175 2020 CQ Flashcards
Why does the Emergency/Parking brake need to be on prior to starting external inspection?
Determine there is sufficient hydraulic pressure to activate the emergency/parking brake to check the Brake Wear indicators.
Just because the parking brake is on, does this guarantee that there is sufficient hydraulic pressure to check the Brake wear indicators?
No - you can look at the STATUS page and look at EMER ACCU pressures for SYS 1 and SYS 2.
If the hydraulic pressure is depleted for the brakes, how can it be restored prior to the external walkaround?
Pressurize Hydraulics.
On the external inspection, you notice that the air data smart probes are covered in frost. What would be an appropriate action by the pilot?
ADSP Heater Switch: ON.
Provide at least one other condition that would require heat being applied to the ADSPs during the preflight?
Spurious AFCS and/or ADS EICAS messages on power up.
Use the pictorial walk around - describe preflight action outlined in the SOPM for the Nose Landing Gear.
Wheel Chocks In, Condition of Wheels/Tires, Free of Snow/Ice, Up Lock Hook Unlocked, Condition of Downlock Springs, Condition of Strut/Wheel Well/Doors, Ground Locking Pin Removed, Condition of Landing and Taxi Light.
What unique piece of equipment resides in the right forward fuselage? Describe the SOPM external preflight of the RAT.
Ram Air Turbine. Stowed and RAT Safety Lock Pin removed.
What is the proper preflight action of the Engine Inlet according to the SOPM?
Basic condition, check for FOD and leaks inside air inlet. Ensure there is no damage to the T12 sensor and the FADEC cooling inlet is clear.
What is the proper preflight action of the Fan Blades according to the SOPM?
Check for damaged blades and ensure fan is free to rotate. Check for damage on spinner.
Are there Nacelle Strakes on both sides of the fuselage?
Yes - each engine has a left and right side nacelle strake.
How many magnetic level indicators do we have to inspect on each wing?
3 per wing.
Describe the main landing gear inspection according to the SOPM.
Clear of ice/debris/obstructions. Condition of Wheels/Tires. Up Lock Hook unlocked. Condition of Downlock Springs. Condition of strut/wheel wells - no leaks. Ground Locking Pin removed. Brake wear indicators checked.
How many static dischargers are on the aileron? Winglet? What document would you refer to regarding missing static dischargers?
3 aileron. 6 winglet. AFM/CDL.
You’re sitting at the gate when a BATT 1 OVERTEMP warning message appears. What do you do? How do you verify that this action was effective?
BATT 1»OFF. MEAN! Look at electrical synoptic to see if BATT 1 temperature is decreasing.
You’re starting an engine and notice that the ITT is rapidly rising toward the ITT redline. What temperature is redline and what do you do?
815C. AFFECTED ENGINE»START/STOP SELECTOR: STOP. MEAN!
On taxi to the runway, the airplane begins veering to the left aggressively. What might you do?
STEER DISC SWITCH»PRESS. Steer the airplane using differential braking and rudder. MEAN!
Shortly after takeoff, the cockpit starts filling with smoke. What do you do? Where is this procedure located in the QRH/what section?
OXYGEN MASKS»DON, EMER
CREW COMMUNICATION»ESTABLISH
PRESSURIZATION DUMP»PUSH IN
Non-annunciated section. MEAN!
You’re flying in cruise at FL350 when you hear the triple chime and see CABIN ALTITUDE HI on the EICAS?
OXYGEN MASKS»DON, 100%
CREW COMMUNICATION»ESTABLISH
Plan for emergency descent… MEAN!
You’re flying in cruise when the autopilot disconnects and the airplane begins to pitch up, in spite of nose down control pressure. What do you do?
A / P DISC BUTTON»PRESS AND HOLD
PITCH TRIM SYS 1 & 2 CUTOUT BUTTONS»PUSH IN
MEAN!
Where is the battery temperature read? Give another example of why it is always important to view the appropriate synoptic page when troubleshooting a problem.
Electrical synoptic page. Flight control problem - look at flight control synoptic.
What CAUTION message will populate when the associated battery is selected off?
BATT 1 OFF or BATT 2 OFF.
List four of the seven conditions that require the pilot to manually abort the start.
NNoTM*/HHN
- No oil press within 10 sec after N2 increase.
- No N1 increase at starter cutout (~50% N2) when starting with a tailwind.
- No ITT within 30 sec of start (no light off).
- ITT exceeds 815C (hot start)
- No N1 increase at starter cutout (~50% N2) when starting with a tailwind.
- Oil Pressure stabilizes not in the green range.
- N1 or N2 fail to accelerate to stable (hung start).
- Oil Pressure stabilizes not in the green range.
- Intermittent elec or pneu or starter Malfunction before starter cutout.
Will the CABIN ALTITUDE HI likely result in a descent? What altitude will you descend to? How would you find MEA?
Yes. 10,000’ or lowest MEA. Jepp or ask ATC.
What action does the SOPM require when the cabin altitude reaches 14,500’ on an emergency descent?
MASKS DEPLOY selector knob to OVRD.
How must the MFD be configured for an emergency descent?
Select TERR on an MFD.
Is the pitch trim runaway addressed by the QRC? In what section of the QRH is it located?
Yes. Non-annunciated.
How would you alleviate excessive pitch up tendencies with a pitch trim runaway?
Shift the lift vector - roll the airplane.
When powering up, what min voltage is required? When would you need to perform the SOPM charging procedure?
22.5V…if less, go to SOPM. (If below 21V, then maintenance.)
After the EICAS is powered, how long must you wait before starting the APU?
30 seconds.
Can takeoff/landing occur with the FUEL IMBALANCE EICAS message.
Yes, as long as actual imbalance less than 794 lb.
What is the minimum fuel tank temperature?
-37C
What is the starter cranker limit for start attempts 1 and 2 (ground)?
90 seconds on (10 seconds off).
What is the minimum time between start attempts 1 and 2 (ground or flight)?
10 seconds off.
How do the starter cranking limits change in flight?
Longer - 120 seconds on. More airflow, more time allowed to get your engine going!
During an engine start, we must see N1 rotation by what N2?
Starter cutout at ~50% N2.
A taxiway is NOTAM’d closed to aircraft with wingspan over 100’. What is the wingspan of the 175?
93’11”
What is the maximum tailwind for takeoff?
15 kts
Are static takeoffs recommended with a crosswind component greater than 30 kts?
No.
What is the minimum runway width allowable?
100’
ATC reports moderate and possibly greater turbulence ahead. What’s turbulent air penetration speed? Is it a target or a maximum speed?
250 below 10 or 270/.76. Normally it is more comfortable to slow when encountering turbulence. In some cases it may be necessary to accelerate to turbulent air penetration. This speed provides a margin between stall and structural damage.
Flight through severe turbulence must be avoided. When not possible, reduce altitude to
increase buffet margin.
