TOGA N1 value is what percentage?

Explanation:
TOGA N1 is the fixed thrust target the FADEC commands when Takeoff/Go-Around is selected. For the CRJ-550, that target is 99.5% N1. This near-maximum setting gives the necessary takeoff thrust while leaving a small safety margin below 100% to avoid running the engine at its absolute limit and to accommodate system tolerances and varying conditions. In practice, you’ll see the engine stabilize around that level during TOGA, with slight deviations due to weight, altitude, temperature, or runway factors. Numbers like 98% or 99.0% would not provide the standard takeoff/go-around thrust, and 100% would remove the margin and isn’t used as the normal TOGA target.
