The AIC relating to Servo Transparency (Jack Stall) quotes Airbus stating that 'Density Altitude' effects the likelihood of encountering the phenomenon. The CAA AIC goes further and states 'high density altitude' indicating that the risk is greater, the higher the aircraft.
If the air is less dense as altitude increases, how can Servo Transparency (caused by aerodynamic control loads) be more likely? Discuss.
