Home cockpit mode is a camera setting that is supposed to make the virtual cockpit disappear. It doesn’t. But that’s what it’s supposed to do. It also apparently prevents you from using freelook.
I think that the people who designed this feature had cockpit builders with full cockpits with wraparound screens solely in mind. For those people, maybe freelook would not be necessary. But there are many people who operate with an instrument panel and single monitor in front of them. And there may be many people who aren’t cockpit builders who simply liked the “W” key from FSX and want to fly without an instrument panel. For those people, disabling freelook means that you can’t look anywhere but straight ahead.
Looking around is necessary for avoiding runway/taxiway incursions at the airport, answering traffic alerts from ATC (especially when ATC tells you that you have traffic at your 6 o’clock ), collision avoidance in the air, and for VFR pilots who need to look around in the pattern/circuit.
Furthermore, I’ll add: If you do a search on “home cockpit mode” in the forums, you’re going to find several threads with people who say that freelook stopped working on them, only to discover that home cockpit mode was turned on, preventing them from using freelook. I don’t think it’s most people’s expectations that enabling home cockpit mode is also going to disable freelook, too. (Freelook doesn’t even get disabled in the menus when you enable home cockpit mode.)
It’s for these reasons that I ask the developers to consider decoupling these two settings from each other so that you can still do freelook while in home cockpit mode.
