker is active and that the volume slider is high enough.
    - Additionally, please check if the silent button next to the volume rocker button is not set up to switch off the sound. If so, switch this button as well.

The Corsair sounds strange ( Constant speed propeller )
Airplanes like the Corsair are equipped with a constant speed propeller. The constant speed propeller is equipped with a governor, that adjusts the propeller
blade pitch to keep the propeller/engine rpm at the set value. Power output is controlled by the throttle and indicated by manifold pressure (in fixed pitch
airplanes engine rpm is the main indicator for power output, this obviously doesn't work for constant speed). If the throttle is opened / manifold pressure is
increased, the engine torque increases and rpm would also increase. The governor counteracts by increasing the propeller blade pitch. The rpm stays the
same, but the propeller now has more 'grip', and the higher engine torque is transformed to more thrust and increasing airspeed. If the engine power is reduced,
the rpm still stays the same, but the thrust is reduced and the airspeed decreases. This works as long as the governor can reduce the blade pitch. As soon as
the blades reach their pitch stops, the rpm will decrease if power is reduced further. This happens at low airspeed and on the ground, when the engine is at
idle. When flying an airplane equipped with a constant speed prop, rpm (and thus engine sound) is no longer an indication for power output, use the manifold
pressure instead.

Can you explain the flight information bar and how do I use the autopilot?

(1) Wind
Shows the current windspeed and direction with respect to the aircraft's orientation. This example shows a very light wind from the left.

(2) Heading indicator
Shows the current heading in degrees. The magenta trend indicator bar shows what the heading will be in 6 seconds at the current rate of turn. For a standard
turn rate of 180 degrees per minute the trend indicator has a length equivalent to 18 degrees.
The heading bug (the magenta symbol above the 'W' in this example) and magenta number to the left are displayed if a heading for autopilot operation is
selected (see below). 

(3) Airspeed indicator
Shows the IAS (indicated airspeed) in knots. The magenta trend indicator shows what the airspeed will be in 6 seconds. The color of the tape shows the
airspeeds for the current aircraft:
- green     normal range
- white     airspeed range with flaps extended
- yellow    operation in smooth air without abrupt control inputs
- red       below stall speed at the low end
            above velocity never exceed ('red line') at the high end
The ground speed is displayed at the bottom. The target speed for autopilot operation will be displayed at the top as well as the magenta speed bug if selected.

(4) Attitude indicator
Shows the roll and pitch attitude of the aicraft with respect to the earth (artificial horizon).

(5) Altimeter
Shows the current altitude above sea level in feet. Again, the magenta trend indicator shows what the altitude will be in 6 seconds at the current rate of climb.
A bar having a length equivalent to 100 ft therefore indicates a rate of climb of 1000 ft/min.
The height above ground is shown at the bottom.
If a target altitude is selected, this will be displayed in magenta at the top and the altitude bug will be shown.

(6) Vertical speed indicator
Displays the current rate of climb or descent in feet per minute. For autopilot operation, the target rate of climb is shown at the top.

(7) Nearests airports
Shows the distance of and direction to the two nearests airports. The distances are displayed in nautical miles. The directions are shown with respect to the
current heading. In this example, the nearest airport is at the 4 o'clock position at a distance of 6.6 nm. The second airport is right behind at a distance of 13

How do I operate the autopilot?
The autopilot can stabilize the heading, airspeed, altitude as well as the vertical speed. The autopilot cannot be switched on and will disengage when one of the
following limits is exceeded: bank angle larger than 60 degrees, pitch angle larger than 45 degrees, airspeed less than 1.2 times the stall speed or when the
aircraft is on the ground. These limits are exceeded for example if you fly a looping with heading mode engaged - the autopilot will disengage as soon as the
nose is 45 degrees above the horizon.

The heading mode can be activated and deactivated by tapping on the heading indicator (2). The box around the heading will change its color to green to
indicate the heading is controlled by the autopilot. If no heading was selected so far, the current heading will be selected and shown in magenta. The target
heading can be changed by tapping the + / - buttons (8) below the heading indicator. Touching these buttons for a longer time will repeatedly change the
selected heading by 5 degrees. The target heading can be changed while the heading mode is engaged, the autopilot will then turn the aircraft to the selected

The airspeed mode / auto-throttle will adjust the engine power to keep the selected airspeed. Enable / disable this mode by tapping on the airspeed indicator
(3). The target airspeed is shown in magenta at the top and can be changed by the + / - buttons (8) below the airspeed indicator.

Hold a constant altitude. This mode is perfect for cruise flight at a constant altitude. Tap the altitude indicator (5) to activate this mode. When engaged, the
autopilot will climb / descend to the target altitude and level off. The vertical speed in this phase can be selected by using the + / - buttons below the vertical
speed indicator (6). When the target altitude is changed by tapping the + / - buttons (8) below the altitude indicator, the autopilot will initiate a climb / descent
to the new altitude. The vertical speed for this will be the last selected vertical speed, provided it has the right direction. If a descent would be required to reach
the new altitude and the last selected vertical speed was a climb at 1000 ft/min, this would be changed to a default of -1500 ft/min and vice versa.

V/S - vertical speed
Climb / descend at a constant rate. When engaged, the autopilot will try to climb / descend at the selected vertical speed. If the aircraft cannot climb at the
selected vertical speed, it will loose airspeed until the autopilot disengages at minimum speed. This mode can be selected by tapping the vertical speed
indicator (6). The v/s mode will override the altitude mode, so this can be used to leave an altitude that was previously held constant by the autopilot. On the
other hand, if the altitude mode is active, the vertical speed mode will disengage 500 ft before reaching the target altitude to allow levelling off and avoid
crossing a selected altitude.
