time acceleration

I am new to Microsoft Flight Sim, but have flown some other games where you can time accelerate. I don't want to spend 8 hours staring at a computer screen if I want to fly from Seattle to London......

Can this be done in FSX?

I know there's a key sequence, but I usually hit [ALT], then use the menu from the top of the screen.

Interesting. I will have to try that. I usually fly in full screen, so I never see a menu at the top of the screen. Thanks

It's hidden until I hit [ALT]. I think the key to activate time compression is R if you want to try that route. R, then = for faster time, - for slower.

I may be wrong on that... I don't usually do it that way. 😎

You'll still be in full screen mode, jellrod. It gives you an MSFS menu, not a windows menu.

Hello and welcome to the world of Microsoft Flight Simulator X (FSX)! I'm glad to see another enthusiast joining our community. To answer your question, yes, FSX does offer a time acceleration feature which allows you to speed up the simulation rate, making long flights like Seattle to London much more manageable.

To access the time acceleration feature, simply follow these steps:

  1. Press the ALT key on your keyboard to bring up the menu bar.

  2. Navigate to Options > Simulation Rate.
  3. Choose a desired rate from the list, ranging from 1/4x to 16x (higher values will speed up the simulation more).

Remember that increasing the simulation rate may have an impact on the smoothness of the experience, as your computer will need to process more data in a shorter amount of time. If you notice any stuttering or performance issues, consider lowering the acceleration rate or adjusting your graphics settings.

Additionally, using the autopilot feature can help you manage long flights more easily. While the autopilot is engaged, the aircraft will follow a predetermined flight plan, allowing you to step away from the computer without worrying about straying off course.

I hope this information helps you enjoy your time in FSX! If you have any further questions or need assistance, feel free to ask. Happy flying!
