Cessna
Does anyone know the source of the weird sound Cessnas make as you flare? Like this..at about 2.20 to 2.30 (not the stall warner) sort of a sound like gas escaping from a bottle. I reckon it might be the wing air intakes for the cockpit ventilation but I'm not sure.
Sound is from the stall warn. In the C 172 it is a trumpet with a reed in it. Unlike the electrical vane type it is not a on/off unit. You will hear the air rushing into the trumpet before there is enough air flow to push the reed over enough to sound the horn.

I've asked this question before. Our c182 does it as well usually when heavily loaded. Ours has an electric stall Warner which goes off at the same time.
I thought the noise may come from the flaps but you may be correct.

I've also wondered this. Doesn't seem to be stall horn related. For me it's always when I pull the nose up to hold-off, then flare. I put it down to a change in airflow around the cabin/windscreen as the pitch is increased and power reduced.

It's before the wheels touch the ground. Happens on a 152 as well but not a PA28.so it's obviously something peculiar to Cessnas.
