| 11. | The fuselage tapered rearwards to a mid set tailplane and fin.
|
| 12. | It has a retractable tricycle landing gear and a low tailplane.
|
| 13. | The tailplane was externally braced and the elevators carried trim tabs.
|
| 14. | The tailplane features five vertical tail surfaces for improved directional stability.
|
| 15. | At the rear the tailplane was mounted at mid-fuselage.
|
| 16. | But with care a lifting tailplane can be made stable.
|
| 17. | Anticipating supersonic performance, the tailplane was all-moving.
|
| 18. | Most modern airliners adjust the tailplane center of gravity moves.
|
| 19. | Trim changes were minimized by programmed tilting of the tailplane.
|
| 20. | The tailplane leading edge of the first prototype was modified,
