Horizontal stabilizer - Horizontal stabilizer is a fixed wing section whose job is to provide stability for the aircraft, to keep it flying straight. The horizontal stabilizer prevents up-and-down, or
pitching, motion of the gilder/plane nose.
Without the horizontal stabilizer wht will happen?
The detachment of the horizontal stabilizer would cause the aircraft to pitch down heavily and a steep descent would induce a spin.
Of couse it can still stay airborne....... for 5 sec LOL!
Alaska Air Flight 261: the horizontal stabilizers jackscrew jammed (which is when the jackscrew - a device which controls pitch trimmimg - was not correctly lubricated). The plane crashed off the coast of California in 2000. The result of the jammed jackscrew meant it was extremely difficult to control the pitch of the aircraft, and considering the MD80s run off hydraulic power, the controls were very heavy to operate.
Vertical stabilizer-
The stabilizer increases yaw stability and yaw damping, and as result makes the glider substantially less susceptible to getting into oscillations, and makes it easier to recover from them. It also slows down the glider's roll response slightly, and changes the roll / yaw coupling somewhat.
Without the vertical stabilizer what will happen?
On November 12, 2001, American Airlines Flight 587 ran into air turbulence shortly after taking off from Kennedy International Airport. The vertical stabilizer broke off from a combination of the air turbulence and pilot attempts to compensate for the turbulence.. The Airbus A300 crashed into the Belle Harbor neighborhood of Queens; a borough of New York City. The crash killed all 260 people in the plane and 5 people on the ground. The broken vertical stabilizer was found in the bay a few miles before the airplane hit the ground. When the vertical stabilizer came off the plane turned sideways, its engines broke off, and all control was lost.
