…………………………………………
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.

Question 42

Which of the following statements is true regarding an offset flight path?

Answer 42

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.

Question 43

Regarding Performance Based Navigation (PBN). Which of the following named leg types refers to a fixed radius path for en-route sections.

........................................
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
