I am somewhat out of date with the newer Boeing's, but back in my B747 days some, but not all, had Flap Load relief? I say not all because on an SP type a Captain 'thought' it had it and over sped the flap limits and reported the system had not worked in the Tech Log; the subsequent inspection required removal and NDT of the flap carriage bolts, a some-what major job. I should have expected such a system would have been easily installed on a digital age B787?
On another occasion during the antiquated post major maintenance stall check, the senior Capt. had to push the RB211's to the wall to avoid a @.
Flight recovered and all aboard chuckled, until the QAR read out came through, 3 of 4 engines had exceeded their N1 limits, again left to Engineering/Maintenance to sort out.
Luckily for the above Captains they were not flying for a QR type Co.
