The effects on lift and drag of hull geometry, flap geometry, weight, balance, power and tail surface
definition could therefore all be reviewed graphically, allowing the design to be optimised.
Movements of the caudal axis probably deformed the tail surface
Moreover, the aircraft's tail surface
, which is critical for providing lift at the earliest moment of takeoff, can't be seen at all.
To help, the horizontal tail surface
usually is mounted at a slightly negative angle of attack (AoA).
However, since the Cessna 150/152 airplanes are used for training, aerobatics and spins, which place additional loads on the vertical tail surface
, the FAA wants technicians, owners and operators to remain aware of the problem.
A spoiler--maybe made from a length of 2x4 lumber--secured to the top of the wing and tail surfaces
can be effective at preventing movement of the covers while ensuring strong winds don't shift the airplane's position.
They are looking at relying on wireless technology as "an additional layer of redundancy" for moving critical wing and tail surfaces
that control flight, according to spokesman Clay McConnell.
The Su-33 is a single-seat ship-based STOBAR fighter, with upward folding wings and horizontal tail surfaces
(for hangar storage); it is equipped with probe-and-drogue flight refuelling capability.
Production and installation and removal of traffic boards (4/1, 18/1, tail surfaces
, ZugseitenflEnchen) for the application of the VRR ticket products.
But, the aircraft's wings, tail surfaces
and engine nacelles will be built by Antonov in Kiev.
Some propeller planes were able to approach near-transonic speeds in a dive, but in certain planes, pilots found it difficult to pull out of such dives due to interacting airflow between the wings and tail surfaces
