16 PBN Approaches and Practices

Question 1

RNAV10 and RNP10

Answer 1

RNAV and RNP, both come under PBN.
Same spec,

Question 2

RNAV10 (RNP10)

Answer 2

Oceanic / Remote Areas
At least 2 indepdent / servicable LRNS
INS/IRS / FMS or a GNSS
If duel INS/IRS, aircraft have a limited time they can operate for.

Question 3

RNAV 5 (B-RNAV)

Answer 3

Continental en-route
Manual data entry is acceptable

Question 4

RNAV 2

Answer 4

Enroute continental, arrivcal and departure.

Question 5

RNAV 1

Answer 5

Arrival / Departure phases.

Specific waypoint from the database can be inserted, however manual data entry of points is not permitted.

Approach, but not final.

Question 6

Requirements when using RNAV 1/2 SID and STAR?

Answer 6

Must be retrieved by name.

Question 7

RNP APCH

Answer 7

Must be retrieveable from onboard nav database by procedure name. All require RAIM.

Question 8

RNP APCH

LNAV

Answer 8

2D guidance along the approach track. A non-precision approach ending at MDA/H.

Question 9

RNP APCH

LNAV/VNAV

Answer 9

3D guidance along the approach track, traditionally using barometric altitude to determine the aircraft’s height and thus provide vertical guidance in the final approach segemnt. A non-precision approach ending at a derived DA/H

Angular approach.

Question 10

RNP APCH

LP

Answer 10

Localiser performance

2D guidance using SBAS. A non-precision approach ending at a derived MDA/H.

Question 11

RNP APCH

LPV

Answer 11

Localiser Performance with vertical guidence.

3D guidance using SBAS to determine geometrically, the aircraft’s height (geometric altitude) and thus provide vertical guidance. A precision approach ending at DA/H.

Requires the FAS datablock

Angular Aproach

Question 12

RNP AR APCH

Answer 12

Authorisation is required. Involves more training.

Question 13

A-RNP?

Answer 13

Advanced A-RNP, incorporates RNAV 5, RNAV/ RNP 2, RNAV/RNP 1 and RNP APCH.

Question 14

FAS Datablock?

Answer 14

Describes final approach path, the obsticles and things that can effect radio signals.

Question 15

Offset flight path?

Answer 15

Parrallel offset enables the AC to fly a path paralelel to, but offset left or right from the original active route.

By 1 or 2 miles

Offset interceptions must be <45 degrees.

Question 16

Effect of tempertaure on bara-alt usage?

Answer 16

Temperature effects also influence terrain clearance on final approach segment. Altimeters are calibrated in accordance with the international standard atmosphere (ISA). In case of low temperature, the pressure layers in the atmosphere move closer together resulting in a lower true altitude than indicated. This means that the approach path flown by an aircraft would be shallower than expected, with a lower glide path angle.
