RNP

Question 1

RNP

Answer 1

Required Navigation Performance

Question 2

Required Navigation Performance (RNP) is

Answer 2

• a STATEMENT of navigation equipment and service performance
• it is Area Navigation (RNAV) WITH navigation monitoring AND alerting

Question 3

all RNAV approaches are what

Answer 3

all Area Navigation (RNAV) approaches ARE Required Navigation Performance (RNP) approaches

Question 4

most USA RNP approaches are titled what

Answer 4

RNAV GPS

Question 5

what about RNAV (RNP)

Answer 5

• they are only titled this in the USA
• they are approaches that are Authorization Required (AR)
• they require speaking FAA approval for the crew, aircraft, & operation

**in other countries RNP is in EVERY TITLE regardless of needing AR or not

Question 6

what are RNP approach minima and equipment (1st type)

Answer 6

GLS (GBAS Landing System) DA minima using GBAS

Question 7

what are RNP approach minima and equipment (2nd type)

Answer 7

LP (Localizer Performance RNAV/RNP approach) MDA
or

LPV (Localizer Precision with Vertical guidance approach) DA minima require RNP achieved by WAAS

Question 8

what are RNP approach minima and equipment (3rd type)

Answer 8

LNAV/VNAV (Lateral & Vertical Navigation) DA achieved by VNAV-approved WAAS or BARO-VNAV system

Question 9

what are RNP approach minima and equipment (4th type)

Answer 9

LNAV (Lateral Navigation) MDA achieved by a basic UNAUGMENTED ifr approved GPS

Question 10

what are RNP approach minima and equipment (all types)

Answer 10

• GLS (GBAS Landing System) DA minima using GBAS
• LP (Localizer Performance RNAV/RNP approach) MDA
  or

LPV (Localizer Precision with Vertical guidance approach) DA minima require RNP achieved by WAAS

• LNAV/VNAV (Lateral & Vertical Navigation) DA achieved by VNAV-approved WAAS or BARO-VNAV system
• LNAV (Lateral Navigation) MDA achieved by a basic UNAUGMENTED ifr approved GPS

Question 11

what are the accuracies of RNP

Answer 11

95% accuracy of flight time

enroute = 2NM
terminal & departure = 1NM
final approach = 0.3NM

*see picture for reference

Question 12

A-RNP

Answer 12

Advanced Required Navigation Performance (RNP)

a higher RNP standard mandatory for RNP AR, that require capability for:
- radius-to-fix (RF) legs
- scalable RNP
can gradually vary between 1.0 & 3.0 ( or as low as 0.1) RNP values
- parallel offset flight plan generation
