a320 wing tip brake slat recycle

hi all
i hv a question on the airbus a320 wing tip brake.

assume that after take off we have an ecam fctl slat locked (wing tip brake on)
i read from the fcom that the recycle is not reccomended.

soo if want to retract flaps to reduce the fuel burnt is it possible??

thank you in advance

WTBs activate in case of asymmetry, mechanism overspeed, any symmetrical
runaway or uncommanded movement of the surfaces.

They can't be released in flight - only on the ground.

They use B+G for slats and right wing flaps, and B+Y for left wing flaps.

If the slats are locked, the flaps still move.
In your scenario, after TO, if the slats lock on selection of Flaps 1, the Flaps will move to 1+F (10deg). If you have selected Flap 0, the slats lock but the flaps retract to 0.

Above post is correct.

The ECAM shall indicate Max Speed 200kts. Be careful here, as it is so easy to overshoot the speed even on A/P and A/T, and you will get that repetitive chime on just a few knots above 200kts.

I select speed max 190kts.

Slats or flaps locked is a non recycle due to possible damage caught by the wing tip brakes as opposed to a Slats / Flaps fault where a recycle is an option.

There are two reasons for the jam. 1) computer problem and 2)WTB. In the computer problem case ECAM tells you recycle but in the other case it doesn't.
