Good evening.
I was trying to create a flight plan from scratch using the MCDU. Some city pairs in INIT page do not work, for example LIRF/LEMD, KMIA/KLAX or KMIA/KJFK. Only the first part (for example LIRF/---) is displayed. Nevertheless if using Navigation menu it there is no problem. Strange thing as supposedly a flight plan can be created via MCDU.
Regards.
