  1. Approximately 15 degrees
  2. Approximately 30 degrees ✔
  3. Approximately 60 degrees

Why: In a lazy eight the pitch, bank and airspeed change constantly and smoothly. The bank reaches about 30 degrees at its steepest point, at the 90 degree mark of each 180 degree turn.

Huh, didn't know that: A lazy eight develops proper coordination of the flight controls.
