Do Air France use V-bar flight directors?
(Reason for extreme control inputs.)

I had a similar situation, when the copilot started mixing the (bright pink) flight director with the (black) aircraft index on the attitude indicator. The FD said turn left, and he thought the aircraft was turning left (mixing FD with aircraft index), so he gave the aircraft full right, and nearly turned the aircraft upside down. Again, this was just at 1500 ft on t/o, at night with no ground lights. Luckily the aircraft shouted ‘bank angle’, while I was changing frequency, and I recovered.

Note: In the AF go-around the FD would have indicated 10 degree up pitch, or less if the speed had dropped off. If the f/o was mixing FD and aircraft index, he may well pull back harder - not understanding why the aircraft index (aka the bright pink FD) was not moving with his inputs. So he pulls harder and harder.
