@ VY and climb NR 100%

27
Q

Engine failure in the hover with couple collection mode > 80% PI, actions?

A

Use collection force trim - use up to 160 PI
Set 10 degrees nose down in 1 sec
0 degrees pitch down in 1 sec + OEI 2.5 min PWR
NR 90% min
@ Vtoss and PROC, 5 degrees to maintain Vtoss - recover NR 102%
@ 200’ Vy - gear up
@ VY and climb NR 100%

28
Q

For an engine fire, why is it important to check the ECL?

A

The ECL has 2 independent indications:
1. Through the MAU
2. Directly to the ECL engine fire light

In a fire emergency if no ECL fire light illuminates and there are no signs of fire perform a fire detector test.
If during the test the ECL illuminates and there are no signs of fire, assume that the test circuit in the MAU is broken and land as soon as practical.

29
Q

If you see a 1 (2) FIRE DET CAS message during a fire warning what does this indicate?

A

Fire detector system failure.

30
Q

Can you lower the landing gear with a 1-2 DC GEN emergency with a loss of DC power?

A

No, it required DC electrical power (ESS BUS 1)

31
Q

During a 1-2 DC GEN emergency, if conducting an RNP approach, what should you consider?

A

The pilot MCDU is powered by MAIN BUS 1, If you elect to turn the BATTERY MAIN OFF for extended BATT power you can’t fly the RNP as you will lose the MCDU.
Co-pilot MCDU is powered bu the non-ess bus.

32
Q

During a 1-2 DC GEN emergency, if you moved no BATT switches, what is the expected battery life?

A

17 min

33
Q

During a 1-2 DC GEN emergency, if you turned the MAIN BATT OFF, what is the expected battery life?

A

?

34
Q

During a 1-2 DC GEN emergency, if you followed the extended flight endurance ECL, what is the expected battery life?

A

76 min

35
Q

During movement on an engine mode switch to off in flight due to an emergency, what should you do before selecting off?

A

Idle first in case you have selected the wrong engine.

36
Q

When pressing the ENG FIRE 1 (2) push button, what does this do?

A
  1. Arms the eng cartridges on both engines
  2. Closes the shut-off valve for that engine
  3. Closes the bleed valve for that engine
37
Q

What is the land/ditch immediately definition:

A

Continued flights are likely to be more hazardous than ditching, and landing in trees. The procedure for ‘emergency landing’ should be followed.

38
Q

What is the land as soon as practical definition:

A

Land at the nearest airfield where tech support can be achieved. If this is not practical, land at a safe landing site chosen for subsequent convenience. The duration of the flight and landing site are at the discretion of the pilot. Extended flight is not recommended.

39
Q

What is the establish safe flight conditions meaning?

A

Establish a safe track and altitude, while continuing with the emergency procedure to reduce the time necessary for conduct of a possible emergency landing.

40
Q

What is the safe OEI flight conditions definition?

A
  • suitable airspeed not less than Vtoss
  • The ability to obtain a positive ROC at acceptable pwr levels
  • Altitude with sufficient clearance from ground and obstacles
41
Q

List all 3 emergency transponder codes.

A

Emergency: 7700
Comms fail: 7600
Unlawful interference: 7500

Immediate actions for engine drive shaft failure?

A

Immediate actions for engine failure?

A
45
Q

A
46
Q

Immediate actions for rotor overspeed?

A

Q

Immediate actions for tail rotor drive failure in the hover?

A
48
Q

Immediate actions for tail rotor drive failure in flight?

A
49
Q

Immediate actions for tail rotor control failure in the low hover?

A
50
Q

Immediate actions for tail rotor binding in the hover?

A
51
Q

If the MGB OIL PRESS CAS warning illuminates (below 3.1), but the pressure is above 1.2 bar, what does this mean?

A

The most likely cause is the failure of 1 of the 2 MGB pumps.

52
Q

If on the HDY synoptic screen, a filter is shown block (orange cross) in bypass, what are your actions?

A

If discovered after a start, dispatch and continued flight are allowed to the flight or series of flights. Maintenance shall be carried out on shutdown on a maintenance base but within 10 hours.

53
Q

In the event of an emergency or abnormal situation, what basic procedures shall be followed?

A

MAINTAIN AIRCRAFT CONTROL - recognizes failure and establishes stable safe flight or immediate landing as appropriate.

ANALYSE THE SITUATION - identity warnings, cancel audio, warning lights, alarm or master caution and if appropriate, start diagnosing the problem

TAKE APPROPRIATE ACTION - Carry our immediate actions. Follow up with ECL. Carry out NCL.

54
Q

During a high-side emergency, what NR should you set for landing?

A

100%

55
Q

What is the definition of the mayday distress call?

A

Applicable when a grave and imminent danger threatens, and immediate assistance is required.

56
Q

What is the definition of the urgency pan call?

A

Applicable during conditions concerning the safety of the aircraft or persons, where immediate assistance is not required.

57
Q

What is the definition of land as soon as possible?

A

Land at the nearest safe place. Depending on the malfunction and where it occurs, this may require flight to a runway or to the nearest landfall or helideck. The flight should be at an altitude and airspeed that will allow for an immediate landing or ditching if the abnormal condition deteriorates.
