Due to how we want the Fuel Level Gauge to function (ref. Section 2.1), we need to create duplicates of the Bar Gauge and Image Widget and have them appear under a Visible Condition when the Fuel Level drops below 15%.
Duplicate the Bar Gauge.
Select the BG Fuel gauge in the Pages tab
Copy and Paste the BG Fuel gauge
Rename the new / copied gauge to: BG Fuel Low
In the properties bar: (Supplemental 2.6.1 Fuel Low Bar Gauge)
Change the X & Y Position for the BG Fuel Low gauge to be the same as the BG Fuel gauge
Change both the Day & Night Colors of the BG Fuel Low gauge to Red
(Supplemental 2.6.1 Fuel Low Bar Gauge)
Duplicate the Image Widget
Select the IW Fuel gauge in the Pages tab
Copy and Paste the IW Fuel gauge
Rename the new / copied gauge to: IW Fuel Low
In the properties bar: (Supplemental 2.6.2 Fuel Image Widget)
Change the X & Y Position for the IW Fuel Low gauge to be the same as the IW Fuel gauge
Change both the Day & Night Image for the IW Fuel Low gauge to be a Red image
(Supplemental 2.6.2 Fuel Image Widget)
Create a Visible Condition for Fuel Level
Select the BG Fuel gauge in the Pages tab
In the properties bar, select to enable Visible Condition under the Advanced Features section
The Visible Condition Setup window will appear.
Complete the Visible Condition Setup
Repeat these steps to complete the Visible Condition Setup for:
BG Fuel Low gauge
IW Fuel widget
IW Fuel Low widget
Bonus:
Try Creating a visible condition for the Load @ RPM Gauge, so that when the Load is:
- Below 75%, the Ellipse Widget is Green
- Above 75%, the Ellipse Widget is Red
