Q

What will occur if landing at a flap setting of 20 degrees or less and the GPWS/GND SPLR FLAP ORIDE switch is not selected to ON?

A

The EGPWS will announce “TOO LOW FLAPS / TOO LOW TERRAIN” and the ground spoilers will not deploy on wheel spin up.

The ground spoilers will deploy when WOW switch shifted to ground mode.

Q

If the automatic HOPS senses a difference between the elevator input and the output and activates, what effect will it have on the elevator?

A

With the loss of all hydraulic power to the elevator, high control pitch forces will result. Use of elevator trim is required for pitch control.

18
Q

What switches must be selected ON to perform a stall barrier test?

A

Stall barrier switch on the center pedestal, and AOA probe heat on the overhead panel

19
Q

How many static wicks can be missing from the wings?

A

All static dischargers may be missing if ADF, LORAN, and HF communications are not required. If they are required, then no more than one from each wing may be missing. Reference CDL

20
Q

How many static wicks can be missing from the tail?

A

All static dischargers may be missing if ADF, LORAN, and HF communications are not required. If they are required, then no more than one from each wing may be missing. Reference CDL

21
Q

What is the maximum deflection of the ground spoiler panels?

A

55 degrees

22
Q

How are the ground spoilers normally activated (if armed)?

A

Wheel spin-up > 47 knots, or weight on wheels

23
Q

Where is the aileron trim tab located?

A

On the left aileron

24
Q

What is the purpose of the GPWS/GRD SPLR FLAP ORIDE switch?

A

When landing with less than full flaps, the switch allows ground spoilers to deploy (when armed) with wheel spin up in addition to eliminating the “TOO LOW FLAPS / TOO LOW TERRAIN” audio warning depending on AC speed, 159 kts or faster

25
Q

What will happen if the power levers are advanced for takeoff with the GPWS/GROUND SPLR FLAP ORIDE switch ON?

A

A red “Aircraft Configuration” cas message will illuminate

26
Q

What is indicated by a amber “Speed Brake Extended” cas message?

A

The speed brakes are extended with the power levers above IDLE

27
Q

Can the stall barrier switch be selected OFF in flight?

A

No, however in the event of a faulty stall barrier system, Stall Barrier Switch is selected OFF until the faulty system CB is pulled.

The switch will be selected ON for the operative stall barrier system to provide protection for the remaining of the flight.

28
Q

While performing the stall barrier test, what does the auto-pilot disconnect button do if held in?

A

Deactivates the stick pusher, the stick shaker is still active.

29
Q

While performing the stall barrier test, at what AOA do you expect the stick shaker and stall barrier to activate?

A

Stick shaker will activate at AOA of 0.85 followed 1/2 second later by the stick pusher which activates at AOA 1.0 units

30
Q

How do you know if the PITCH TRIM and YAW DAMP are engaged?

A

The switch capsule lights are extinguished

31
Q

If a hard-over is sensed in one elevator actuator, will only the affected elevator be shut off or will both actuators be shut off?

A

Only one

32
Q

If a hard-over is sensed in one aileron actuator, will only the affected aileron be shut off or will both actuators by shut off?

A

Both

33
Q

If a hard-over is sensed in one rudder actuator, will only the affected rudder be shut off or will both actuators be shut off?

A

Only one normally

34
Q

Is there an automatic hard-over protection for the spoilers?

A

No, in the event of a spoiler hard-over deflection, check the lateral control switch is OFF

35
Q

What is the minimum speed with the yaw damper inoperative above 20,000 ft?

A

210 knots

36
Q

What is the minimum speed with the yaw damper inoperative below 20,000 ft?

A

It is a function of fuel quantity, in accordance with the table in the Yaw Damper Failure checklist

37
Q

The Vref speed that is shown in the display controller is based on what flight control configuration?

A

Flap handle position

38
Q

In the event the landing gear handle will not come up after takeoff, followed by and amber WOW FAULT and red GROUND SPOILER cas message, what action should be taken immediately?

A

Turn OFF the ground spoilers

39
Q

What must be done in order to manually trim the elevator?

A

Turn the pitch trim switch OFF

40
Q

What are the maximum speeds for flaps 10, 20 and 39 (full down)?

A

250 kcas - 10
220 kcas - 20
180 kcas - 39

41
Q

What is the limitation for an inoperative yaw damper coupled with failure of the Mach Trim Compensation system?

A

Limit altitude to 41,000 ft maximum

42
Q

What is maneauvering speed (Va)?

A

206 kcas

43
Q

What is the maximum speed with the mach trim inoperative?

A

MMO is reduced to 0.75 MT
