The modern airplanes beginning to be available at the time were more “spin-proof,” also, if there really is such a thing. As we recall the rationale for ending spin-training requirements for the private, more accidents were resulting from the training than it was designed to prevent. Spin training wasn’t required for our private certificate, either. Sometimes, it’s better to be lucky than it is to be smart! And I have had other sobering experiences. I landed, went home and had a stiff drink.įifty years and 7000 hours later, flying is still my passion. I pushed the nose down to windmill the prop and the engine started. I quickly realized I had not engaged carb heat. Pulled the power back and-wham again!-the engine quit. Now rattled, I decided to do simple arrival stalls. I was lucky, though, and quickly recovered. Wham! I was in a spin, no doubt the result of my being so focused on slow flight that I did not perceive I was in uncoordinated flight. Having conquered the world with slow flight, I decided to perform a departure stall.

Full power, stall horn yelling, I had it nailed. Having just learned slow flight, I decided to practice. On a nice day, I was soloing a Cessna 150. At the time, spin training was not required by the FAA. During training, my instructor taught me spins. I was learning to fly at Arrowhead Airport, a small field in St. The second answer is the airframe is much less likely to encounter extreme negative g loading in flight than it is the positive kind.Ĭlint Lowe’s article in June’s issue, “ Spin Training,” parallels my experience of some 50 years ago. Put in these terms, there’s not that much difference between the two values. Meanwhile, a certificated normal-category airplane must withstand -2.52g difference from normal. The positive g loading a normal category airplane can sustain is “only” 2.8g more than it’s subject to at rest, not 3.8. The difference, then, between the normal category’s +3.8g and -1.52g isn’t as great as it initially appears. The first involves the fact your airplane sitting on the ramp already is subject to 1g loading.

Good question, for which there are two basic answers. Question: Generally speaking, why can airplanes withstand (or be certified for) greater positive g load limits than negative? Stated another way: Why are negative g loads more restrictive? Banner’s article in July’s issue, “In-Flight Fires,” mentions to bank 45 degrees during an emergency descent to create positive g loading and help offset negative g forces.
