Performance-based Navigation (PBN)
ACTUAL QUESTIONS AND CORRECT
ANSWERS
1 . The Performance-based Navigation (PBN) concept specifies that aircraft RNAV and RNP
system performance requirements be defined in terms of: - CORRECT
ANSWERS✅✅Preciseness, accuracy, sustainability, and universality.
Functionality, simplicity, universality, and cost.
** Accuracy, integrity, continuity, and functionality.
Periodically, cost, simplicity, and learning curve.
2 . Under PBN, generic navigation requirements are defined based on: - CORRECT
ANSWERS✅✅** Operational requirements.
Individual aircraft capabilities.
Practical weather and terrain minimums.
Individual ground control capabilities.
3 . What advantage(s) does Performance-based Navigation provide? - CORRECT
ANSWERS✅✅** It reduces the need to maintain sensor-specific routes and procedures.
Increases cost involved with sensor-specific routes.
It makes airspace routes more complex.
Broadens the scope of possible navigation specifications worldwide.
4 . What is the main difference between RNAV and RNP? - CORRECT
ANSWERS✅✅RNAV is only used enroute and during missed approach procedures.
** RNP includes the requirement for onboard performance monitoring and alerting.
RNAV includes the requirement for onboard performance monitoring and alerting.
RNP does not have terminal, approach, or departure applications.
5 . Both RNP and RNAV specifications have certain functional requirements, including
which of the following? - CORRECT ANSWERS✅✅Automatic communication of basic
navigation information to ground control.
, 3D display of aircraft position to include altitude, airspeed, and bearing.
Display of other aircraft in the area with speed and altitude.
** Navigation data storage function.
6 . Does the PBN concept include vertical performance? - CORRECT ANSWERS✅✅Yes,
however, vertical performance is only specified for terminal and approach operations.
** No, although some navigation specifications include requirements for vertical guidance
using GNSS or barometric vertical navigation.
Yes, vertical performance is a standard part of the PBN concept and is utilized to reduce
vertical separation between aircraft.
No, vertical performance requirements are not a part of PBN, though some instrument
approaches using RNAV or RNP may require vertical guidance.
7 . For oceanic, remote, en-route, and terminal operations, an RNP specification is designated
as: - CORRECT ANSWERS✅✅TSE "X"; such as TSE 4.
"X" TSE; such as 4 TSE.
** RNP/RNAV "X"; such as RNP 4.
"X" RNP/RNAV; such as 4 RNAV.
8 . True or False? An aircraft approved for RNP 1 is automatically approved for RNP 4 -
CORRECT ANSWERS✅✅** False. Aircraft approved for more stringent requirements may
not meet functional requirements of less stringent specifications.
True. Aircraft approved for more stringent requirements automatically meet requirements for
all less stringent specifications.
False. Unless the aircraft is approved for both RNAV and RNP, in which case it is approved
for all specifications.
True. But it is common practice to obtain both approvals anyway in case there are additional
requirements that must be met.
9 . In order to be eligible for RNP or RNAV operations, an aircraft must: - CORRECT
ANSWERS✅✅Be examined by an authorized representative of the state conducting RNP or
RNAV operations.
Undergo compliance testing through a State authorized maintenance facility.
** Have a statement of compliance in the AFM, POH, or operating manual for their avionics.
