Hi Mario

Thanks for your reply,I have just cut/paste the airport.db from your post and now i can enter VHHX into FMC,but the runnway.db (This is VHHX:
VHHX ; Hong Kong Intl (old)    ; 13 /31 ; 134/314; N22°18'52.65; E114°12'16.63; 00000; 10980; 200; 000.00) does not look like this in the file it looks like your LEPA;3;110.9;39.547147;10725;2.710728;06L;059.

I would not be able to convert,could i please ask you to do it for me if you have the time,It would be much appriciated.
