Testing instructions

• Check flyPad Settings > Realism - Check that MCDU Input and Pause at TOD Settings options still work as per normal and that there is no regression
• Quick Settings -> New options: Pause at TOD and Simrate Controller
  • Ensure all localisation screens and hover text work
  • Ensure visually css is not broken (including with other localisation i.e. RU/PL
  • Check that the toggle for pause on TOD works and that this syncs with what is in the Settings > Realism page.
  • Check that the new simrate indicator in the status bar shows the simrate accurately
  • Check that you can increase and decrease the simrate (until limited by our built-in simrate reduction, which should be around 4x for most people)
    • Note that the automatic simrate reduction feature will still affect this, so if simrate is reduced because of low frame rate or performance issues, this is as designed and expected.

Pause on TOD Tests:

• Expected Behavior/Notes:
  • Button Status/Color: When you first activate this in the Quick Controls the button's background will be orange (and say Standby)
  • NOTE: Critical MSFS Sim Bug possible if you ALT-TAB while panning the camera with the mouse look option (MMD by default). Do NOT Alt-TAB while panning the camera. This will make the pop-up unable to be dismissed and you will have to restart. - As this is already a bug on master this is not considered a regression.
  • Armed State (Green): This will only update to Armed (green background), when all the pre-conditions for Pause on TOD are met.
    • A valid flight plan with a valid T/D must be first calculated (i.e. fill in INIT-B, PERF pages on MCDU).
    • Plane must be in the air - i.e. FMGC flight phase is on either CLIMB or CRUISE.
    • Distance to T/D is equal to or less than the configured T/D pause distance (default 10nm)
    • T/D point has not already been reached.
  • A/P guarding - If the A/P is disconnected ABOVE the inputted transition flight level (default 10000 FT if not specified) the sim will pause and for 10 seconds, pause on T/D will be on standby. This 10s cooldown will be reflected in the Quick Setting button's status.
    • Why A/P guarding: Necessary if A/P is disconnected to pause to prevent plane from going off course.
    • 10s cooldown: This is to prevent repeated activation after unpause that interfere with the user's ability to fly and re-engage A/P as desired.
    • Quirk: This A/P guarding logic i.e. above the transition flight level logic is hidden to the user and is not displayed in the button's status.
      • In the future this may be displayed somehow, but as the two logic gates are independent of each other, this is just for tester's awareness that this exists.
    • After A/P guarding pause, for 10 seconds, Pause on T/D will not be armed. This will be reflected in the button's background colour.
    • Pause due to A/P guarding can be repeated, unlike the pause that occurs when T/D is reached.
  • Important: After T/D is reached and the sim paused. T/D Pause will activate and is then both T/D pause and A/P guarding will be disabled for the rest of the flight, the quick settings button returning to a Standby/orange state until the next turnaround, based on FMGC status (READY/DONE). This means engines must be shutdown and cockpit returned to a turnaround state on the ground after landing.
• Do a short flight (with init-b/perf pages filled in). Ensure Pause at TOD feature works as per normal after arming it in quick settings menu (green top border visible)
• Turnaround -> After completing the full proper turnaround procedure, and after departure with another complete flight plan, check that T/D pause is now fully re-enabled and that the Armed (green) state can be entered again, and that pause on T/D works on this turnaround flight.
• Retry -> Change distance (Settings > Realism - Pause At TOD DIstance) and ensure that pause on T/D correctly pauses at this distance.

Still needs localisation keys, to be added before merging

LGTM, let's just check package.json formatting before merging, but not relevant for testing.

Will fix EDIT: and done

[ExampleWasTaken]

I think the simrate box needs UI improvements. At the moment it doesn't align with anything. The clock is neither in the middle of the box nor below the gap between the simbridge and keyboard button.

I suggest centering the clock and displaying the next simrate in the buttons instead of the chevrons.

So if you're at normal simrate, the "previous" button (i.e. decrease) button is disabled. At 4x simrate the left button reads 2x and the right button reads 8x.

The current simrate could be displayed as part of the box title, meaning below the clock. E.g. 4x Simrate

UI improvements will probably need to be in another PR at this stage, I don't anticipate having the bandwidth to adjust it further in the next 2 months. Potentially a good first issue for new contributors.
