What happens to the nose of the aircraft when power is increased from idle to go-around N1 during low flight speed?

When power is increased from idle to go-around N1 during low flight speed, the aircraft's nose typically exhibits an initial nose up tendency due to the increased thrust. However, if we consider the dynamics at play, particularly the balance of forces and the moment around the center of gravity, the increased drag and the aerodynamic characteristics at lower speeds may overpower the lift generated by the increased thrust.

As power is applied, the thrust vector changes, and the aircraft may experience a moment that causes the nose to initially pitch down. This response is particularly prominent in certain aircraft configurations where the increased thrust can lead to an increase in the angle of attack, potentially causing a moment that pushes the nose downward due to inadequate lift at low airspeed.

Therefore, the observation of an initial nose down tendency aligns with the aircraft's reaction to the aerodynamic shifts during a power increase in this scenario. The conditions of low flight speed also contribute to increased drag, which may further affect how the nose responds to the added thrust.
