A tip for the Cessna 150/152/172 aircraft, when on the approach to land ensure that the ventilator tube into the cockpit from the wing is opened. You can hear the change in sound as the centre of pressure moves forward as the angle of attack increases. It used to be a good way to demonstrate a precautionary approach with a covered or failed Air Speed Indicator.
So that's what causes the wheeze in the flare... often wondered!
