This configuration may reduce pitch control effectiveness if the elevators are outside the propeller slipstream, or improve it for many transsonic aircraft because it isn't in disturbed air behind the fuselage, particularly at moderate angles of attack. For flight at high angles of attack, an elevator mounted below the wing is preferred as it isn't blanked by disturbed air from the wings. An aircraft with a T-tail may be easier to recover from a spin, as the elevator is not in a position to block airflow over the rudder, which would make it ineffective, as can happen if the horizontal tail is directly below the fin and rudder.[1]
