Haven't noticed this little hatch before, probably because I usually don't look at the exterior views while in the air. What is it? Intake for the ventilation or something?

Exactly that. It's opened and closed with the little plunger control over at the bottom right of the instrument panel.JonasBecsan wrote:What is it? Intake for the ventilation or something?

Aha! A2A and their extremely detailed modelling. Love it!Nick M wrote:Exactly that. It's opened and closed with the little plunger control over at the bottom right of the instrument panel.JonasBecsan wrote:What is it? Intake for the ventilation or something?

Re: What's this?
The Skylane has the same feature btw Isn't it great how we can find some more detail by default sometimes

Re: What's this?
It's "DOOR ASSY-SIDE AIR VENT". Standard equipment through the Cessna fleet, luckily. Breaking it would set you back some $300-$400 for a spare in new condition apparently.
That door, btw, lets the air into the heated air distribution, where it may or may not get mixed with heated air, depending on the position of cabin heat knob. The cabin air knob controls the door, letting air into the system and the cabin heat knob adjusts the mixing of that air with the heated air. The openings in the leading edges let the fresh, unheated air directly to the vents in the cabin, unheated.

Re: What's this?
That's interesting. So when I only pull the cabin heat where does the air come from? Does that door also open? I'm guessing the heated air comes from the engine compartment and is heated by the exhaust pipe, correct?AKar wrote:It's "DOOR ASSY-SIDE AIR VENT".

Re: What's this?
If you open the cabin heat without opening the cabin air, you get very little hot air flow. Both need to be opened to get a decent amount of flow.

Re: What's this?
Interesting. Thanks for the reply Oracle. I guess that's something that can't be felt in a simulation

Re: What's this?
When you pull just the cabin heat knob, the air comes in through the shroud that is installed over the exhaust muffler. The air is ram air taken from somewhere up front - never paid attention on the hosing arrangement in the only 172R I've seen, but I'd guess it should be immediately obvious if you take the cowls off and check it out (or if someone posts a photo! ). There is no externally visible door that would move for it but it is controlled where the hose from the heater shroud comes to a duct, where it mixes with the fresh ventilating air from the side door, behind the firewall. I'd figure it takes some ventilating air to pick a good flow through the system, Oracle mentions the heat alone does little. Likely opening the ventilating air helps to pull the air through the heating system as well.Piper_EEWL wrote:That's interesting. So when I only pull the cabin heat where does the air come from?

Re: What's this?
It was foggy here in London this morning when I took her out for a spin. The windows appeared to have condensation on them but a few minutes of cabin heat (with that little flap open) and the windows cleared. I didn't imagine that did I?
It is little touches like this that make this sim so utterly impressive. Although I am still getting the hang of flying it in a straight line, I can't praise the workmanship in the C172 highly enough!

Re: What's this?
No you didn't imagine it. The windows actually fog up under the right circumstances. Your in for some special treats with the Accusim C172. Stuff failing etc. it's a lot of funWasabi65 wrote:It was foggy here in London this morning when I took her out for a spin.
