List the Secondary Flight Controls:

List the three axes

The Primary Flight Control that rolls the aircraft is the _____________________.

The Primary Flight Control that pitches the aircraft is the _____________________.

The Primary Flight Control that causes the aircraft to yaw is the _____________________.

The pilot controls the aircraft’s primary flight controls with the _____________________ or _____________________ and the _______________________________.

Three mechanical methods of moving flight controls are:

The ____________________ is the curvature of the wing surface that generate _________________ .

The curvature of the wing surface creates a ____________________ pressure.

The ____________________ is an imaginary line from the leading edge of the wing, through its center, to its trailing edge.

The ____________________ is the distance from wing tip to wing tip.

The ____________________ is parallel and opposite to the flight path of the aircraft.

The angle of ________________ is the angle between the longitudinal axis of the aircraft and the ____________________ of the wing.

The angle of ________________ is the angle between the ____________________ of the wing and the ________________ of the wing.

A symmetrical wing creates lift by having a ________________ angle of ________________ as compared to an asymmetrical wing when it is installed on the aircraft.

The flaps are normally located on the ____________________ of the wing on small aircraft.

The purpose of flaps is to lower the ____________________ of the aircraft, thereby increasing the ____________________ during the approach to landing.

Flaps can be used to ________________ the take-off distance of an aircraft by ________________ the take-off speed.

When the flaps are extended, they increase ________________ and ________________.

Five types of flaps are:

Heavy aircraft may also have ________________ flaps that work in conjunction with ________________ flaps.

Other types of devices at the leading edge of the wing are ________________ and ________________.

Panels on the upper surface of the wings that disrupt lift are called __________ and __________.

When a stall occurs, the airflow over the wing __________ and decreases lift, thus causing the aircraft to pitch __________.

The opposing forces acting on an aircraft are __________ opposing __________ and __________ opposing __________.

In order for an aircraft to take off, __________ must overcome __________.

In straight and level flight (when the aircraft is neither accelerating nor decelerating, and neither climbing nor descending) all forces are said to be at __________.

The purpose of trim tabs is to __________, thereby assisting the pilot in controlling the aircraft.

On small aircraft, trim tabs are commonly found on the __________. They may also be located on the __________ and __________.

The purpose of a servo tab is to assist the pilot in controlling the __________ control surfaces and moves in the __________ direction of the surface.

The spring tab functions like a servo tab at __________, and has a spring attached to the tab to assist the pilot to move the control surface at __________.

An anti-servo tab moves in the __________ direction of the flight control surface and __________ the sensitivity the flight control.

An anti-servo tab is usually found on aircraft with a __________.

The balance panel uses __________ to assist the pilot move the control surface.

__________ are small devices that are installed on an aircraft to promote positive __________.

A __________ will prevent spanwise airflow.

__________ are installed on the wing’s inboard leading edge to stall the inboard section first, thereby allowing the __________ to maintain lateral control through the stall.

39. __________________________ can be used to maintain smooth airflow between fixed and moveable surfaces; thus, decreasing _______________.

40. __________________________ are located at the wingtips, and prevent the airflow under the wing from spilling over to the low pressure area on top of the wing.

41. The __________________________ combines the functions of an elevator and rudder.

42. The __________________________ combines the functions of an aileron and a spoiler.

43. The __________________________ combines the functions of an aileron and a flap.

Two types of stability an aircraft may exhibit is ____________________ and ____________________ stability.

45. ____________________ stability may be further divided into three categories:

46. ____________________ ____________________ stability is the tendency of an aircraft to gradually return to an equilibrium after being displaced.

47. ____________________ ____________________ is the tendency of an aircraft to increase its amplitude of motion with time when upset from equilibrium.

48. ____________________ drag is the resistance to airflow caused by the surfaces of the plane that are creating lift.

49. ____________________ drag is the resistance to airflow created by objects on the aircraft that are not creating lift. Three examples are:
