SkyWest interview Questions and Answers 100% correct

SkyWest interview Questions and Answers 100% correct Describe Mach Tuck -Result of an aft ward shift in the center of lift causing a nose down pitching moment due to two reasons. 1) Shockwave induced flow separation, which normally begins near the wing root, causes a decrease in the downwash velocity over the elevator and produces a tendency for the aircraft to nose down 2) Aft ward movement of the center of lift, which tends to unbalance the equilibrium of the plane in relation to its CG in subsonic flight Dutch Roll -A combination of rolling and yawing oscillations that normally occurs when the dihedral effects of an aircraft are more powerful than the directional stability. Usually dynamically stable but objectionable in an airplane because of the oscillatory nature.

Diode -Two element electrical device that allows current to travel in one direction only. -Sometimes thought of as an electronic check valve Solenoid - An electromagnetically operated switch with a moveable core. Used to operate a variety of devices including switches, valves, and electromechanical devices Gearbox accesory -Part of Turbofan engine, not apart of the core -Driven by the N2 shaft (connecting the high-pressure turbine to the high pressure compressor) -Turns accessories such as generators, hydraulic pumps, oil pumps Critical Mach -Lowest Mach number at which the airflow over any part of the aircraft reaches the speed of sound -flight speeds greater than critical Mach will cause a dramatic increase in total drag and changes to the airflow over control surfaces leading to deteriorating control of aircraft Where is bleed air drawn from -Auxiliary power unit (APU) or another operating engine -Compressor section of engine Uses for bleed air -Pressurization of cabin -Air conditioning -engine start -Wing and engine anti-ice systems -water system pressurization -Hydraulic system reservoir pressurization -boundary layer separation enhancement AC and DC power in aircraft -Primary power generation is normally AC with one or more Transformer Rectifier Units(TRU) providing conversion to DC voltage to power the DC buses AC power -alternating current -AC can be transmitted over long distances more readily and more economically than DC since AC voltages can be increased or decreased by means of transformers. DC Power -direct current SkyWest CEO -Chip Childs How long does a TAF tempo line last -Expected to last for generally less than an hour at a time -Are expected to occur during less than half the time period How long is a TAF valid for 24 or 30 hours depending on the TAF Airspeed inside of and below a class B airspace -Below, 200 kts -Inside, 250 below 10,000 feet Max airspeed inside class B above 10,000 feet -Unrestricted Max airspeed inside a VFR corridor -200 kts Do you have to accept a LAHSO -NO Are you allowed to go around after accepting a LAHSO -A LAHSO clearance does not preclude a rejected landing -YES What is a critical engine The engine that when failed, it will most adversely affect the performance and handling capabilities of a multi-engine aircraft. What makes it the critical engine -PAST - P-Factor -Accelerated slip stream -Spiraling slip stream -Torque V1 -Speed by which time the decision to continue flight if an engine fails has been made. -Commit to fly speed V2 -Speed at which the airplane will climb in the event of an engine failure -Takeoff safety speed Vrot -Rotation speed is defined as the speed at which the aircraft attitude is increased Vmc -Minimum controllable airspeed with one engine operative Vlof -Lift off speed is the speed at which lift off actually occurs What happens to air temperature as it goes through the compressor -Temperatures increase from being compressed Where does bleed air come from and why different stages -Comes from the compressors -Taken from different stages because the aircraft might require some air to be of different temperatures and pressures What is a compressor stall -angle of attack of the blades of the compressor exceed their critical angle of attack resulting in one or more stages of rotor blades failing to pass air smoothly to the succeeding stages What is coffin corner or Q corner -The edge of an aircrafts high altitude operating envelope, marked by the speed margin between the high speed buffet and low speed buffet. -At very high altitudes this difference may be just a few knots and might disappear altogether for certain aircraft. -A small increase in bank angle or turbulence could induce a stall that may be unrecoverable. -Descend to a lower flight level. If you see the ALS can you land Yes if you can see the red terminating bars or side row bars When can pilot descend below MDA or DH? a) aircraft continuously in position from which descent to landing on intended runway possible with normal rate and maneuvers b) flight visibility not less than those prescribed in standard instrument approach procedure being used c) at least one of the following visual references is visible and identifiable: - approach light system (ALS), but not able to descend below 100 ft unless red terminating bars or red side row bars are visible - threshold - threshold markings - threshold lights - REIL - VASI - touchdown zone markings - touchdown zone lights - runway and runway markings - runway lights What is the highest point on the planview of an approach chart -Bold black arrow Amps vs Volt -An amp is simply the amount of electricity used by an item -A volt is the measure of the pressure that allows electrons to flow When is a takeoff alternate required and distance required for alternate -When the weather at the departure airport is below lowest usable landing minimums -Aircraft having 2 engines: not more than one hour from departure airport at normal cruising speed in still air with one engine inop Describe an air molecule through a turbofan -80% of air goes into the bypass around the engine. The other 20% goes inside the inlet to the core. -The inlet feeds to different stages of the compressor speeding up the air with rotating blades and stator veins. -From there the compressed air is pushed into the combustor where the engine is igniting the fuel and air mixture. -After the combustor the exhaust air is pushed through a turbine and then pushed out the nozzle Explain the 3-2-1 Rule -You always need an alternate unless —weather need to be at least 3sm vis 2000 feet ceilings 1 hour before and after your planned eta IFR fuel requirements -Departure airport>Destination>Alternate>45 mins at cruise Holding speeds Min hold alt - 6000'.........200 KIAS 6,001 - 14,000'.....................230 KIAS * Above 14,000'.....................265 KIAS Describe continuous Ignition -Automatic and pilot selectable activation of the ignition system in circumstances other than during the start cycle. -Usually turned on during takeoff, landing, and significant turbulence/precipitation. What turns DC power into AC Inverters What is the purpose of a circuit breaker -The purpose of a circuit breaker is to open the circuit when an overload exists. What does the number on a circuit breaker represent Specified amperage at which it will pop Describe an embedded thunderstorm -Thunderstorm embedded or obscured by cloud layers or haze How far should you avoid thunderstorms -At least 20 miles -Do not fly under anvil What is Virgo -Rain that evaporates before reaching the ground -Can carry hazardous downdrafts and/or icing conditions Describe hold over time -Estimated period for which anti-icing or deciding fluid will prevent the accumulation of ice, snow or frost on the aircraft What provides heat for anti-ice systems -In most turbine powered aircraft engine bleed air is commonly used to supply the required heat. -Piston aircraft will commonly rely on electrical power to supply heat Describe Vy -Vy is the speed that will allow an aircraft to gain the most amount of altitude in the least amount of time Describe Vx -Vx is the best angle of climb. -Speed at which an aircraft achieves the greatest gain in altitude for a given distance over the ground. VFR lost comm procedures -Squawk 7600 -Expect light gun signals if going to tower -No tower, fly 1,000 feet above TPA Tell me about yourself Why SkyWest What does a Yaw Dampener do -Essentially acts like an automated set of feet on the rudders inhibiting the aircraft around its vertical axis -Inhibits Dutch roll tendency Visual cues of which way a thunderstorm is moving -Anvil will be stretched out with the higher level winds. -Could also potentially use slant of the rain if visible When do you need to hold short of the ILS critical area -When instructed to do so by tower -Ceiling less than 800 feet or vis less than 2 miles Name the three stages of a thunderstorm -Cumulus -Mature -Dissapating Describe a hung start -Normal light off yet engine RPM remains at a low value rather than increasing to the normal idle speed. -Often the result of insufficient power to the engine from the starter. -Immediate shut down Describe a hot start -Normal engine rotation occurs but with exhaust temperatures exceeding prescribed limits, usually caused by an excessively rich mixture in the combustor -Fuel to the engine must be termintated immediately to avoid damage Weather expected with a cold front As the front passes expect -towering cumulus or cumulonimbus -Heavy Rain -lighting, thunder and or hail -tornadoes -low visibility -Winds variable and gusty -Temp and dew point, barometric pressure to drop Weather expected with a warm front As the front passes expect -Stratiform clouds -drizzle -Low ceilings -poor visibility -variable winds -rise in temperature What is standard temperature and pressure -15c -29.92 Hg What's an Isobar -Line of equal or constant pressure What factors must be present for a thunderstorm to form -Sufficient water vapor -An unstable lapse rate -An initial upward boost (lifting) to start the storm process in motion. Do you have anyone who influences you? Johnny Kim. Navy seal, Harvard Md, nasa astronaut. Where do you see yourself in 3-5 years Captain at SkyWest ideally also involved in the training department or legacy carrier. Would be happy with both Why SkyWest I heard a lot about how First Officers are captains in training; This is the mentality that I want to especially adopt going through training and out into the flight line, because the learning never stops On top of that I have a couple friends that fly here and they all love it
