the first Career Mode Introduction to Airliners tutorial requires you to press the TOGA button to take off.
except, you can’t press the TOGA button since the clickspot does nothing.
you can try binding a key to COCKPIT INTERACTION - SECONDARY ACTION (LOCKABLE), but that doesn’t work either.
so, the very first Airliner Tutorial is broken before you even get off the runway.
EDIT: i solved the problem. see below.
