Flaps

Question 1

During take off which degree of flap setting is the best?

Answer 1

10 degrees to 20 degrees

Question 2

do all airplanes manufacturers recommend the use of flaps during take offs?

Answer 2

No

Question 3

When can flaps be used for take offs?

Answer 3

with an airplane that has sufficient take-off power to overcome the extra drag that extended flaps produce

Question 4

Do flaps increase drag?

Answer 4

yes

Question 5

What happens when you bring the flap down?

Answer 5

the more you bring the flap down the more drag you create

Question 6

How far can most flaps be extended to from the chord of the wing?

Answer 6

most flaps can be extended to 40 degrees

Question 7

What is the setting of the degree flaps can be set to

Answer 7

20 degrees to 40 degrees

Question 8

What is an essential function of the flaps?

Answer 8

to improve landing capabilities

Question 9

How does flaps improve the landing capabilities?

Answer 9

1) steepening the glide without increasing the glide speed

2) Permit slower landing speed and act as brakes when the airplane is rolling to a stop after the landing

Question 10

How does flaps help with safety of the plane?

Answer 10

1) less wear on undercarriage, wheels, and tires

2) speeds reduce possibility of ground looping during landing roll

Question 11

What does plain and split flaps increase?

Answer 11

they increase lift of the wing but at the same time they also increase drag

Question 12

When are plain and split valued and why?

Answer 12

Only when approaching to land because the extra-drag when taking off reduces acceleration

Question 13

what 2 types does the slotted flaps include?

Answer 13

1) Fowler Flap

2) Zap Flap

Question 14

what are slotted, fowler, and zap flaps used for and why?

Answer 14

used for take-off because produce lift in excess of drag

Question 15

what is the fowler flap most considered for?

Answer 15

Offer the most advantages and the fewest disadvantages.

Usually used on bigger planes

Question 16

What is the double slotted flaps most considered for?

Answer 16

smaller airplanes

Question 17

What does STOL stand for?

Answer 17

Short-take-off and landing

Question 18

What are the best flaps for when an airplane is doing a STOL?

Answer 18

combination of double slotted flaps and leading edge flaps

Question 19

What happens when the flaps are lowered?

Answer 19

the C.P moves rearward creating a nose down (pitching moment)

Question 20

What happens to the airplanes that has a change in airflow over the tailplane when flaps are lowered?

Answer 20

it creates a nose up therefore it is necessary to trim the nose down

Question 21

what is the maximum flap extended speed?

Answer 21

it is the maximum speed that a flap must not be lowered which is displayed in most airplanes

Question 22

When should the flaps raise when the airplane is coming in for landing?

Answer 22

The flaps should not be raised until the airplane is on the ground

Question 23

When should you bring the flaps back up if the airplane misses the landing?

Answer 23

Should not raise the flaps until the power has been applied and the airplane has regained normal climbing speed.

Raise flaps in stages

Question 24

How much flap should be used when landing?

Answer 24

for the purpose of safety should use the FULL FLAPS

Question 25

when landing what are the 2 effects the flaps has on the wing airfoil?

Answer 25

both lift and drag are increased

1) lift results in a lower stalling speed and allows a lower touchdown speed
2) drag allows a steeper approach angle without increasing airspeed. Extra drag results in shorter landing roll

Question 26

What are the factors of the procedure of using full flaps?

Answer 26

1) Airplane gross weight
2) Position of the centre of gravity
3) approach to landing
4) wind conditions
