Performance-Based Navigation

Question 1

What are the different navaids used in PBN?

Answer 1

What are the three different types of GNSS augmentations?

Answer 2

• Aircraft based (ABAS)
• Space-based (SBAS)
• Ground-based (GBAS)

Question 3

What is the function of Aircraft Autonomous Integrity Monitoring (AAIM) and Receiver Autonomous Integrity Monitoring (RAIM)?

Answer 3

• Compares GNSS position with other sensors e.g. IRS

Question 4

What is the difference between RNAV and RNP specifications?

Answer 4

C.) RNP specifications have a requirement for on-board performance monitoring and alerting.

Question 5

In the PBN specifications, the number included in the specification name refers to:

Answer 5

C.) The required accuracy, in Nm, of the navigation system.

Question 6

Which of the following is NOT a basic function required in all PBN Navigation Specifications?

Answer 6

B.) Facility to operate offset parallel tracks.

Question 7

Which of the following statements regarding the errors in the PBN model is true?

Answer 7

A.) Path Definition Error is usually negligible

Question 8

A requirement of PBN is that the total system error :

Answer 8

C.) Is equal or less than the required accuracy of the navigation specification for at least 95% of the time.

Question 9

The navigation database:

Answer 9

B.) Is valid for 28 days and must be confirmed valid prior to operating.

Question 10

What is PBN comprised of in terms of RNAV?

Answer 10

RNAV (GNSS)
RNAV 1 (RNAV SID)
RNAV 2 ( TERMINAL)
RNAV 5 (TERMINAL)
RNP 4 (OCEANIC)
RNP 1 (STAR)

Question 11

When considering a notified RAIM outage that affects a planned flight, which of the following is correct?

Answer 11

C.) A RAIM outage of more than 5 minutes will require a re-routing or re-timing of the flight.

Question 12

When planning for an RNP APCH arrival at destination, it is necessary to ensure:

Answer 12

C.) Sufficient means are available to permit landing at either the destination or alternate in the event of a loss of the RNP capability.

Question 13

In order to operate on PBN routes and procedures:

Answer 13

C.) The aircraft must be certified to the required navigation specification and the pilot must be approved for PBN operations.

Question 14

When operating in PBN airspace, if a system failure results in a loss of PBN capability:

Answer 14

A.) ATC must be notified using the phrase “unable RNP due…”

Question 15

The Radius to Fix Leg is usable ___?

Answer 15

C.) Is usable in terminal airspace by aircraft certified specifically to perform RF Legs

Question 16

Why must a SID or STAR be selected by name from the database rather than created manually by insertion of the waypoints?

Answer 16

B.) The database coding of the procedure includes additional information such as the RNP value for alerting

Question 17

What modifications are allowed to a SID or STAR once it has been selected from the database?

Answer 17

A.) Direct to.. Actions may be performed, at the request of ATC

Question 18

Approach operations are classified as either 2D or 3D. a 3D approach operation:

Answer 18

B.) Is performed to a DA, allowing for height loss after the commencement of a missed approach.

Question 19

Which statement is correct regarding approach operations to LNAV/VNAV?

Answer 19

B.) Either Baro-VNAV or SBAS may be used to operate these approaches.

Question 20

Missed approaches based on PBN navigation specifications:

Answer 20

A.) May be used, provided the reason for the missed approach was not the loss of PBN capability on the aircraft.

Question 21

Verification of the approach procedure prior to operation:

Answer 21

B.) Should be performed by comparison with the appropriate chart.

Question 22

For RNP APCH approaches using Baro-VNAV, the temperature published on the chart

Answer 22

B.) Is the minimum temperature at which use of the procedure is authorized.

Question 23

Vertical deviation is displayed to the pilot using a deviation scale. These scales:

Answer 23

A.) Will be calibrated such that full scale deflection represents the maximum allowed deviation from the vertical path.

Question 24

Which navigation aids may be used in PBN?

Answer 24

B.) GNSS, VOR, DME and INS

Question 25

When completing a flight plan for a flight which is intended to include operations in PBN airspace:

Answer 25

Block 18 contains information on the aircraft PBN capabilities relevant to the flight, and is limited to 8 entries
