For those not familiar with the B737:
On a Dual-Autopilot approach, the aircraft back-trims at around 400'. In case of a subsequent manual GA (normally the autopilot handles the GA) for whatever reason, a downward force is needed on the joke to avoid over-rotation...this can surprise sometimes new left-seaters during their sim-training.
Does anyone know the distance/time between the THY and the preceding landing aircraft, previous post say a B752?
Were LVP's in progress?
