is this safe?

saw this on my return flight from krakow but didn’t notice anything while in the air.

Yes, that is a thrust reverser

Building on this answer - the doors open to allow the engine thrust to redirect and thus slow the plane down on landing. Once the plane slows down enough, you’ll see the doors slide shut again.
Now, if you see that door open mid-flight, that would be very concerning (to say the least).

Unless you're flying the C-17.

Or a DC-8.

To be honest, few seeing this inflight survived to tell the tale. That is why there are layers upon layers securing the deployment logic of the thrust reversers.
Just one example from the A320:
All these conditions have to be met at once to be able to activate the solenoids in the thrust reverser HCU.

as someone who knows nothing about planes, thanks for all your answers!

Only if you want to stop before the end of the runway.

To be fair… most Auto Brake systems are designed to obtain a certain rate of deceleration not necessarily braking force. So regardless of whether the reversers are deployed the plane will still decelerate at the same rate (it’ll just rely solely on the wheel brakes assuming traction isn’t an issue obviously)

It would not be very safe if it didn't open
doom_pizza@reddit
It’s supposed to do that. It helps slow the airplane down.
ValpoPilot@reddit
If that was deployed in the air you definitely would’ve noticed

thrust reverse, you kinda need those if you want the plane to slow down without setting the brakes on fire.
