-
8227. Wing dihedral, a rigging consideration on most airplanes of conventional design, contributes most to stability of the airplane about its
longitudinal axis
-
8228. Other than the manufacture maintenance manual what other document could be used to determine the primary flight control surface deflection for an imported aircraft that is reassembled after shipment?
Aircraft type certificate data sheet
-
8229. If a pilot reports that an airplane flies left wing heavy, this condition may be corrected by
increasing the angle of incidence of the left wing, or decreasing the angle of incidence of the right wing, or both
-
8230. If the vertical fin of a single-engine, propeller-driven airplane is rigged properly, it will generally be parallel to
the vertical axis but not the longitudinal axis
-
8231. An airplane which has good longitudinal stability should have a minimum tendency to
pitch
-
8232. As the angle of attack of an airfoil increases, the center of pressure will
move toward the leading edge
-
8233. The angle of incidence is that acute angle formed by
a line parallel to the wing chord and a line parallel to the longitudinal axis of the aircraft
-
8234. An airplane's center of lift is usually aft of its center of gravity
so that the airplane will have a nose-heavy tendency
-
8235. An airplane is controlled directionally about its vertical axis by the
rudder
-
8236. The elevators of a conventional airplane are used to provide rotation about the
lateral axis
-
8237. Washing-in the left wing of a monplane, for purposes of rigging corrections after flight test, will have what effect on the lift and drag of that wing?
Both drag and lift will increase due to increased angle of attack
-
8238. What type of flap system increases the wing area and changes the wing camber?
Fowler flaps
-
8239. If the right wing of a monoplane is improperly rigged to a greater angle of incidence than designated in the manufacture's specifications, it will cause the
airplane to be off balance both laterally and directionally
-
8240. The chord of a wing is measured from
leading edge to trailing edge
-
8241. When the lift of an airfoil increases, the drag will
also increase
-
8242. What physical factors are involved in the aspect ratio of airplanes wings?
Span and chord
-
8243. Improper rigging of the elevator trim tab system will affect the balance of the aiplane about its
lateral axis
-
8244. An airplane that has a tendency to gradually increase a piching moment that has been set into motion has
poor longitudinal stability
-
8245. The purpose of wing slats is to
reduce stalling speed
-
8246. The angle of incidence of an aiplane at rest
does not change when in flight
-
8247. Buffeting is the intermittent application of forces to a part of an airplane. It is caused by
an unsteady flow from turbulence
-
8248. Movement of an airplane along its lateral axis (roll) is also movement
around or about the longitudinal axis controlled by the ailerons
-
8249. The primary purpose of stall strips is to
stall the inboard portion of the wings first
-
8250. Rigging and alignment checks should not be undertaken in the open; however, if this cannot be avoided, the aircraft should be positioned
with the nose into the wind
-
8251. the correct dihedral angle can be determinded by
using a dihedral board and bubble level along the front spar of each wing
-
8252. The dihedral angle of a wing may be measured by placing a straightedge and level protractor on the
front spar
-
8253. Where would you find precise information to perform a symmetry ailgnment check for a particular aircraft
Aircraft sevice or maintenance manual
-
8254. Where is the buttock line or buttline of an aircraft?
A width measurment left or right of, and parallel to, the vertical center line
-
8255. Where is fuelage station No. 137 located?
137 inches aft of the zero or fixed reference line
-
8256. Proper wing twist in a sheet metal consturcted wing can usually be checked by utilizing a
bubble level and special fixtures described by the manufacturer
