Spoilers not working on some aircraft


On some planes, most notably the B777-300ER, the spoilers do not deploy on touchdown despite spoilers being armed. On other aircraft, such as the A220-300, this is not an issue.

Device: Samsung Galaxy A31
Operating system: Android 11

Can you share a video of this - will help to understand the issue better.

Are you using the parking brake or auto brakes? Sometimes they don’t deploy or they retract when parking brake is used

If you land and flick your throttle to reverse and back right away, I’ve noticed that the spoilers de-arm themselves as well


I can share a screenshot(just look at the stuff at the bottom of the screen

The spoilers will only visibly deploy when the thrust reversers are engaged.

This ☝️, and if you want to keep them after reverse, slowy increase the throttle (which is reversing to minus %) until 0%, spoilers will keep stay. Immediately turn back to 0% won’t keep spoilers stay.


That’s incorrect, they should deploy the moment the landing gear touches the ground.
