ERASE displays when a route modification is pending. INDEX displays when no
route modification pending.
ERASE -
Push – removes route modifications not executed and displays the original route.
INDEX -
Push – displays DEP/ARR INDEX page.
4 RUNWAYS
Displays a list of runways for the selected airport.
A runway selected on theRTE 1/X page displays as <SEL> or <ACT>.
Push -
• selects runway for use in the route. All other runways no longer display
• SIDs associated with selected runway remain, all others no longer display
• subsequent change of a runway deletes departure procedures previously
selected
5 <SEL>, <ACT>
Selecting an option displays <SEL> inboard of the option and creates a route
modification. After executing the modification, <SEL> becomes <ACT>.
Executing a modification or leaving the page and returning displays all options
and <SEL> or <ACT> prompts.

Navigation Radio Page
VOR and ILS navigation radios are normally autotuned by the FMC. ADF radios
are manually tuned. NAV RADIO page displays the VOR, ILS, and ADF radio
status and allows manual control of these radios. Entering data on this page tunes
the selected navigation radio. VOR courses can also be entered.
1 VOR Frequency andTune Status
Tuning status displays adjacent to left and right VOR frequencies. Entry of a
frequency or identifier manual-tunes a VOR. FMC autotunes VORs for procedure
flying and route operations. Tuning status displays are:
• P (procedure autotuning) – FMC selects navaids for approach or departure
procedure guidance
• R (route autotuning) - FMC selects navaids on the active route. The
navaid is the previous VOR or a downpath VOR within 250 nm of aircraft
position
• A(autotuning) - FMC selects a navaid for best position orientation
• M (manual) - VOR is manual-tuned

Manual-tuning takes priority over FMC autotuning. Deletion of a manual-tuned
frequency returns system to autotuning.
Valid entries:
• VOR or non–ILS DME identifier or VOR frequency (XXX.X or
XXX.XX)
• VOR identifier or frequency/course; the course displays on the CRS line
Tunes related DME.
Note: When magnetic variation at the airplane and VOR locations are
significantly different, the ND VOR radial and ND POS green radial do not
point directly to the VOR. This difference decreases as the airplane
approaches the VOR.
2 Course (CRS)
Blank when in autotune.
Valid entry is a three–digit course. Data can be entered when dashes or a course
display.
With a VOR approach selected, sequencing an IAF/FAF causes the FMC to
procedure autotune the VOR frequency. When the approach has a runway
waypoint, the FMC selects the inbound course.
