At QR we always did a takeoff review just before takeoff…..TOGA TOGA LNAV VNAV ARMED…4000* feet , heading 300 flaps 5 or something like that…(I was pretty sure that was actually adopted from Emirates as we had so many managers from there
seems like that would have caught this error, so wondering if Emirates no longer practices this.
after takeoff they would have been probably 85 tons over max landing weight which complicates the decision to return also coupled with the punitive management in middle east where you know you will likely be fired for any embarrassment on company
