Lesson 14.6:  Wind Indicators & Traffic Patterns

Airport Wind Indicators

     Reference: ACS PA.III.A.K1 - K9, PA.III.B.K1 - K4 PHAK Chapter 14

Wind indications are provided by both wind indicators and ATC or FSS at towered airports.  But, at non-towered airports where there is no source of verbal communication of the current winds, wind indicators are used.  Indicators are found near the runway and located in a segmented circle, which shows the traffic pattern directions. There are a few types of indicators used.

  • Wind cone

  • Windsocks

  • Tetrahedron

  • Wind tee

 

TIP:

    The windsock should be used as the primary source of wind information.

Traffic Patterns

​At non-towered airports segmented circles are located in an area near the runways that pilots can easily see it from the air.  Segmented circles are to provide basic traffic pattern information. 

  • At most airports and military air fields the traffic pattern altitude (TPA) for piston aircraft is 600 feet up to 1,500 feet AGL. 

  • Traffic pattern altitude for military turbojet aircraft is 2,500 feet AGL

  • To find the exact traffic pattern direction and traffic pattern altitude (TPA) for any airport can be found in the Chart Supplement U.S. 

TIP:

    Traffic pattern altitude (TPA) for piston aircraft is recommended 1,000          feet AGL above airport elevation. Unless otherwise established.
