21
Q

Why should rapid and large thrust lever changes be avoided?

A

It can be detrimental to engine components and accelerate engine deterioration.

22
Q

What can cause the autothrottles to completely retard and advance?

A

Large/excessive speed changes with the autothrottles engaged.

23
Q

how should excessive thrust lever movement be prevented (if it occurs) while operating on autothrottles?

A

overriding the thrust levers is preferrable to disconnecting the autothrottles

24
Q

If turbulent air can not be avoided, what are the best practices for penetration?

A

Reduce altitude to increase buffet margin, do not chase airspeed maintain attitude and do not use large inputs, after established, trim for penetration speed do not change trim control, the aircraft with the elevators, do not chase altitude;allow airspeed and altiude to vary MAINTAIN ATTITUDE

25
Q

Should the autopilot be used for flight in severe turbulence?

A

Yes

26
Q

What four items are required for flight in RVSM airspace

A
  • Transponder,
  • either primary altimeter system (CA or FO),
  • altitude alerting and capturing capability,
  • autopilot.
27
Q

what item is commonly and mistakenly thought of as being required for flight in RVSM

A

TCAS

28
Q

When can the autopilot be disengaged during level curise fight in RVSM airspace?

A

To retrim the aircraft or due to turbulence

29
Q

What is the minimum/recommeded holding conifguration/speed?

A
  • clean configuration
  • gear up
  • speed not less than green dot
30
Q

What is the Skywest minimum holdingt speed in icing conditions and out of icing conditions?

A
  • Icing conditions - Maximum endurance/210kias whichever is higher
  • Out of icing - not less than green dot
31
Q

Operation is severe icing conditions is?

A

PROHIBITED

32
Q

When may asymmetrical ice shedding (engine) be encountered?

A

operations in moderate to severe icing conditions

33
Q

Are operations in severe icing conditions approved/permitted?

A

NO

34
Q

What pilot action should be performed if operating in moderate to severe icing condiotions with regards to the engines?

A
  • reduce one thrust lever, at a time, towards idle
  • advance to 70% N1 for 10-30 seconds
  • then return thrust levers to position required for the conditions
  • procedure should be repeated every 15 minutes if fan ice build up is suspect (high indicated or percieved)
35
Q

During the engine ice shedding procedure what may happen

just prior to actual ice shedding and will not affect the engine?

A

vibration may peak to the maximum value

36
Q

Is the ERJ-175 certified/capable of flying in freezing rain/dizzle (SLD) conditions?

A

NO

37
Q

when in flight what cues would determine the aircraft is encountering severe icing conditons?

A

Abnormal ice formation on areas not usually affected or ice formation on a previouly treated upper surface of the wings; anytime the anti-icing system cannot keep the airplane clean.

38
Q

What indication represents the driftdown speed during OEI operations?

A

Green Dot

39
Q

what is the driftdown procedure?

A
  • AT off
  • operating engine thrust lever TO/GA
  • Verify thrust setting CON
  • set drift down altitude
  • set drift down speed (green dot)
  • reaching green dot speed select FLCH
40
Q

What typically causes unreliable airpeed indications?

A
  • Partial static system blockage
  • frozen moisture
  • damage
  • failing parts
41
Q

If the airspeed indication becomes unreliable, what AFCS components must be turned off?

A
  • AT
  • autopilot
  • flight director
42
Q

Should the FD be followed/trusted if airpeed indication becomes unreliable?

A

NO

43
Q

Use of speed brakes should be __________ when aispeed is unreliable

A

avoided

44
Q

During high altitude operations (RVSM airspace), what engine abnormalities may be encountered during high angle of attacks associated with airpeed deterioration and stall conditions?

A
  • surging
  • compressor stalls
  • loss of thrust
  • flame out
  • core lock
45
Q

When should the stall recovery procedure be intiated?

A
  • immediately recognizing stall condition
  • stick shaker activation
  • feeling stall buffet
46
Q

When the FBW system is operating in normal mode, setting the thrust levers to the MAX position will disconnect the ________and automatically retract the ___________?

A
  • autothrottle
  • speed brakes
47
Q

In normal mode, the high level functionalities of the FBW system, will__________?

A

automatically neutralize any pitch up tendency caused by adding thrust

48
Q

If the FBW system is reverted/operating in direct mode more_______

may be required to produce the same pitch change.

A

control column input

49
Q

When might an amber vibration indication be displayed on the EICAS?

A

At TOC, or cruise, at 0.78M and N2 at 84-89%

50
Q

If reducing speed, at cruise, with an amber engine vibration

EICAS message, does not clear the message what must be promptly accomplished?

A

applicable QRH procedure

51
Q

If engine vibration occurs under any circumstances other than the .78MACH scenario what must be accomplished?

A

QRH procedure
