Absolutely! It would be fantastic if you could store routes into the MCDU for later use. Would especially come in handy if you were flying for a virtual airline and flying routes repeatedly. I’m thinking the task of entering complex routes manually becomes laborious quickly.
The whole issue is the problems with the flight planner transferring data over to the MCDU, which I’m becoming quite fed up with to be honest. I’ve actually given up on airliners as of late because of this. I will say that any aircraft with Garmin equipment seems to work well with a transferred flight plan.
How does one register a “wish list item” such as this?
