In a spin, how much altitude is generally lost per turn when erect?

• A. 200-300' per turn
• B. 300-400' per turn
• C. 400-500' per turn
• D. 500-600' per turn

Answer: (C)

In a spin, the altitude loss per turn can vary based on several factors, including the aircraft type, weight, and the specific spin condition. Generally, when an aircraft is in a fully developed spin and is erect (meaning the wings are level), it is expected to lose between 400-500 feet of altitude for each complete turn.

This altitude loss occurs due to the vertical component of the spin descent combined with the energy dissipation as the aircraft continues to rotate. The dynamic nature of a spin means it can result in significant altitude loss relatively quickly. Thus, the range of 400-500 feet lost per turn is a standard figure often referenced in flight training and aeronautical literature, explaining why this choice is considered the correct answer.

The other options reflect altitude loss ranges that either underestimate or overestimate the typical altitude loss experienced in such scenarios, based on standardized flight training data.
