Steep Spiral (ASEL, ASES)
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with steep spirals. Note: See Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Bottom line
The pilot may use any combination of normal gliding maneuvers, from wings level to spirals to eventually arrive at the normal key position at a normal traffic pattern altitude for the selected landing area. A constant gliding speed is usually maintained because variations of gliding speed nullify all attempts at accuracy in judgment of gliding distance and the landing spot.
