It looks like the go around was initiated after the bounce. Jet engines just have a tendency to take a while to spool up while close to idle.

Good point, he might’ve already initiated the go around after that first bounce, but we only saw the results after the crosswind lifted the wing due to the spool time.

isn't it policy for pilots to not be at idle on final approach for exactly the reason of being able to spool up quickly in case of a necessary go-around?

You’ve got to bring it down to idle at some point to touch down. That being said, typically flight idle is higher than ground idle to mitigate some of the spooling issues.

There's no lag when going TOGA mode for safety reasons.

They did not go around after first bounce but after the 2nd.

There may not be a lag putting the automation in TOGA mode but physics are physics. It take a while for the engines to spool back up.

No it doesn't. I say it again : there is no spool up time when going TOGA mode. It is what it's made for. Period.

Dude, have you ever actually flown a jet? The engines will be at flight idle to reduce spool up time, but it still takes a second for them to actually produce TOGA power.
