Spoilers are a less-known aspect of flight, but are very useful! Almost every plane has them!
Overview
Spoilers are used to help an aircraft slow down. They are located on the top of a plane’s wing, end extend upward, creating drag. Not all planes have them, though. Small planes, such as the Cessna 172 don’t have them.
Operation
Similar to the flaps, you must hold down the SPOILERS button until you see the options. The button is located to the right of your screen. There should be 3 options: OFF, FLIGHT and ARMED. OFF means that the spoilers are off. FLIGHT means they are extended mildly in mid flight. ARMED means that the spoilers are off, but will deploy at full once you touch the ground. To select these options, scroll you finger up or down until your option is highlighted, then release.
Appropriate operation times
The spoilers should be OFF until you start to descent to your destination airport. Extend them to FLIGHT if your speed increases too drastically during your descent. If under 10,000 ft and you no longer need the spoilers, set them to OFF. If they need to be flight until touch down, set them to armed right after both your wheels touch down. Then, once you’re at parking, set the spoilers to OFF
