Ch. 16: PBN Approaches And PBN Practices

Question 1

What do offset flight paths permit crew to do?

Answer 1

Fly parallel to defined route, by a fixed distance.

Question 2

What must RNP APCH procedures be retrievable by, and what must they conform to?

Answer 2

By name, from nav database; published chart

Question 3

RNP APCH - LNAV?

Answer 3

2D non-precision instrument approach procedure (IAP)

Question 4

RNP APCH - LNAV/VNAV? Where’s the lateral guidance from? Vertical? What is critical in terms of barometric data?

Answer 4

3D non-precision approach IAP

Lateral guidance - GNSS

Vertical guidance - barometric or SBAS (must be certified for IAP)

Barometric - correct altimeter setting critical, and temperature must be within limits (or automatically compensated)

Question 5

RNP APCH - LPV? Which 2 things does it require?

Answer 5

3D precision IAP

• FAS data block, describing final approach path.
• SBAS.

Question 6

What does RNP AR APCH require?

Answer 6

Special authorisation

Question 7

Which 4 things does advanced RNP (A-RNP) incorporate?

Answer 7

RNAV 5, RNAV/RNP 2, RNAV/RNP 1, and RNP APCH
