I added a line of code to show me which was the closest airport detected
(patch attached) and was amused to notice the following:
dominatrix:~>fgfs --aircraft=CitationX --airport=EGPF
Error: connect() failed in make_client_socket()
SG_IO_OUT socket creation failed
VOICE: no connection to `localhost:1314'
Electrical System ... ok
Flight Director ...Check
Primus 1000 systems ... check
Chat [*FGMS*] alcam is now online, using
Chat [*FGMS*] this is version v0.9.11 (LazyRelay rev 1.14)
***********ALI **closest airport is FSPP PRASLIN
Segmentation fault
