Hey! Radarman,
This helped me completely! Many thanks for your assistence.

This is a very good video, from start to push back and start of engines.
Is there a following video, which shows also the other procedures built in in the Scheffel B737? I would love to see those as well.
Anyhow, many thanks again!
