death spiral

1. In aviation, a dangerous downward cork-screw maneuver of a disabled or uncontrollable aircraft that often leads to a crash. Also called a "spiral dive." The pilot, unaware of the plane's slight roll in the cloud bank, only realized he was in a death spiral when it was too late to overcome the dive. A: "What do we think happened to the victim?" B: "Well, he was a fairly inexperienced pilot, so my guess is he lost the horizon line in the poor weather and ended up in a death spiral." Any pilot could end up in a death spiral if they were to lose all visual cues.
2. In pairs figure skating, a maneuver in which the male partner, in a pivot position, spins the female partner with one hand in a wide circle with her body nearly parallel to the ground. The two pulled off an amazing death spiral—her head looked as though it were about to touch the ice at one point! If you want to advance in pairs figure skating, you've got to learn the death spiral eventually. I can't watch figure skaters do death spirals because I'm always terrified the female partner is going to whack her head on the ice!
3. In insurance (especially health insurance), a plan in which costs rapidly increase over time due to policyholders with a lower risk opting out of the policy, forcing those dependent on it to pay higher premiums, thus prompting more low-risk policy holders to opt out and further drive up costs, and so on. I purchased my health insurance plan as a means to afford my medicine, but it turned into a death spiral when employers started offering cheaper, barebones plans that the majority of people were quick to switch to. I don't know if I'll be able to keep the health insurance plan I want because it's in something of a death spiral, thanks to my co-workers choosing cheaper plans. If our current, more robust health plan is in a death spiral, how much longer will we be able to afford it?
4. In finance, a loan given by investors to a company in exchange for convertible bonds, which can then be converted to common stock at prices lower than the market value, causing overall share prices to fall and more bondholders to trade their stock for equity, ultimately leading to a collapse of the company's stock worth altogether. To keep his company afloat, Tom was forced to take a loan that ultimately proved a death spiral, leading him to close the business anyway. A: "The company is failing, and I don't know how to save it." B: "Well, you risk a death spiral if you take a loan like that." Is there any way we can get our business a cash infusion that won't also be a death spiral?
5. Any situation in which a series of events or actions, especially as a consequence of one another, ultimately lead to a point of ruin, failure, or destruction. With the recent allegations of drug abuse, corruption charges, and controversial remarks about minorities, the long-time senator now seems locked into an irreversible death spiral. No, you can't phase out the humanitarian aid program—that would create a death spiral for thousands of people in the impoverished region! The Stock Market Crash of 1929 was just the start of the death spiral that led to the Great Depression.
