The Performance-based Navigation (PBN) concept specifies that aircraft RNAV and
RNP system performance requirements be defined in terms of:
Accuracy, integrity, continuity, and functionality.
Under PBN, generic navigation requirements are defined based on:
Operational requirements.
What advantage(s) does Performance-based Navigation provide?
It reduces the need to maintain sensor-specific routes and procedures.
What is the main difference between RNAV and RNP?
RNP includes the requirement for onboard performance monitoring and alerting.
Both RNP and RNAV specifications have certain functional requirements, including
which of the following?
Navigation data storage function.
Does the PBN concept include vertical performance?
No, although some navigation specifications include requirements for vertical guidance
using GNSS or barometric vertical navigation.
For oceanic, remote, en-route, and terminal operations, an RNP specification is
designated as:
RNP/RNAV "X"; such as RNP 4.
True or False? An aircraft approved for RNP 1 is automatically approved for RNP 4.
False. Aircraft approved for more stringent requirements may not meet functional
requirements of less stringent specifications.
In order to be eligible for RNP or RNAV operations, an aircraft must:
Have a statement of compliance in the AFM, POH, or operating manual for their
avionics.
RNAV is a method of navigation which permits aircraft operation on any desired flight
path within the coverage of station referenced navigation aids, self-contained aids, or a
combination. To use RNAV, the specified RNAV accuracy must be met for how much of
the flight time?
95%.
When conducting an RNAV DP or STAR procedure, differences between the chart and
navigation display are operationally acceptable as long as they do not exceed:
3 degrees.
In the event that any loss of RNAV capability is experienced the pilot should:
Notify ATC including the proposed course of action.
During a STAR, a "descend via" clearance provides pilots the option to:
Descend from a previously assigned altitude to the waypoint altitude at the pilot's
discretion.
If ATC issues a heading assignment that takes the aircraft off a procedure, do the
specified route-accuracy requirements still apply?
No. While off the published procedure, the accuracy requirements do not apply.
Prior to commencing any kind of RNP procedure, flightcrews should:
