As I am attempting my PPL skill test in a couple of days, my 3rd flight instructor wanted to do some more practices... including on-purpose stalls... Stall means that the angle of the wing with respect to the apparent wind is too large, hence, the air flow is no more laminar but rather turbulent... Bernouilli's law does not apply anymore, i.e., the wing has no more lift = the force to push the wing 'up', and the plane falls... Light aircrafts as this Cessna 151 are designed by positioning the center of gravity in such a way that, in the absence of lift; i.e. when the wing stalls, the planes dive hence gaining speed and reducing the angle of the wing which solves the problem! STABILITY is key of course! The pilot's job is easy, when the plane stalls and BTW the alarm sound means that the wing is so much 'up' that stall is imminent, the pilot 'just' has to NO PANIC, release the control and put full engine power to quickly gain speed ... In order to make stalls on purpose, it is easy: reduce the engine power and try to keep the altitude unchanged, i.e., trading speed for altitude by increasing the pitch i.e. the wing angle of attack inducing speed... Q.E.D. Note: I have yet to practice because reducing/augmenting engine power has a side effect of banking the plane and I have to learn to compensate for it earlier... Note2: I also failed to record the intercom voice with my flight instructor :-(
