Vandoorne has shared the Aston reserve job with Felipe Drugovich this year, essentially fitting in trips to grands prix around the Formula E calendar.
As well as driving the simulator, he also had his first chance to sample the AMR23 on track in a Pirelli test at Spa.
However, next season he will run the full WEC schedule alongside his Formula E commitments, which will reduce his availability to be on duty for Aston on grand prix weekends.
Despite his congested schedule, the Belgian believes he can still make a useful contribution to the Silverstone team.
"Obviously, it gets quite busy, and there's only so many days in the year to get around," he told Autosport.
"But I think it's still possible to be involved with Aston. It requires a bit of management with all the parties, and everyone needs to be very aware of what the priorities are, what my availabilities are.
"As long as everyone is on the same page with that, then that's possible. I think, above all, it's up to me as well to be very clear about that with all the parties, in terms of where to put my time, but also how to manage my whole travelling and my energy levels, because there's a lot of time being spent on airplanes. I'm making sure that does not affect my racing."
In some cases, Vandoorne’s travel schedule will work in his favour, for example when the Tokyo Formula E event is followed immediately by the Japanese GP weekend.
