====== Frequently Asked Questions ======


===== General =====

**__How do I see FPS on my monitor?__**

Press CTRL and F1 keys at the same time to toggle the white overlay in the lower left corner.

**__I purchased a boxed version of Aerofly FS 2, how do I run in VR mode?__**

By default the Aerofly FS installer creates two special start entries in the program group folder of the Windows start menu for you; one for Oculus VR and one for Steam VR. Use one of these to start Aerofly in VR mode.

===== Aircraft =====

**__Why don't engine sounds change when I move the throttle?__**

The sound of the engine is determined by the engine rotation speed and with the constant speed propellers of the P38 that rotation speed is kept constant by changing the angle of the propeller blades. If the rotation speed is too high the governor adjusts the blade angle to a more coarse setting which increases the blade angle and the blades bite into the air more strongly. Then if the speed decreases the blade pitch is reduced to reduce the load on the engine. The blades are adjusted so quickly that the rotation speed is pretty much constant throughout the entire flight, unless you fly very slow and with low power.
This means the propellers spin at a constant speed all the time and therefor the sound is very monotonous, just like in the real aircraft.

===== Support =====

**__I was just told to post my TM log on the forum, how do I do this?__**

Our forum doesn't allow for *.log file extension due to security reasons, simply rename the .log to .txt and attach it to your post. The TM log is located in your documents\Aerofly FS 2 root folder.
