ERJ 175 Oral SkyWest QUESTIONS &
ANSWERS|| 2025 LATEST UPDATE!!
What makes an airport a special airport? - ANSWER FAA administrator or SkyWest
designate an airport special if it has surrounding terrain, obstructions, or complex
approaches, Basically if it has a briefing pictures in the Jepp Charts labeled as airport
qualification
When do we need an alternate? - ANSWER 1-2-3 rule:
if within 1 hour before to 1 hour after ETA, the WX reports, forecasts, or any combo
indicate the ceiling will be less than 2000' above elevation, and/or visibility less than 3
miles
What is marginal weather? - ANSWER Destination: visibility at minimums.
Alternate: ceiling and visibility at minimums.
An airport with a METAR reports a ceiling lower than 2000' or 3 miles but the TAF does
not require an alternate. When would you need an alternate? - ANSWER on flights with
less than 1 hour time enroute
When do we need a second alternate? - ANSWER Weather at destination and alternate
is marginal OR
Using Exemption 3585, conditional language (TEMPO and PROB) forecast WX
conditions at the destination will not be less than 1/2 the lowest WX mins visibility
established for the instrument approach procedure expected to be used
When can you not use 3585? - ANSWER International destinations or high mins
captains
When do you need a takeoff alternate? - ANSWER When WX at departure airport is
below minimums.
Must be within 1 hour single engine normal cruise in still air
3585 not allowed
When you turn the batteries on, what do you look for? - ANSWER 22.5 volts or better
Describe the electrical PBIT - ANSWER It is performed anytime ac power is established
on the aircraft. It takes 3 minutes to complete and is good for 50 hours. It can be
interrupted 3 ways. By interrupting AC power, pushing any one of the 3 flight control
mode switches, by turning on a hydraulic pump
,Describe the Hydraulic PBIT. - ANSWER It is performed when all 3 hydraulic systems
are first pressurized. It takes 1 minute to complete and it is good for 50 hours. It can be
interrupted by moving a flight control
How long does the evacuation slide light battery last? - ANSWER 10 minutes
In an electrical emergency do the flaps still work? - ANSWER Yes, at a slower speed,
and they will only go to a max of 3 in order to provide adequate airspeed for the RAT
What are the 4 things you get back when the RAT powers the AC ESS BUS? -
ANSWER AC fuel pump 2
ACMP hyd pump 3A
1 channel of slats
1 channel of flaps
How do you get a green light on the nose gear? - ANSWER Parking brake off and main
brakes not applied steering switch in ext power panel must be in disengaged-- This will
also disengage the steering inside (steer off)
With an inop APU, why do we start the #2 engine first? - ANSWER The ground
connections for the ext power and high pressure air are on the left side of the plane
Which engine do we normally single engine taxi on and why? - ANSWER #1
system logic will turn on the #2 hyd pump with only the #1 engine running, whenever
the parking brake is released, and the pump knob is in auto. this will give us pressure to
the INBD brakes which are on sys 2.
Can we single engine taxi on the #2 engine? - ANSWER YES, by following a QRH
procedure which will have us turn on the #1 hydraulic pump to provide pressure to the
outboard brakes
Describe "HOLD" mode - ANSWER it deactivates the autothrottle servos between 60
kts and 400'. this is to "lock" in the takeoff thrust setting and also to prevent the
autothottles from increasing thrust during a rejected takeoff
What is Track mode? - ANSWER Track mode is used to intercept and maintain an
inertial derived airplane track from the IRS during Takeoff and Go around. It activates at
100kt and with bank less than 3 degrees on takeoff on a go around it activates when
TOGA button is pushed
What are the recommended climb, cruise and descent speeds? - ANSWER 250 kts
below 10,000 and what else? Look it up
Describe driftdown procedure. - ANSWER Allow autothottles to advance to TOGA
disconnect A/T verify "CON" adjust Alt selector to appropriate alt, (approx. 20,000')
according to QRH Set driftdown speed (green dot) LOOK IT UP TO BE SURE
, Why are we disarming the auto throttles on a driftdown procedure? - ANSWER We are
getting the thrust to CON (max continuous) we disconnect them to allow us to descend
in FLCH in Speed on Elevator and maintaining green dot i.e. a slow descent rate at max
power, stay as high as possible for as long as possible
What system powers the nose wheel steering? - ANSWER HYD 2
What happens when you push an illuminated cargo fire switch in flight? - ANSWER The
high rate bottle will discharge followed by the low rate bottle 1 minute later unless you
push it earlier
Will the low rate cargo bottle discharge automatically on the ground? - ANSWER No,
you must push the button again
Can you discharge the cargo bottles in flight without a fire msg? - ANSWER Yes, push
the button once to arm it, a second time to blow the bottles according to logic
Can you discharge the cargo bottles on the ground without a fire msg? - ANSWER Yes,
push the button once to arm it, a second time to blow the high rate bottle and a 3rd time
to blow the low rate bottle
What happens when you push the dump button in auto mode? - ANSWER
Packs and recirc fans turn off outflow valve climbs the cabin to 12,400' at 2000fpm at
12,400 the outflow valve closes and the cabin rises by natural leak - ANSWER
What happens if you push the dump button in manual mode? - ANSWER The packs
and recirc fans turn off only
When do we adjust for icing speeds? - ANSWER
How do you calculate Vap speed? - ANSWER Non-ice conditions Vref +5 min or take
1/2 steady state headwinds plus the full gust factor up to max of Vref + 20 ex. landing
rwy 36 Vref is 130 winds are 360@10 gusting to 20 Vap would be 145kts icing
conditions Vap would be min of Vref new +0 up to Vref new +20
How long for engine cool down? - ANSWER 2 minutes
How many batteries for the emergency lights how long will they last? - ANSWER 4
batteries, 10 minutes
Can you put out an engine fire with the airplane depowered? - ANSWER Yes, the fire
bottles are located on the hot battery buses
What type of engines do we have? - ANSWER GE CF34-8E
