46
Q

an instrument that measures the height of
an aircraft above a given pressure level.

A

47
Q

indicates whether the aircraft is climbing,
descending, or in level flight. The rate of climb or descent is
indicated in feet per minute (fpm).

A

vertical speed indicator

48
Q

sensitive, differential pressure gauge that
measures and promptly indicates the difference between pitot
(impact/dynamic pressure) and static pressure.

A

airspeed indicator

49
Q

Any spinning object exhibits gyroscopic properties. A wheel
or rotor designed and mounted to utilize these properties is
called a gyroscope.

A

gyroscopic

50
Q

is mounted
at an angle, or canted, so it can initially show roll rate. When
the roll stabilizes, it indicates rate of turn.

Q

When a body is
acted upon by a constant force, its resulting
acceleration is inversely proportional to the mass of the
body and is directly proportional to the applied force.

tends to remain at rest, and a body in motion tends to
remain moving at the same speed and in the
same direction.

A

newtons first law

64
Q

Whenever one body
exerts a force on another, the second body always
exerts on the first, a force that is equal in magnitude but
opposite in direction.

It is usually rounded to minimize air resistance and smooth the airflow over the surface.

A

leading edge

66
Q

The rear edge of the airfoil where the airflow over the upper surface meets the airflow over the lower surface.
Typically, it is sharp to allow for a smooth exit of air and to reduce drag.

A

trailing edge

66
Q

A straight line connecting the leading edge to the trailing edge.
The length of this line is called the chord length and is a fundamental dimension in airfoil geometry.

A

chordline

67
Q

The curvature of the airfoil’s upper and lower surfaces.
measured as the maximum distance between the chord line and the mean camber line (a line equidistant from the upper and lower surfaces).
has a curved shape, usually with the upper surface more convex than the lower surface, enhancing lift.

A

camber

68
Q

since the downward deflected, aileron produces more lift as evidenced by the wing rising, it also produces more drag.
