72
Q

What causes clear air turbulence?

A

Jet Stream, 2 different bodies of air moving against each other

73
Q

How does a High-Bypass Turbofan Engine operate?

A

Air is sucked in from a large fan in front. From there the air splits into the bypass air and the air that will go through the engine core. As the air enters the engine core it will go through a Low Pressure Compressor, then a High Pressure Compressor. From the High Compressor stage its directed to the Combustion Stage where the air will expand and mix with fuel for ignition. That energy is captured by the next 2 stages of turbines, the High Pressure and Low Pressure turbine (in that order). These turbines are connected to the compressors up front respectively (high turbine to high compressor N2, and Low Pressure Turbine to Low Pressure Compressor N1). Leaving the turbines, the air is rejoined with the bypass air and blown out the back of the engine.

74
Q

How much thrust comes from bypass air?

A

Roughly 80%

75
Q

What is bypass air and what is the benefit?

A

Typically bypass air makes up 80% of the air that is sucked into the engine (turbofan). Bypass air flows between the core of the engine and the outside casing. The benefit of using so much bypass air is both fuel efficiency and it’s quieter than a full-on jet engine.

76
Q

Where does the bleed air come from?

A

High Pressure Compressor blades (N2)

77
Q

What is used from the engine’s bleed air?

A

Engine and wing thermal anti-ice, also used for pressurization, heating and cooling

78
Q

How does a jet engine starter work?

A

Jet engine starters function by spinning the compressor, usually from an AGB, to a sufficient speed that allows the intake of air, compressing it and mixing it with fuel. Once ignited, this mixture generates thrust. This process can be done pneumatically, using high pressure air, or electrically with a starter generator

79
Q

What are some Turbofan start malfunctions?

A

Hot start, Hung start, and No Light Off

80
Q

What is an Engine Hot Start?

A

When EGTs exceeds limitation, mainly due to low airflow moving through the engine and thus not allowing for sufficient cooling to occur during start up

81
Q

What can cause an engine hot start?

A

Hot temperatures and high density altitudes. Weak starter, low electric currents from batteries/APU are all reasons for a hot start

82
Q

What should you do if you suspect an engine hot start?

A

Cut fuel immediately and then refer to the aircraft POH

83
Q

What is an Engine Hung Start?

A

When the engine RPM does not accelerate past the IDLE speed and “hangs”

84
Q

What can cause an engine hung start?

A

Usually due to low airflow in engine not allowing the N2 compressors to begin turning fast enough to accelerate engine past IDLE

85
Q

What should you do if you suspect an engine hung start?

A

Shut down engine and refer to aircraft POH

86
Q

What is an Engine Wet/No Light Off Start?

A

Fuel is being pumped into combustion chamber but no ignition is happening resulting in a flooded combustion chamber

87
Q

What can a wet/no light off start do to the engine?

A

With an excess amount of fuel in the combustion chamber, if ignition were to light, would cause a mini explosion and thus damaging the engine

88
Q

What should you do if you suspect an engine wet/no light off start?

A

Cut fuel immediately and refer to aircraft POH

89
Q

How do you convert AC to DC and DC to AC?

A

AC to DC requires a Rectifier
DC to AC requires an Inverter

90
Q

What is a better form of electricity and why?

A

AC due to it being more lightweight and safer in use with the ability to increase voltage by a transformer and an overall decrease in current. Less power is loss when transmitting across longer distances

91
Q

What is the flow of electricity?

A

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire

92
Q

What is a WATT?

A

Amount of power an electrical device consumes

93
Q

What is a VOLT?

A

Measure of electrical potential

94
Q

What is an OHM?

A

Measure of resistance in an electrical circuit

95
Q

What is an AMP?

A

Measure of the amount of electricity running in the circuit

96
Q

What type of power does the alternator produce? What type of power does the battery produce?

A

Alternator produces AC , battery produces DC

97
Q

What is an APU and how does it work?

A

AN APU is a small gas powered turbine engine normally located in the aft fuselage and is isolated from the cabin by a firewall. In flight, the APU is a back-up source of power for the generators. On the ground, the APU provides power for lighting, heating, cooling, cockpit avionics, hydraulic pressure, and main engine starting

98
Q

What is the purpose of a stator vane in an engine?

A

To properly position airflow to enter the next level of compression and to create a pressure increase of air by slowing the movement of the air

99
Q

What is the difference between the N1 and the N2?

A

N1 = the speed of the fan/low pressure compressor and low pressure turbine. N2 = the speed of the high pressure compressor and high pressure turbine

100
Q

Why is performance better in cold air than hot air?

A

Because cooler air is more dense

101
Q

What is a PACK?

A

Pressurization Air Conditioning Kits

102
Q

Why do you want to work for SKW?

A

3 things:
Their motto closely follows my motto… Safety First
QoL with no furloughs and great bases/advance aircraft (cultural and financial stability)
The reputation that SKW has built up through the industry. Some of the best training in the industry (legacy carriers love flying with SKW pilots)

103
Q

How do you mitigate risk and practice CRM on a typical flight?

A

Closed Loop Communication (the person receiving instruction or information repeats it back to make sure the message is understood correctly, and the sender confirms to “close the loop”)

103
Q

What is your biggest weakness?

A

Being able to admit my weaknesses. I am not as confident as I should be at times. When I don’t fully understand certain events, I may feel that I am not allowed to share my insight since I possess less experience on the subject

Antidote: There are rules and regulations as well as SOPs that provide me with the proper knowledge to lower my inexperience and always questioning when I do not fully understand something is how I have been helping to mitigate that weakness

104
Q

Where do you see yourself in 3-5 years?

A

Captain at SKW or even a Check Airman or someone on the training department team

105
Q

Describe your career in 3 minutes or less…

A

Exciting, Rewarding, and Passionate for what I do

106
Q

What do you enjoy doing outside of aviation?

A

Spending time with my wife and kids, exploring the Utah outdoors, and aquascaping

107
Q

A
108
Q

Have you ever broken a FAR?

A
109
Q

What qualities do you bring to the table that benefit SKW?

A

Paying it forward! Leaving something better than you found it

110
Q

What characteristics about SkyWest from the overview resonated with you the most?

A

Homegrown, honest company with some of the best training in the industry

111
Q

What are your ATP minimums?

A

1000 hour restricted ATP
- 200 XC
- 75 Instrument
- 100 Night

112
Q

Are you familiar with SKW guiding principles? Which one resonates best with you?

A

Mention how important I thought the statement that was listed on top of the guiding principles was (that SkyWest appreciated the precious commodity of time and quality of life). I believe that if you take good care of your people, they will take care of you

113
Q

What is an auxiliary gearbox?

A

The accessory gearbox is generally driven by the N2 shaft (connecting the high-pressure turbine to the high-pressure compressor) and in turn drives the engine accessories such as generators, hydraulic pumps, oil pumps, etc.
