Certainly gives a new perspective to large thrust variations at altitude.
On the A319/320 VMO/MMO is 350/.82 , however the VD/MD is 381/.89 and structural inspection is only required from VMO + 20, MMO + 0.04. (FCB15)
So I think in general there is still quite a bit of margin on the topside of the speedband, where this does not exist at the bottom. So maybe leave the thrust and accept an overspeed?
Difficult scenario though!
The aircraft should still take 2.5g up until VD/MD btw.
