For info, my airline operates NG and Max when not grounded and I have never flown older versions.
Further reading on this issue highlights more questions about how to handle this situation.
Our up coming sim profile calls for a diversion to our takeoff alternate following the flap asymmetry after takeoff.
The only QRH reference is to set the flap handle to the nearest detent that is equal to or less than the smallest indicated flap position. In our case that would be flap lever to 2 as the takeoff would have been flaps 10.
Does this imply the lever must remain at position 2 or is it permissable to place the lever at 0 for the diversion in order to retract all LE devices.
Cheers.
I wouldn't retract them completely unless the QRH guides you to. And its possible you'll be setting Flaps 5 depending on when/how the assym presents itself (i.e. 10* and 7* indications)
It can be a confusing checklist, but my understanding (and my operator has that same note about returning to normal ops) is you can attempt one reset. So from flaps 10 to 5 you get an assym, reset flaps to 10 and see if normal ops returns. If it does, continue with normal ops and retract. If not, set it to the smallest detent and continue with the checklist/divert.
Take at look at your company's Trailing Edge Flap Disagree QRH procedure. It may actually provide some guidance if you have flap issues during retraction.
