An error in PBN operations relating to the execution of a flight along a defined path is a:
Flight Technical Error (FTE)
…………………………
FTE relates to the aircrew or autopilot’s ability to follow the defined path or track, including any display error (e.g. course deviation indicator (CDI) centring error).
When preparing to commence an RNP AR APCH procedure the flight crew check the routing including the waypoint sequence and notice that one waypoint is missing. Which is the correct action to take?
Continue using conventional navigation aids
An error during PBN operations rising from the RNAV system and its inability to accurately specify the desired path is a:
Path Definition Error (PDE)
…………………………………………..
PDE occurs when the path defined in the RNAV system does not correspond to the desired path, i.e. the path expected to be flown over the ground.
RNP 5 (Required Navigation Performance) requires a navigation accuracy of:
+/- 5 NM lateral 95% of the flight time.
The Total System Error (TSE) during a PBN operations encompasses:
Path Definition Errors, Flight Technical Errors, Navigation System Errors
From the selection below, choose a PBN procedure which is classified as a non-precision approach (NPA):
RNP approach to LNAV minima.
RNP 0.3 navigation specification is used:
in all phases of flight, except for oceanic, remote and final approach phases.
Can operators extend their RNAV 10 navigation capability time?
Yes, they can extend the time by updating.

in the en-route continental, arrival and departure phases of flight.
RNP AR APCH is used:
in the approach phase of flight.
PBN path terminator “DF” means:
Direct Fix
PBN path terminator “IF” means:
Initial Fix
An error during PBN operations in the accuracy of determining actual aircraft coordinates is a:
Navigation System Error (NSE)
In case a discrepancy occurred between the on-board navigation database and the published procedure:
pilots must not fly an RNP APCH.
What is correct about fly-by / fly-over waypoints and turns?
A fly-by waypoint is a waypoint which requires turn anticipation to allow for the tangential interception of the next route segment or procedure.
Which of the following PBN approaches is a non-precision instrument approach procedure designed for 2D approach operations?
RNP APCH to LNAV minima
What is true about performance based navigation (PBN)?
It is not sensor-specific.
Concerning an RNP AR APCH, what does AR stand for?
Authorisation required
List all basic functional requirements of the RNAV and RNP specifications:
1) continuous indication of lateral deviation
2) distance/bearing to active waypoint
3) GS or time to active waypoint
4) navigation data storage
5) failure indication
1), 2), 3), 4), 5)
List all components of performance based navigation (PBN):
navigational aid infrastructure, navigation specification and navigation application
The difference between Area Navigation (RNAV) and Required Navigation Performance (RNP). RNP is RNAV that includes requirements for:
on-board performance monitoring and alerting.
An error during PBN operations related to the execution of flight along the defined path refers to a:
Navigation System Error (NSE)
…………………………………………
NSE refers to the difference between the aircraft’s estimated position and actual position.
The PBN path terminators define:
a specific type of termination of the previous flight path.
……………………………………………..
A terminator defines the end of a PBN leg. When combined with a description of the path leading up to the terminator the PBN leg type is defined.
Which of the following statements is true about RNP / RNAV navigation specifications?
Aircraft approved to the more stringent accuracy requirements may not necessarily meet some of the functional requirements of the navigation specification that having a less stringent accuracy requirement.
RNAV 10 requires that aircraft operating in oceanic and remote areas be equipped with at least:
two independent and serviceable long-range navigation systems (LRNSs) comprising an INS, an inertial reference system (IRS)/flight management system IRS (FMS) or a GNSS.
In oceanic/remote, en-route, and terminal phases of flight, PBN is limited to:
operations with linear lateral performance requirements and time constraints.
…………………………………………
For oceanic/remote, en-route and terminal phases of flight, PBN is limited to operations with linear lateral performance requirements and time constraints due to legacy reasons associated with the previous RNP concept.
In the approach phases of flight, PBN accommodates both linear and angular laterally guided operations. The guidance to fly the ILS/MLS/GLS procedure is not provided by the RNP system, consequently, ILS/MLS/GLS precision approach and landing operations are not included in this Manual.
Concerning PBN - Performance Based Navigation - what is the name of a curved terminal or approach section, defined by fix, radius & arc length?
Fixed radius path.
PBN path terminator “CA” means:
Course to Altitude
RNP 2 is used:
in the en-route, oceanic and remote phases of flight.
In the approach phases of flight, PBN accommodates:
both linear and angular laterally guided operations.
……………………………………………………..
In the approach phases of flight, PBN accommodates both linear and angular laterally guided operations. The guidance to fly the ILS/MLS/GLS procedure is not provided by the RNP system, consequently, ILS/MLS/GLS precision approach and landing operations are not included in this Manual.
The factors used to define area navigation (RNAV) or required navigation performance (RNP) system performance requirements:
accuracy, integrity, continuity
Which of the following statements is true regarding an offset flight path?
It allows flight crew to specify a lateral offset from a defined route.
………………………………..
An Offset Flight Path allows flight crew to specify a lateral offset from a defined route.
Background Information
The B737-800 FMS CDU has the facility to select an OFFSET Flight Path from the MENU page.
Once the appropriate line select key (LSK) is pressed, the crew then select the entry and exit points for the offset flight path and the distance left or right of track that the offset flight path is to be flown at.
The computer will then calculate the appropriate headings to be flown to intercept the offset flight path and to regain the defined track on leaving the offset flight path.
The offset flight path shows up as a dashed magenta line parallel to the solid magenta line representing the defined track.
Regarding Performance Based Navigation (PBN). Which of the following named leg types refers to a fixed radius path for en-route sections.
FRT leg type. ........................................ A 'Fixed Radius Path' takes two forms: Radius to Fix (RF) This is used to fulfil a requirement for a specific curved path radius in a terminal or approach path procedure. Fixed Radius Transition (FRT) This is intended to be used in en-route procedures and have two possible radii: 22.5 nm for high altitude routes 15 nm for low altitude routes
