The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it.
The effect is of sufficient magnitude that hunters must adjust their target hold off accordingly in mountainous terrain. A well known formula for slant range adjustment to horizontal range hold off is known as the Rifleman's rule. The Rifleman's rule and the slightly more complex and less well known Improved Rifleman's rule models produce ...
Stabilator or all-moving tail: In transonic flight shock waves generated by the front of the tailplane render any elevator unusable. An all-moving tail was developed by the British for the Miles M.52 , but first saw actual transonic flight on the Bell X-1 ; Bell Aircraft Corporation had included an elevator trim device that could alter the ...
The V-280 made its first flight on 18 December 2017 in Amarillo, Texas. [3] On 5 December 2022, the V-280 was chosen by the US Army as the winner of the Future Long-Range Assault Aircraft program to replace the Sikorsky UH-60 Black Hawk. [4] [5] As of April 2024, limited user tests are planned for 2027 to 2028 with the first deployment expected ...
The winds passing on both sides of the tail rotor make it teeter between being effective (providing thrust) and ineffective (not providing thrust). This creates a lot of pedal work for the pilot to eliminate unintended yaw. Tail rotor vortex ring state - Wind moving in the same direction as the tail rotor moves air. With pusher tail-rotors ...
Wing sweep and taper cause stalling at the tip of a wing before the root. The position of a swept wing along the fuselage has to be such that the lift from the wing root, well forward of the aircraft center of gravity (c.g.), must be balanced by the wing tip, well aft of the c.g. [ 68 ] If the tip stalls first the balance of the aircraft is ...
Formation take-off of an RAF Tornado GR.1 and a Tornado F.2 prototype in September 1982 When the agreement was finalised, the United Kingdom and West Germany each had a 42.5% stake of the workload, with the remaining 15% going to Italy; this division of the production work was heavily influenced by international political bargaining.

When the aircraft's speed reaches zero and it stops climbing, the pilot maintains the aircraft in a stand-still position as long as possible (this is greatly helped by thrust vectoring on newer fighter aircraft), and as it starts to fall to the ground backward, tail first, the nose drops through the horizon to a vertical down position and the ...
