Interview
I interviewed in November. The advice to grab the gouge from aviationintervews.com is where I would go. Because you are probably looking for more than that, here is what I got:
HR:
● What do you know about Skywest? (Largest regional in the US, headquartered in Utah, operates for United, American, Delta, and Alaska, nearly 500 aircraft.)
● Why do you want to work at Skywest? (I've only heard good things about skywest: awards for best company to work for, forbes most admired company. People who work there say: fun people, good culture.)
Tell me about a time…
● You overcame a difficult situation using CRM?
● You had a disagreement with your captain?
● You had a disagreement with a coworker/ boss?
● You had an emergency while flying?
● You had to abort a flight/turn back?
● You saw someone do something unsafe?
Weather:
● Explain a microburst.
● Can you overfly a thunderstorm? (yes, by 1000ft for every 10kt of wind speed)
● Where is the most severe turbulence in a thunderstorm? (top third of the thunderstorm)
● What is needed for a thunderstorm to form? (high humidity, lifting action, unstable air)
● What is a lenticular cloud? (forms around mountains. Air moves over a mountain lowering its pressure and temp, forming a cloud. Air moves, cloud stays in place)
● What is hydroplaning? (a build up of water between the tires and surface which causes a loss of traction)
Jet Engines:
● Explain a Turbine Engine (Fan, compressors, combustion, turbines)
● What is a Compressor stall (Similar to wing stall, can happen with abrupt pitching. Recovery is to reduce AoA and reduce power)
● What is a Diffuser (slows down air before entering the combustion chamber)
● What is a Stator? (position airflow for the next compressor stage)
● What is a hot/hung start? (Hot start= Engine exceeds temperature limits during start. Hung Start = engine starts but at too low RPM)
● What is a PACK? (Pneumatic Air Cycle Kit, AKA air conditioning/Compressed air cooling)
General Systems:
● What is an inverter/rectifier? (Inverter converts DC to AC, Rectifier converts AC to DC)
● Where does bleed air come from? (compressor section of engine [hp and lp])
● What is bleed air used for? (anti-ice, pressurization, heating and cooling)
● Is bleed air cooled before entering the cabin? (yes, it goes through the PACKs and is mixed with hot air for temp control)
● Explain basic electric stuff (AC/DC, amps, volts, etc.)
● Tell me about the Navajo electrical system? (28 volts, powered by two 70 amp alternators. Battery is 24 volt 17 amp/hr.)
IFR:
● When is an alternate required for IFR? (within 1hr of ETA, wx must be at least 2000ft and 3sm.)
● When is a takeoff alternate needed? (when weather is below landing minimums for the departure airport. Alternate must be within 1hr cruise with 1 engine INOP)
● What is Exemption 3585 or 17347? (Ordinarily an aircraft operating 121 could not depart if wx at destination or alternate is below minimums. This exception allows the aircraft to depart if conditional language (prob, bcmg, tempo) indicates that weather will be at least ½ of minimums at the destination and/or first alternate. Using this exemption requires a second alternate that is forecast above alternate minimums.
● Can you depart if forecast weather is below landing minimums? (no, except exception above)
● What are derived alternate minimums? (Instead of using standard alternate minimums (600-2/800-2) airlines can create their own alternate minimums by using a table in their opspecs. If one approach is used, take the approach minimums and add 400-1, for double approach (separate approach, nav aid, and runway), add 200-½ to the higher minimums of the two approaches.
● When is a second alternate required? (A second alternate is required when forecast weather at the destination and first alternate is “marginal” definitions of marginal vary by carrier, however it usually means close to minimums.)
● Study Jepp Charts
● When can you descend below DA/MDA? (GATTR, glideslope lights, approach lights, threshold, touchdown zone, and runway markings lights or surface)
● What do you do if you lose comms under IFR? (Fly your route as accepted, vectored, expected, or filed, and the highest of the MEA, expected altitude, and assigned altitude. Fly to clearance limit, hold until ETA, proceed to fix to begin an approach)
Regulations:
● Holding speeds? (200 up to 6,000ft, 230 is 6,000ft-14,000ft, 265 above 14,000ft)
● Airspace speeds? (250 KIAS under 10,000ft. 200 KIAS within 4nm and 2500ft of class C or D, and under class B.)
● Max procedure turn speed? (200 KIAS)
● Where does RVSM start? (FL290)
● How many flight attendants are required? (1 per 50 pax)
Airport lighting/markings:
● Review approach light systems and markings
Aerodynamics:
● What are the advantages and disadvantages of a swept wing? (Pro: increased critical mach number due to reduced chord-wise flow. Con: reduced lift, poor yawing characteristics (dutch roll))
● Where does a stall start on a swept wing aircraft? (wingtips)
● Why can a swept wing plane fly faster? (it decreases chord-wise flow, which delays the formation of shockwaves.
● What is a dutch roll? (a dutch roll is a rolling and yawing oscillation)
● What is Mach Tuck? (After airflow around the wing goes supersonic, the center of pressure moves aft causing a pitch down. This increases airspeed and makes recovery difficult)
● What is coffin corner? (when the aircraft is close to Mmo and also its stall speed. This happens at high altitudes)
I had other co-workers interview around the same time, similar questions but a few differences.
