| Other factors such the lift provided by the fuselage, tailplane and control surfaces, were ignored. |
| The cantilever all-metal tail has a hydraulically powered rudder and single-piece all-moving tailplane. |
| The fuselage is of light metal construction and parts of the tailplane are of composite structure in order to reduce radar signature. |
| During this visit they also decided to build a new tailplane and new control surfaces. |
| Installing the tailplane is now extremely simple: first roughen the joint surface of the integral root fairings using coarse abrasive paper. |
| Aircraft with significant tailplane icing can experience tailplane stalls, which can lead to steep nose-down descents. |
