Hi, this feels like it's a really stupid question but I can't find concrete information on it in the manual or online, so here goes.
Occasionally a small left-to-right arrow appears laterally across the TVV, but I have no idea what information it's trying to impart, or under what conditions it appears.
I've a feeling it might be trying to tell me I'm in a crosswind, but I can't be 100% about that. Does anyone know what I mean and what it's for?
