the foreground 744 has only outer slats extended ?

Is that possible ? the flaps looks the same, as long as I can see the background ones.

Thanks in advance for your help.

During reverse thrust the inboard and the ones between the engines retract to reduce the risk of object beeing thrown upwards from the reverser and damage the slats...

If it ain't Boeing (or McDonnell Douglas), I am not going.

In the name of accuracy (and my general anal persuasion) B747 type aircraft do not have slats. They have variable camber flaps installed outboard of the inboard engines and krueger flaps installed inboard of the inboard engines.

And yes, the B744, and some B747 classics, will stow some of the flap segments to protect the leading interior from FOD.

If it's not specifically prohibited, it's authorized! When seconds count...the police are minutes away!

Fast forward to about 5:45 to see it in action.

But why do they extend again after idle?

There is no better way to fly.

Usually, the flap handle will not be moved during the thrust reverse procedure, that is, they crew will wait until they are off the active runway before they clean up the flaps and leading edge devices. Because the flap handle is still in the extend position after the TR's are retracted, the leading edge devices will re-extend.
