Q

Picture of STAB, condition, show me different modes - auto and manual. VNE arc too. What’s it all mean?

A

White mean auto, yellow mean manual, number is degree of tilt. VNE arc appears based off position of STAB failure to corresponding airspeed.

21
Q

STAB degraded advisory means that the STAB is what?

A

Limited mode indicates the stabilization has reverted to reduced functionality.

22
Q

2 FCCs are identical and interchangeable, however TRIM is controlled by which one?

A

2 FCC

23
Q

Turn coordination is a feature of FPS and is available at or above BLANK IAS in the BLANK axis?

A

At or above 50 IAS in the YAW axis

24
Q

During the power up IBIT chip detectors should not appear however if multiple chip detectors fail a BLANK caution will appear.

A

CHIP IBIT FAIL

25
Q

Which of the following is a characteristic of the 60M rotor system?

A

Fully articulating, wide chord blades, rotor brake

26
Q

Main XMSN pressure caution, main XMSN OIL HOT, loss of cooling oil supply will lead to electrical or mechanical failure of what?

A

Main generators

27
Q

ENG POWER CONT levers are blocked from advancing past the idle position when BLANK is engaged.

A

Rotor brake

28
Q

Purpose of main rotor blade dampers?

A

Limit hunting (lead and lag movements)

29
Q

Primary source of power for 60M is provided by?

A

Main generators - rated at 30/45 KVA, cooled by XMSN oil, and provides 115/200 VAC, 3 phase, 400 Hz power.

30
Q

Batteries will provide uninterrupted DC power for approx how long?

A

15 minutes or 12 minutes with external lighting CHANGE **

31
Q

Picture of MFDs - all MFDs have turned off except #3 pilot inboard, with indications below - what is the emergency?

A

Main generators failed / DUAL GEN FAIL CHANGE **

32
Q

Dual converter fail - which buses are lost?

A

No. 1 and No. 2 DC primary buses

33
Q

If a converter failure occurs what should we not do?

A

Do not turn off the battery switch corresponding to the failed converter. This will cause the battery bus tie connector to close resulting in loss of the associated battery bus and DC essential bus.

34
Q

BATT status indicator - BATT GOOD/BATT LOW - where is that located?

A

Cold Capsule Lights

35
Q

What is the order of priority of power?

A

First priority - main generators, second priority - APU generator, third priority external power receptacle

36
Q

Prior to turning on APU generator what should the pilot do?

A

Clear stabilator

37
Q

Show caution/advisory - TR SERVO 1 FAIL - first action step?

A

TAIL SERVO switch - BACK UP

38
Q

MFD indication - condition - #1 hyd pump fail , pri servo fail, TR servo 1 fail, what is first step? First step for pilot not on the controls when at a comfortable airspeed.

A

BACKUP HYD PUMP - ON CHANGE**

39
Q

Use of cyclic mounted stab slew up switch - what does it do for us, when should we use it?

A

provides the ability to manually slew the stabilator up. Emergencies. Arrest nose down pitch attitude. CHANGE **

40
Q
  • SAS off caution would appear if both SAS 1 and SAS 2 have been turned off OR?
A

Loss of actuator pressure

41
Q

If the intermediate XMSN oil hot caution appears what do we do? Or TR XMSN oil hot? EP?

A

Land as soon as possible

42
Q

Loss of TR thrust during cruise flight - we should autorotate and maintain airspeed at what airspeed?

A

At or above 80 knots

43
Q

The fuzz burn feature of the is deactivated when? If fuzz burn is activated what happens?

A

The fuzz burn-off feature is deactivated when oil temperature reaches 140°C.

44
Q

If we lose #1 and #2 tail servo, limited TR control is still available because of the limited yaw range - roll on at what airspeed or above?

A

Because of the limited yaw control range available, a roll-on landing at 40 KIAS or above is required.

45
Q

Operating at idle with gust lock engaged on a rotor brake equipped 60M is what?

A

Prohibited

46
Q

How are main generators different from APU Gen? How are they cooled?

A

Liquid cooled from main mod oil, no power restriction. APU gen is air cooled.

47
Q

What is the primary source of DC power?

A

Primary DC power is obtained from two converters (transformer-rectifiers)

48
Q

If a leak occurs in the pilot assist servo, example - collective boost, which indications shown below would NOT occur?

A

What WOULD appear - RES 2 LOW, FPS FAIL, TRIM FAIL, BOOST SERVO OFF, and SAS OFF. Who knows what wrong answer they’ll throw out. CHANGE **

49
Q

Loss of both No. 2 HYD PUMP and BACKUP PUMP would result in a loss of what?

A

PAM, #2 PRI SERVO CHANGE**
