Purpose
Is to provide a flight maneuver for rapidly dissipating substantial amounts of altitude while remaining over a selected spot.
This maneuver may be useful during an emergency landing.
A steep spiral is a gliding turn wherein the pilot maintains a constant radius around a surface-based reference point
Similar to the turns around a point maneuver, but in this case the airplane is rapidly descending
Procedure
Setup
Select an altitude that will allow the maneuver to be completed no lower than 1500’ AGL. (4,500’)
Determine the wind direction.
Perform the PRE-MANEUVER FLOW and make a position report (see page 2-26).
Select a reference point in an area where an emergency landing can be made if necessary.
Entry/ Maneuver
Bug heading
Enter on downwind,
Enrichen the mixture slightly
Reduce throttle to idle(smoothly and slowly to prevent engine backfiring),
Adjusting pitch to establish and maintain an 80 KIAS descent. BEST-GLIDE
Trim as necessary
Abeam the reference point,
Roll into a steep bank (50-55°),
Adjusting the bank angle as necessary (not to exceed 60°) to
Maintain a constant radius around the reference point.
Complete three 360° turns. (clear engine in the upwind/ periodically)
Exit
Recover no less than 1500’
Exit on entry heading/ downwind
Set cruise
Common Errors
Not clearing the area
Inadequate pitch control on entry or rollout
Not correcting the bank angle to compensate for wind
Poor flight control coordination
Ineffective use of trim
Inadequate airspeed control
Becoming disoriented
Performing by reference to the flight instruments rather than visual references
Not scanning for other traffic during the maneuver
Not completing the turn on the designated heading or reference
