F-control 2

Question 1

secondary flight control surfaces

Answer 1

help in deflection of primary surfaces.

Question 2

Types of Secondary Flight controls

Answer 2

• Flaps
• Leading Edge Devices
• Spoilers
• ## Trim Systems

Question 3

Flaps

Answer 3

help your wing adapt to your current phase of flight

Question 4

Flaps Functions

Answer 4

Extending your flaps increases lift,
and allows you to fly at slower
speeds.

Retracting flaps reduces
lift, and in turn, decreases drag.

Question 5

how Flaps work

Answer 5

flaps increase the
camber (and sometimes the area)
of your wing. By increasing the
camber of your wing, you also
increase the amount of lift your
wing can produce. With flaps
down, your wing can produce
more lift at slower speeds, than
when your flaps are retracted.

Question 6

Flaps advantages

Answer 6

• You can produce more lift, giving you lower takeoff and landing speeds
• You can produce more drag, allowing a steeper descent angle without increasing your airspeed on landing
• You can reduce the length of your takeoff and landing roll

Question 7

Types of Flaps

Answer 7

Split Flap

Slotted Flap

Fowler Flap

Plain Flap

Question 8

Plain Flap

Answer 8

The most simple flap

They hinge to the back of the
wing, and they pivot down when you
extend them

Question 9

Fowler Flaps

Answer 9

Type of slotted flaps

This flap design not only
changes the camber of the wing, it
also increases the wing area

Question 10

Split Flap

Answer 10

is deflected from the lower surface of the airfoil and produces a slightly greater increase in lift than the plain flap

Question 11

Slotted Flaps

Answer 11

most popular flap on aircraft
today

It increase the lift coefficient significantly
more than plain or split flaps

Question 12

High-lift devices

Answer 12

also can be applied to the leading edge of the airfoil

Question 12

Leading Edge Devices

Answer 12

Movable Slat

Fixed Slot

Leading Edge Cuffs

Leading Edge Flaps

Question 13

Slat

Answer 13

It is a portion of the
leading edge that moves down
and forward when it is
deployed, opening a slot
behind it and increasing the
camber of the leading edge.

Question 14

Fixed Slots

Answer 14

direct airflow to
the upper wing surface and
delay airflow separation at
higher angles of attack.

Question 14

Slot

Answer 14

is a adjustable opening
between either the leading
edge of an aileron and the rest
of a wing or the leading edge
of a wing and a cap fitting
over it.

Question 15

Movable Slats

Answer 15

It consist of leading
edge segments that move on
tracks

Question 16

Leading Edge Flaps

Answer 16

are used to increase both CL
MAX and the camber of the wings.

is frequently used in conjunction with
trailing edge flaps and can reduce the
nose-down pitching movement
produced by the latter.

Question 17

Leading Edge Cuffs

Answer 17

Like leading edge flaps and trailing edge
flaps are used to increase both
CL-MAX and the camber of the
wings

Question 18

Leading Edge Cuffs

Answer 18

are fixed aerodynamic
devices unlike leading edge flaps

Question 19

Spoilers

Answer 19

They are deployed from the
wings to spoil the smooth airflow,
reducing lift and increasing drag.

Question 20

Trim Systems

Answer 20

are used to relieve the pilot of the need to maintain constant pressure on the flight controls, and usually consist of flight deck controls and small hinged devices attached to the trailing edge of one or more of the primary flight control surfaces

Question 21

Trim Systems

Answer 21

Trim Tabs

Balance Tabs

Servo Tabs

Ground Adjustable Tab

Anti Servo Tab

Adjustable Stabilizer

Question 22

Trim Tabs

Answer 22

Are small adjustable surfaces on the control surfaces (like the elevator, rudder, or ailerons) that help maintain a desired flight attitude without constant control input from the pilot. They reduce pilot workload and improve flight stability.

Question 23

Balance Tabs

Answer 23

They look like trim tabs, but they have one major difference: balance tabs are attached to the control surface linkage, so when the control surface is moved in one direction, the balance tab moves in the opposite direction.

Question 24

Servo Tabs

Answer 24

Is a small portion of a flight control surface that deploys in such a way that it helps to move the entire flight control surface in the direction that the pilot wishes it to go

Question 25

Anti Servo Tabs

Answer 25

they move in the same direction as the trailing edge of the stabilator.

Question 26

Adjustable Stabilizer

Answer 26

is a tail surface that can change its angle to help control pitch and maintain balance during flight. It's often used to reduce drag and improve trim efficiency, especially in larger or high-speed aircraft.

Question 27

Ground Adjustable Tabs

Answer 27

This tab is bent in one direction or the other while on the ground to apply a trim force to the rudder.
