Eights on Pylons (ASEL, ASES)

FAA references

Knowledge

• CA.V.E.K1: Purpose of eights on pylons.
• CA.V.E.K2: Aerodynamics associated with the eights on pylons, including coordinated and uncoordinated flight.
• CA.V.E.K3: Pivotal altitude and factors that affect it.
• CA.V.E.K4: Effect of wind on ground track.
• CA.V.E.K5: Phases of the eights on pylons maneuver from entry to recovery.

Risk management

• CA.V.E.R1: Division of attention between aircraft control and orientation.
• CA.V.E.R2: Collision hazards.
• CA.V.E.R3: Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
• CA.V.E.R4: Distractions, task prioritization, loss of situational awareness, or disorientation.
• CA.V.E.R5: Uncoordinated flight.
• CA.V.E.R6: Energy management.
• CA.V.E.R7: Emergency landing considerations.

Skills

• CA.V.E.S1: Clear the area.
• CA.V.E.S2: Determine the approximate pivotal altitude.
• CA.V.E.S3: Select suitable pylons that permits straight-and-level flight between the pylons.
• CA.V.E.S4: Enter the maneuver in the correct direction and position using an appropriate altitude and airspeed.
• CA.V.E.S5: Establish the correct bank angle for the conditions, not to exceed 40°.
• CA.V.E.S6: Apply smooth and continuous corrections so that the line-of-sight reference line remains on the pylon.
• CA.V.E.S7: Divide attention between accurate, coordinated airplane control and outside visual references.
• CA.V.E.S8: Maintain pylon position using appropriate pivotal altitude, avoiding slips and skids.
