It is confusing when there seems to be so much contradictory advice about getting out of a spin in a C152 - this is just one of many articles about 'letting go' of the controls and it will self recover. I've never spun a C152, but those who have, which method do you use?
"Spinning the Cessna 152
It is a hallmark of the tricycle wheeled Cessna 150/152/172 aeroplanes that they are difficult to deliberately spin when they are loaded in compliance with the Utility Category Certification. Load a couple of passengers and some baggage into a Cessna 172 and it becomes easier to spin, but the aeroplane is not in the Utility Category! To learn what a spin is really like you need to fly one of the following aeroplanes: Piper Tomahawk, Slingsby T67, Chipmunk, Condor, or most 'classic' training aeroplanes.
We are flying the Cessna 152 however so let's look at how we can simulate the spin...
'Spin entry'
There are two ways to enter the spin in a Cessna 152, you either flick/snap the aeroplane in, or you enter with some power. Flicking it in is very violent, this is often the way that frightens the student pilot and involves reducing the speed to around 50KIAS and applying full up elevator and rudder violently. The aeroplane inverts and enters a spin.
The nicer entry is to apply 1500 RPM and at 40-45KIAS apply full rudder and up elevator, this way the aeroplane enters the auto-rotation smoothly. Once established you must close the throttle.
In the spin
The Cessna 152 will spin for one turn and then it enters a spiral dive, so one turn is all this author does with a student! It's enough to get the point across. The aeroplane rotates due to the differential lift of the wings because there is yaw, the faster wing is developing more lift and so rotates upwards, at the same time the nose is yawing in the same direction. The aeroplane descends like a sycamore seed.
The Cessna 152 will recover if it is correctly loaded, and the power is at idle, by simply releasing the controls."
