Performance-Based Navigation Flashcards
What are the different navaids used in PBN?
- VOR (limited due to angular error)
- DME-DME position fixes - accuracy of 0.2 nm
- GNSS
What are the three different types of GNSS augmentations?
- Aircraft based (ABAS)
- Space-based (SBAS)
- Ground-based (GBAS)
What is the function of Aircraft Autonomous Integrity Monitoring (AAIM) and Receiver Autonomous Integrity Monitoring (RAIM)?
- Compares GNSS position with other sensors e.g. IRS
What is the difference between RNAV and RNP specifications?
C.) RNP specifications have a requirement for on-board performance monitoring and alerting.
In the PBN specifications, the number included in the specification name refers to:
C.) The required accuracy, in Nm, of the navigation system.
Which of the following is NOT a basic function required in all PBN Navigation Specifications?
B.) Facility to operate offset parallel tracks.
Which of the following statements regarding the errors in the PBN model is true?
A.) Path Definition Error is usually negligible
A requirement of PBN is that the total system error :
C.) Is equal or less than the required accuracy of the navigation specification for at least 95% of the time.
The navigation database:
B.) Is valid for 28 days and must be confirmed valid prior to operating.
What is PBN comprised of in terms of RNAV?
RNAV (GNSS) RNAV 1 (RNAV SID) RNAV 2 ( TERMINAL) RNAV 5 (TERMINAL) RNP 4 (OCEANIC) RNP 1 (STAR)
When considering a notified RAIM outage that affects a planned flight, which of the following is correct?
C.) A RAIM outage of more than 5 minutes will require a re-routing or re-timing of the flight.
When planning for an RNP APCH arrival at destination, it is necessary to ensure:
C.) Sufficient means are available to permit landing at either the destination or alternate in the event of a loss of the RNP capability.
In order to operate on PBN routes and procedures:
C.) The aircraft must be certified to the required navigation specification and the pilot must be approved for PBN operations.
When operating in PBN airspace, if a system failure results in a loss of PBN capability:
A.) ATC must be notified using the phrase “unable RNP due…”
The Radius to Fix Leg is usable ___?
C.) Is usable in terminal airspace by aircraft certified specifically to perform RF Legs
Why must a SID or STAR be selected by name from the database rather than created manually by insertion of the waypoints?
B.) The database coding of the procedure includes additional information such as the RNP value for alerting
What modifications are allowed to a SID or STAR once it has been selected from the database?
A.) Direct to.. Actions may be performed, at the request of ATC
Approach operations are classified as either 2D or 3D. a 3D approach operation:
B.) Is performed to a DA, allowing for height loss after the commencement of a missed approach.
Which statement is correct regarding approach operations to LNAV/VNAV?
B.) Either Baro-VNAV or SBAS may be used to operate these approaches.
Missed approaches based on PBN navigation specifications:
A.) May be used, provided the reason for the missed approach was not the loss of PBN capability on the aircraft.
Verification of the approach procedure prior to operation:
B.) Should be performed by comparison with the appropriate chart.
For RNP APCH approaches using Baro-VNAV, the temperature published on the chart
B.) Is the minimum temperature at which use of the procedure is authorized.
Vertical deviation is displayed to the pilot using a deviation scale. These scales:
A.) Will be calibrated such that full scale deflection represents the maximum allowed deviation from the vertical path.
Which navigation aids may be used in PBN?
B.) GNSS, VOR, DME and INS
When completing a flight plan for a flight which is intended to include operations in PBN airspace:
Block 18 contains information on the aircraft PBN capabilities relevant to the flight, and is limited to 8 entries
