Offset 15 degrees yaw left
Reduce airspeed and height to position pad into the centre of the chin window at 250 ‘ with 15 - 20 GS
Maintain profile. using 400 - 500 PDM ROD passing through LDP
Max speed for touchdown of 5 GS

LDP above 250’:
Continue to pass through 100’ above LDP (initial point) with 30 GS and ROD between 400 - 500 PFM
Offset 15 degrees yaw left
Reduce airspeed and height to position pad into the centre of the chin window at 250 ‘ with 15 - 20 GS
Maintain profile. using 400 - 500 PDM ROD passing through LDP
Max speed for touchdown of 5 GS

  3. Parking brake
  4. Floats
  5. Compasses
  6. External lights
25

26
Q

When can’t you enter an offset in the MCDU?

A
  • 10nm from origin and 25nm from destination
  • pattern
27
Q

When can go-around be selected?

A

> 41kts

28
Q

When go-around is selected, what are parameters are captured?

A

1,000 ft/min climb, roll for wings-level and pitch for an airspeed of 80 KIAS or the current airspeed, whichever is higher. If below 70 kts it will engage a reference speed of 70 kts.
LNAV will capture.

29
Q

When coupled with ILS APP or VGP, will the auto-level function work and what indication do you get on your PDF?

A

Yes, there will be an automatic flair at 50 RADALT initiated at 150’, which will maintain that height.

GS or VGP will change to ALVL.

ALVL will not engage if the MAP is above 150 feet.

30
Q

When engaged to VGP, when will auto-level not engage and what indication do you see?

A

If the MAP is higher than 150’ AGL VTA (vertical track alert) will appear in the ADI and VGP will disengage at the MAP.

31
Q

When DCL is used for an ILS coupled, what are the parameters captured when DCL is engaged?

A

Approx 80 kts at a height not below 200/ AGL.

32
Q

When GA is captured, can you adjust the reference airspeed and vertical speed?

A

Yes, using the collective and cyclic trim switch.

33
Q

On the TAWS terrain display on the MFD, what is the purpose of the numerical values shown?

A

The data shows two elevation numbers that indicate the highest and lowest terrain currently being displayed, for example 150/85. The elevation numbers indicate terrain in hundreds of feet above MSL and are displayed with the highest terrain number first, and the lowest terrain number next.

34
Q

When TAWS mute is selected, how long is mute active and what mode is not inhibited?

A

5 min
MODE 6 - advisory alerts - BANK ANGLE, TAIL TOO LOW and auto call outs are still active.

35
Q

When is the look ahead envelope of the EGPWS reduced and inhibited?

A

Reduced: below 100 kts
Inhibited: below 70 kts

36
Q

EPGWS detects terrain or obstacle threats within what time ahead of the helicopter?

A

30 sec, caution terrain terrain or caution obstacle obstacle - repeated every 7 sec
20 sec, warning terrain terrain or warning obstacle obstacle - continues until clear of treat

37
Q

When SAR TAWS is selected, what modes are disabled?

A
  1. MODE 1 Excessive ROD SINK RATE
  2. MODE 4 Unsafe terrain clearance TOO LOW TERRAIN
  3. MODE 2 Excessive terrain closure rate terrain terrain
38
Q

Explain the PI limiting?

A

During collective coupled operation the collective movement is limited by the
following Power Index (PI) values:
* Maximum 97% AEO (reduced to 95% at altitudes above 10000 ft Hp)
* Maximum 106% AEO for airspeed less than 60 KIAS (5 MIN message
displayed beside collective cue)
* Maximum 140% OEI
* Minimum 5% AEO
* Minimum 10% OEI
When PI limiting function is active and is limiting maximum collective
movement, an amber LIM caption is displayed beside the collective cue.
If PI limiting is active with IAS engaged and the required reference for VS,
ALTA, RHT, GA, or ALT cannot be achieved then the airspeed will
automatically reduce as necessary to achieve the collective mode reference.
If the collective mode reference cannot be maintained when the airspeed
has reduced to a minimum of 80 KIAS, this airspeed will be maintained (IAS
caption is displayed in green) and the collective mode reference will be
reduced (the collective mode caption is displayed in amber).
CAUTION
IF PI LIMITING IS ACTIVE WITH ALT OR RHT ENGAGED AND
THE REFERENCE BAROMETRIC ALTITUDE OR RADIO HEIGHT
CANNOT BE MAINTAINED, THE AURAL WARNING “ALTITUDE –
ALTITUDE” WILL WARN THE PILOT WHEN THE MAXIMUM
ALLOWED DEVIATION FROM THE REFERENCE SETTING HAS
BEEN EXCEEDED

39
Q

When does the CVR record?

A

The CVR starts recording upon power application to the FDR/CVR Unit from ESS 1 bus and stops within 10 minutes if the FDR non-recording condition persists.
In a standard flight, the CVR starts recording as soon as the BATTERY MASTER switch is moved to ON and stops recording 10 minutes after the second engine is off after landing (Weight on Wheels).

40
Q

When the RAD MSTR switch is set to GND what radios and navs are available?

A

VHF NAV 1
VHF COM 2
ADF
DME

41
Q

What is the main wheel tyre pressure?

A

6800: 230 psi
7000 kit: 203 psi
