A
17
Q

Explain the PC1 clear area landing procedure

A

@ 200’ ROD <500 PFM
Initiate decel to achieve LDP (50 feet, 50 kts airspeed, less than 350 FPM ROD)
Nose shall be reduced below 15 degrees by 15’

18
Q

What is the LDP for PC1 clear area?

A

50 feet, 50 kts airspeed, less than 350 FPM ROD

19
Q

What is the LDP for PC1 short field?

A

50 feet, 20 GS

20
Q

Explain the PC1 short field landing procedure

A

@ 200’ ROD <500 PFM
Initiate decel to achieve LDP (50 feet, 20 GS, less than 350 FPM ROD)
Nose shall be reduced below 15 degrees by 15’

21
Q

Can an onshore helipad and short-field LDP be increased?

A

Yes, a variable LDP can be used, 50 - 400’ at 20 GS (but no less than 20 kts) with a ROD < 350 FPM

22
Q

When using the variable short-field and onshore helipad variable LDP, what is the landing profile?

A

@ 150’ above the LDPv ROD < 500 PFM
Initiate decel to achieve LDP height at 20 GS with a ROD < 350 FPM
Nose shall be reduced below 15 degrees by 15’

23
Q

What is the LDP for a PC1 confined area?

A

100 - 400’

24
Q

Explain the PC1 confined area landing profile?

A

LDP below 250’:
Continue to pass through 350’ (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

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

25
Q

What are the AW139 after take-off checks by memory?

A
  1. RPM selector
  2. Landing gear
  3. Parking brake
  4. Floats
  5. Compasses
  6. External lights
26
Q

What are the AW139 final by memory?

A
  1. RPM selector
  2. Landing gear ‘three greens’
  3. MDF
  4. Radar
  5. Landing site
  6. Cabin
27
Q

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

A
  • 10nm from origin and 25nm from destination
  • pattern
28
Q

When can go-around be selected?

A

> 41kts

29
Q

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

A

1000 FPM ROC & 80 kts. IF below 70 kts it will engage a reference speed of 70 kts.
LNAV will capture.

30
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.

31
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.
VGP will change to VTA (vertical track alert)

32
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.

33
Q

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

A

Yes, using the collective and cyclic trim switch.

34
Q

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

A

The highest and lowest displayed terrain elevation

35
Q

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

A

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

36
Q

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

A

Reduced: below 100 kts
Inhibited: below 70 kts

37
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

38
Q

When SAR TAWS is selected, what modes are disabled?

A
  1. MODE 1 SINK RATE ‘terrain terrain’
  2. MODE 4 TOO LOW TERRAIN
