Hi Dazz,
It's understandable that the issue of not being able to access unlimited fuel is quite perplexing, especially when the settings are geared for full assistance. The situation you're facing is indeed a complex one, but let's break it down and find a solution together.
1. Configuration Check
First of all, ensure that the assistance options are properly configured. For unlimited fuel:
For Microsoft Flight Simulator (2020):
- Navigate to the Options > Assistance > Piloting menu.
- Find the Unlimited Fuel option and make sure it's turned On.
For X-Plane 12 (if relevant):
- Navigate to the Settings > General menu.
- Find the Fuel section and select Unlimited Fuel.
2. Aircraft-Specific Issues
If the problem persists, it could be an issue related to specific aircraft or liveries. As you've mentioned the A320, consider checking if there are any known bugs or updates related to it or any other aircraft you are experiencing this issue with.
3. Graphics and System Performance
Your system specifications seem more than adequate. However, a simple restart of the application or system might solve an unseen glitch.
4. Software Updates
Make sure that your simulator is up-to-date. Sometimes, issues are resolved with new patches or updates.
From my knowledge, these steps should assist you in resolving the unlimited fuel issue. Please don't hesitate to update this thread if you have any further questions or if you require additional clarification on any of the points mentioned above.
Happy flying!
P.S. If you are utilizing any third-party mods, add-ons, or liveries, make sure to double-check their compatibility as they may interfere with certain settings, including fuel options.
