Fix Info
Only available in the Experimental Version
Overview
The MCDU FIX INFO page is used to create radial lines and distance circles around a database navigation fix.
These lines or circles are displayed on the ND and also used to compute intercept waypoints which can be added to the active flight plan.
The current Experimental version of the A32NX has implemented the display of these lines and circles on the ND.
The computed intercept waypoints and ABEAM functionality are not yet implemented.
Use Cases
Fix info is a powerful supplemental tool for pilots to improve situational awareness and easier, more precise navigation.
Common use cases are:
- Top of descent circle, to display the exact point on the lateral path when to start a descent into a specific fix.
- ILS localizer extension line, to easier identify where the localizer beam should be in extension from the runway
- VOR intercepting
- Go Around procedure aid
Step by Step Guide
1) Where is the FIX INFO page?
You will find the option to select the FIX INFO page on the top most waypoint of your active flight plan.
For this go to the MCDU F-PLN page and select the top most waypoint with the left LSK (line select key).
This brings up the lateral revision page for this waypoint and also displays the FIX INFO page option. Press the right LSK next to FIX INFO
2) Enter a Navigation Fix
3) Enter Radial or Radius
With radius 63NM around the waypoint ABTUM:
4) Additional Fix Info Pages
You can define up to 4 different fixes by selecting the horizontal skew navigation button to go to the next page.
Examples
Top of Descent Circle
FL340 with arrival TEBRA2G into Gatwick EGKK.
A descent is required at 63NM before ABTUM as calculated by the flyPad Top of Descent calculator.

ILS Localizer Extension Line
To visualize the ILS localizer for the approach the runway fix can be used to display a radial line corresponding to the ILS track course.
VOR Intercept in SID
In this scenario we have a departure on 36R in KMCO (Orlando) with the ORLANDO 4 DEPARTURE SID (ORLA4). This departure expects ATC to assign headings after departure to intercept the filed/assigned route.

As you can read in the Initial Climb description for 36R we need to meet certain altitudes at different positions in relation to the ORL VOR.
- Cross ORL D2.0 south of ORL at or above 2.300ft
- Cross ORL R115 at or above 2.600ft
- Cross ORL R090/R270 at or above 3.000ft
To visualize these points we can use the fix info page to define a 2NM distance circle and 2 lines for R155 and R090/270 on the ND.
