During a steep spiral, a commercial pilot applicant loses situational awareness of altitude. According to the Commercial Pilot ACS, at what minimum altitude above the ground must the recovery from a steep spiral be completed?

  1. A500 feet AGL
  2. B1,500 feet AGL
  3. C1,000 feet AGL
  4. D2,000 feet AGL
Show answer & explanation

Correct answer: C. 1,000 feet AGL

The Commercial Pilot ACS requires the steep spiral to be performed with a rollout completed no lower than 1,000 feet AGL, providing adequate altitude for recovery and continued safe flight.

Why the other options are wrong

  • A. 500 feet AGL is below the ACS minimum and would not allow a safe recovery margin.
  • B. 1,500 feet AGL exceeds the actual ACS minimum for this maneuver.
  • D. 2,000 feet AGL is not the specified ACS altitude for steep spiral completion.

Steep Spiral Minimum Recovery Altitude

A gliding maneuver consisting of three or more 360° turns to develop division of attention and wind-drift correction, which must be completed no lower than 1,000 feet AGL.

  • Performed with power at idle in a continuous gliding descent
  • Bank angle should not exceed 60°
  • Maintains a constant radius around a ground reference point

Memory trick: 'Spiral stops at a grand' — 1,000 feet is the floor.
