An outlet door is provided for covering an outlet defining an outlet area in a skin () of an aircraft component to exhaust a flow of heated air to an outside of the aircraft. The outlet door includes a body defining a door area and extending between a leading edge and a trailing edge and a linkage () connecting the body to the aircraft, permitting the body to transition between at least one of an open position and a closed position. In the closed position, the body at least partially occupies the outlet area. In the open position, the body forms an angle with the skin of the aircraft. The leading edge of the body and the skin of the aircraft define a separation () therebetween when the body is in the open position. The separation defines and air flow for mixing cold air with the flow of heated air.

Tailplanes and empennages for aircraft are disclosed. An exemplary tailplane disclosed includes a stabilizer having a fixed shape and an elevator movably secured to the stabilizer. The elevator is movable from a neutral position relative to the stabilizer. The stabilizer and the elevator define an airfoil cross-sectional shape having a positive camber when the elevator is in the neutral position. The positive camber of the airfoil cross-sectional shape may facilitate movement of the elevator during some flight conditions. Also disclosed are tailplanes having camber distributions that vary along the spans of the tailplanes.
