To have more icons than throttle you have to enable CEM and temp effects in the difficulty options.
To have them back on your screen:
- right-click on the in-game screen
- open new window
- right-click on the windows and go to properties
- you have a menu opening with several options you can select to show up in your new window
- select engine parameters (or something like that, writing this from memory)
- you also have several options on how to display the info, window trasparency, border on/off and so on. For engine parameters you should have an option if to display in analog (little icons) or digital (numbers).
In a window you can put any info available in the properties menu. Personally I have one little window with the engine parameters, one showing plane systems and damage and one for radio/server messages.
To select an existing window, alt+left click on it.
Hope you manage to sort out what I wrote
