Questions with All Solved Solutions.
Which type of flap creates the greatest change in pitching moment? - Answer Fowler
AN airplane has a normal stalling speed of 60 knots but is forced into an accelerated stall at
twice that speed. What maximum load factor will result from this maneuver? - Answer 4 G's
If the airspeed increases and decreases during longitudinal phugoid oscillations, the aircraft? -
Answer Is maintaining a nearly constant angle of attack.
During a steady climb, the rate of climb depends on? - Answer Excess power.
The most desirable type of stability for an aircraft to possess is positive dynamic stability? -
Answer Positive dynamic stability.
A swept wing airplane with weak static directional stability and increased dihedral causes an
increase in? - Answer Dutch roll tendency.
The resistance, or skin friction, due to the viscosity of the air as it passes along the surface of a
wing is called? - Answer Profile drag.
Which type of flap creates the least change in pitching moment? - Answer Split.
The use of a slot in the leading edge of the wing enables an airplane to land at a slower speed
because it? - Answer Delays the stall to a higher angle of attack.
A line drawn from the leading edge to the trailing edge of an airfoil and equidistant at all points
from the upper and lower contours is called the? - Answer Mean camber line.
Which type of flap is characterized by large increases in lift coefficient with minimum changes in
drag? - Answer Fowler flap.
The purpose of aircraft wing dihedral angle is to? - Answer Increase lateral stability.
Consider only aspect ratio (other factors remain constant. Which aircraft will generate greatest
drag? - Answer The one with the lowest aspect ratio.
, Changes in the center of pressure of a wing affect the aircraft's? - Answer Aerodynamic
balance and controllability.
Which statement describes the relationship of the forces acting on an aircraft in a constant-
power and constant-airspeed descent? - Answer Thrust is equal to drag; lift is equal to
weight.
Which subsonic plan form provides the best lift coefficient? - Answer Elliptical wing.
A wing with a very high aspect ratio (in comparison with a low aspect ratio wing) will have? -
Answer A low stall speed.
Aspect ratio of a wing is defined as the ratio of the? - Answer Wingspan to the mean chord.
On which wing plan form does the stall begin at the wingtip and progress inward toward the
wing root? - Answer Sweep back wing.
Which aircraft characteristics contribute to s[spiral instability? - Answer Strong static
directional stability and weak dihedral effect.
An airplane leaving ground effect will? - Answer Experience a decrease in stability and a nose
up change in moments.
When rolling out of a steep-banked turn, what causes the lowered aileron to create more drag
than when rolling into the turn? - Answer The wing's angle of attack is greater as the roll out
is started.
Which relationship is correct when comparing drag and airspeed? - Answer Induced drag
varies inversely as the square of airspeed.
During flight with zero angle of attack, the pressure along the upper surface of a wing would be?
- Answer Less than atmospheric pressure.
A propeller rotating clockwise, as seen from the rear, creates a spiraling slipstream that tends to
rotate the aircraft? - Answer To the left around the vertical axis, and to the right around the
longitudinal axis.
