If you’ve ever pulled up an approach plate on your iPad at night, you know how bright it can be–the nearly all-white chart is like shining a flashlight directly into your eyes. It’s certainly not good for your night vision. While most aviation apps have a dimming feature built-in, even this is usually insufficient.
Fortunately, the iPad has an extremely handy feature built in that allows you to invert the colors on the screen. While it can make some charts look a little odd (sectionals), it is perfect for approach plates.
Here’s how to enable it:
- Go to the Settings icon on the iPad.
- You’ll be at the “General” selection on the left by default; scroll down on the right side and select “Accessibility”.
- Select the “Triple-click Home” option now at the bottom of the list.
- Select “Invert Colors” from the list, and you’ll see a check mark at the right when it’s selected (this is labeled ‘White on Black’ for those that haven’t updated to iOS 6 yet).
Now, when you click the home button three times quickly (circular button on the lower front of the iPad), you’ll invert the colors of the screen. This makes for a much better low-light viewing experience at night in the cockpit. This works for every app that runs on your iPad, so you may find other uses for it too.
