RNP AR 3

Question 1

What is the PM call for vertical deviation on RNP AR approach?

Answer 1

V/DEV

Question 2

When should the PM call V/DEV?

Answer 2

Half dot on PFD scale

Question 3

How much does half a dot represent on vertical PFD scale on RNP AR approach?

Answer 3

50ft

Question 4

What contributes to the total vertical system error in RNP AR approaches?

Answer 4

Total vertical system error = Path defintion error + V/DEV + altimetry system error. No provision is made for altimeter setting errors

Question 5

What is the vertical error budget?

Answer 5

Provision to contain the vertical deviation due to vertical errors on an RNP AR approach. This vertical error budget remains above the obstacle clearance surface along the final approach path. This only applies to the final approach.

Question 6

What is the maximum permitted vertical deviation during final approach on RNP AR approach?

Answer 6

3/4 dot on the V/DEV scale. (75ft). This cannot be exceeded

Question 7

What are the operational limits vertically and laterally on an RNP AR approach?

Answer 7

Laterally, 1xRNP

Vertically, 75ft

Question 8

What are the obstacle limits vertically and laterally on an RNP AR approach?

Answer 8

Laterally 2xRNP

Vertically is vertical error budget

Question 9

If temperature is colder than ISA, is the aircraft higher or lower than expected?

Answer 9

Lower. FMS assumes ISA temperature and makes no compensation

Question 10

On an RNP AR approach, what must you do when heading ‘direct to’ a waypoint which is the beginning of a radius to fix leg?

Answer 10

Use ‘radial in’ function to avoid overshooting after the waypoint

Question 11

What are the main cautions when using direct to on an RNP AR approach?

Answer 11

Can only be done above MSA until established on F-PLN leg, and must use radial in function if direct to a waypoint preceeding a radius to fix (arc) leg

Question 12

What is the maximum angle of bank with AP engaged? Why is this a consideration on RNP AR approaches?

Answer 12

30 degrees. Strong winds may impact required turn radii

Question 13

When is autopilot use compulsary in RNP AR operations?

Answer 13

When RNP < 0.3

Question 14

Down to what RNP can we use the Augur RAIM prediction on the company iPad?

Answer 14

RNP 0.3

Question 15

Can you do an RNP AR approach in all weather conditions?

Answer 15

No, not in thunderstorms as deviation may not be possible to avoid weather due to terrain. Also careful consideration needs to be given to the wind effect on RF legs

Question 16

How do you deselect a navaid?

Answer 16

Data - Position monitor - Sel Navaids - deselect

Question 17

What is the decision to deselect navaids prior to an RNP AR procedure based on?

Answer 17

NOTAM and CCI guidance

Question 18

When can you not use FMS predictive GPS page for RNP operations?

Answer 18

When RNP < 0.3, or when operating around mountainous terrain due to the mask angle

Question 19

When preparing for an RNP approach, and checking the estimated nav accuracy, what else do you need to consider?

Answer 19

That the EPE is less than required FOR THE PROCEDURE, not currently required

Question 20

For RNP AR departures <0.3 when must the autopilot be engaged?

Answer 20

ASAP after 100ftRA

Question 21

For RNP AR departures what must you check when lined up on the runway?

Answer 21

That the L/DEV is centred

Question 22

When will altitude be shown in magenta on the PFD?

Answer 22

When a level segment is expected at that altitude

Question 23

When should you use LNAV minima? When should you use VNAV minima?

Answer 23

VNAV if temperature within limits. No temperature compensation required. LNAV if temperature is below limits, and temperature compensation needs to be applied

Question 24

What are the ‘blue arrow’ FINAL APP engagement conditions? What if these are not met?

Answer 24

X-track less than 1.5mn
Below ALT CSTR + 250ft
MCDU predictions exist
APP phase activated

If not met, arrow will be white

Question 25

How would you fly an RNAV Visual approach? What minima would you set?

Answer 25

AP can be used down to 250ft AGL. No minima set. The chart minima represents the weather required to commence the approach

Question 26

How do you know if we have authorisation for a specific RNP AR approach?

Answer 26

It will be noted in the CCI

Question 27

On an RNAV (GNSS) approach, what is the PM callout for excessive lateral deviation? When should it be said?

Answer 27

CROSS TRACK, when deviation > 0.1nm

Question 28

On an RNAV (GNSS) approach, what is the maximum permitted lateral deviation?

Answer 28

0.3nm
