Systems/instruments

Question 1

2 types of ailerons

Answer 1

1. Differential: the aileron on the low side goes up more than the aileron on the high side goes down, in order to counteract adverse yaw
2. Frise type: when the aileron on the low side is raised, the low part of the surface protrudes downwards, creating more drag and countering adverse yaw

Question 2

Types of flaps

Answer 2

1. Single slotted
2. Simple
3. Split
4. Fowler

Question 3

Pre ignition vs detonation

Answer 3

Pre ignition: ignition of the fuel/air mixture prior to the full compression of the mixture
Detonation: uncontrolled and explosive detonation of the fuel air mixture

Question 4

2 types of carburetors

Answer 4

1. Float type
2. Pressure type

Question 5

Float type carburetor

Answer 5

-forces air through a Venturi, increasing speed and lowing pressure, pulling fuel in to mix with the air
-can have worse performance during maneuvers
-icing tendency

Question 12

What would happen to the ASI if the pitot tube is blocked?

Answer 12

Airspeed shows 0

Question 13

What would happen to the ASI if the pitot and drain hole were blocked?

Answer 13

ASI acts as an altimeter

Question 14

What would happen to the ASI if the static port is blocked?

Answer 14

-The altitude will stay the same at the same altitude
-the airspeed will show lower if you climb above
-the airspeed will show higher if you descend

Question 15

What happens to the ASI if the alternate static source is used?

Answer 15

Airspeed will read higher

Question 16

What happens to the altimeter if the alternate static source is used?

Answer 16

Altitude reads higher

Question 17

What happens to the altimeter if the static source is blocked?

Answer 17

Altitude freezes

Question 18

What happens to the VSI if the static source is blocked?

Answer 18

VS=0

Question 19

What happens to the VSI if the alternate static source is used?

Answer 19

Momentary increase, then settles down to the correct reading

Question 20

3 components of an oxygen system

Answer 20

1.storage
2.delivery
3.mask/cannula

Question 21

How can oxygen be stored?

Answer 21

As a gas, liquid, or solid

Question 22

3 types of oxygen delivery

Answer 22

1.continuous flow
2.diluter demand
3.pressure demand

Question 23

Continuous flow oxygen

Answer 23

Continuous flow of oxygen, even when you’re not breathing. 28,000 ft or lower

Question 24

Diluter demand

Answer 24

Delivers oxygen when you inhale, and stops when you’re not inhaling. Oxygen is diluted with cabin air. 40,000ft and above

Question 25

Pressure demand

Answer 25

Delivers oxygen through a forceful flow that over inflates the lungs. Above 40,000ft

Question 26

What needs to be done before using an oxygen system?

Answer 26

PRICE check Pressure Regulator Indicator Connections Emergency

Question 27

Time of useful consciousness

Answer 27

The period of time between when oxygen is cut off, to when the individual is no longer able to perform duties

Question 28

3 types of decompression

Answer 28

1.slow decompression 2.rapid decompression- a few seconds 3.explosive decompression- less than .5 seconds- the cabin decompresses faster than the lungs can
