P3Dv4.5 iFly 737NG - crash

Navigation Data General non MSFS data
14

Gentlemen,

This is an iFly 737 bug in P3Dv4 … I can confirm the crash and it´s reproduceable.

The reason seems to be the number of waypoints in the wpnavfix.txt file. When the file contains more then 300031 lines, the sim crashed.

I have attached two zip-files where you can simulate this - both are from AIRAC 2310 and are identical but one has 300032 lines (crashed) and one has one line less 300031 (no crash):

  1. wpnavfix.txt file with 300032 lines → CTD
    WPNAVFIX_2310_300032_lines_crash.zip (3.9 MB)

  2. wpnavfix.txt file with 300031 lines → no CTD, iFly 737 is loading normally
    WPNAVFIX_2310_300031_lines_no_crash.zip (3.9 MB)

So, it looks as if there is a hard-limit in this version, but really more details can only be traced by iFly.
Sorry, it´s an iFly issue and not a navdata issue.

Cheers,
Richard

PS: AIRAC 2309 had 299247 waypoints/lines in the wpnavfix.txt file - therefore it was working too
