Engine thrust limit indications

Hello there,
Does anyone know if there is any aircraft type which displays on the engine indications apart from it s maximum go-around thrust also reduced thrust as calculated by fmc/at computers?
If so, could you elaborate on it?

Able to supply any pictures?

In the 744, the reduced GA thrust is whatever is needed to maintain 2000 FPM climb. Since it is dynamic, there is no separate indication.

To paint the full picture for anyone using that as a source of fact; it will use a reduced GA thrust to maintain a minimum of 2000fpm, provided the climb rate is above 600fpm. Otherwise the TOGA commands will pitch for 15 degrees nose up if 600fpm is not achievable (ie windshear, engine failure/s).

Does that assume the flight director is on? What if raw data for example?

I believe the Flight Directors will pop-up if they are off when a GA switch is pressed on the 744. Similar, I think on the 767 & A380.

If you are only talking about Go Around thrust then the Avro RJ will at the push of a button but normally GA is full rated on most types.
