Dear Jet-Pack (IPACS)
Some waypoints are not found in the MCDU of the A320 whereas there are available in Aerolfy database (Navigation Menu).
For example: spawn the A320 at Zurich / Cold & Dark. In the MCDU, set departure RWY 28 SID VEBI3W and arrival RNAV 21 STAR VALA1A as shown on the attachment.
Then enter the waypoints:
LSZH VEBIT LASUN HR LUL RLP BALMU KUTAN OSKIN MOTAL GILUX DOMOD KOVAK LUMAN TUNAX SABLE ARDOD VALAX LFRS
In this case KUTAN will be impossible to enter (whereas I entered it with the Navigation Menu).
Maybe understand this specially case will solve the other cases.
