Teaching and Learning Flying - Private Pilot, Single-Engine Airplane

Turns Around a Point


DEFINITION

    A training maneuver in which the airplane is flown in two or more complete circles of uniform radii or distance from a prominent ground reference point using a maximum bank of approximately 45° and maintaining a constant altitude (AC 61-21)

SAFETY FACTORS

  • Select a ground reference point away from communities, livestock or groups of people and with an emergency landing area within gliding distance
  • Fly maneuver at VA with mix rich, prop high RPM, check temps (ready for emergency landing or max power recovery)

TOLERANCES

    Private Pilot PTS, VIII, C
    • Explain associated procedures and wind drift correction
    • Select suitable ground reference points
    • Enter left or right turn at desired distance and 600 to 1,000 feet AGL
    • Divide attention, coordinated
    • Apply necessary wind drift correction to track a constant radius turn
    • Altitude +/- 100 feet
    • Airspeed +/- 10 kts

OBJECTIVES

    To help the pilot develop the ability to subconsciously control the airplane while dividing attention between the flightpath and ground references and watching for other air traffic

PROCEDURES

  • Discuss definition, safety factors, tolerances, objectives, and other elements of turns around a point
  • How to select a suitable altitude
      Add 800 feet (600 to 1,000) to ground elevation
  • How to select a suitable ground reference point with consideration given to emergency landing areas
    • Small, but prominent (eg: intersection of crossroads)
    • Away from communities, livestock or groups of people
    • Emergency landing area within gliding distance
  • Orientation, division of attention, and planning
  • Configuration and airspeed prior to entry
    • May be flown at normal cruise, but
    • Safest may be: VA and mix rich, prop high RPM, check temps (ready for emergency landing or max power recovery)
  • Entry technique
    • Enter downwind in SLF at distance equal to desired radius
    • In high wing plane, stay close enough to see point throughout
    • Roll into initial bank at relatively rapid rate when abeam
  • Wind drift correction
    • Steepest bank on downwind (fastest groundspeed) entry
    • Then gradually shallow bank around to minimum when heading directly upwind
    • Then gradually increase bank to maximum when heading directly downwind
    • Bank is smoothly and continuously adjusted to maintain desired ground track
  • How to maintain desired altitude, airspeed, and distance from reference point
    • Divide attention outside and in
    • Constant power setting
    • Vary bank to apply appropriate wind drift correction
    • Visualize desired ground track circle and fly over or parallel to it
  • Coordination of flight controls
      Feel beginning slip or skid; confirm with ball in TC
  • Demonstrate turns around a point in flight
  • Coach student practice
  • Critique student performance

COMMON ERRORS

  • Faulty entry technique
  • Poor planning, orientation, or division of attention
  • Uncoordinated flight control application
  • Improper correction for wind drift
  • Failure to maintain selected altitude or airspeed
  • Selection of a ground reference point where there is no suitable emergency landing area within gliding distance
