Some pilots aren’t totally sure of the differences between a spin and a spiral dive. That’s OK in the classroom setting when discussing aerodynamic theory, but it can be dangerous in the cockpit should either flight condition be allowed to develop and the pilot doesn’t immediately know what’s going on or the corrective actions to take.
Spiral Dive Recovery
Key Takeaways:
- A spin is an aggravated stall with high angle of attack and at least one wing below stall speed, whereas a spiral dive involves an accelerating, non-stalled aircraft in a tightening spiraling path.
- Recovery techniques differ significantly: spin recovery aims to break the stall by reducing angle of attack and increasing airspeed, while spiral dive recovery focuses on reducing speed.
- To recover from a spiral dive, immediately reduce power to flight idle, bring the airplane to wings level with coordinated controls, and then use elevator inputs to achieve straight and level flight, mindful of high airspeeds and potential structural limits.
